Sorry to resurrect an old thread. I'm going to load some of this bullet this afternoon.

7x64

26", 1:8.25" Bartlein

RS70 and hoping for something in the 2700 fps range

Scrummy

Can I politely suggest starting a new thread as you aren't loading for 284Win.

When load data is shared for same bullet/different case but in the same thread, there is a risk of confusing subsequent readers of that thread, with safety implications.

I've had a duff scope (blurred), a mis-sold scope (was told it had mil/mil ret/turrets; it had mil/MOA), bullets that had been pulled (collet dent and scoring), brass that was utterly shagged (pistol cases: splits in necks but many had splits in web!) and a "low-shot-count" full custom rifle that had a pitted-crown. 

In all cases the seller sorted it out (well, one is in the process of sorting it...) without issue.

MOA turrets, MIL reticle...best of both worlds 🤩

That's evil. 

To the OP: Do NOTdo this!

As above, shoot what you're comfortable with.

Personally, if all else was equal, I'd use the 260Rem (being able to see your own hits/misses is a crucial part of PRL and I think recoil will be easier to manage with it than 300WSM.)

As for 6.5mm bullet choice...

123Scenars are not to be underestimated in the speed/BC equation, though most shooters are favouring the >140gr offerings (including the new A-Tip, if your wallet and twist-rate can handle it.) Low recoil and quite cheap if bought "repackaged" in bags.

The Berger hybrids reportedly work well but are more costly.

I have been happy using the 130TMK but I'm using 6.5x47Lapua so slightly less in the engine room than 260Rem and Creed. 

I have rifles in 7WSM and 284Win but they are better suited to ELR than PRL in my view.

The organisers don't like steel or tungsten penetrator tipped bullets (milsurp) and maybe monolithics? Check the rules or wait for someone more au fait with them to chime in.

Until you've shot a few comps or training/taster days don't spend a fortune on new guns and kit. I used my 308Win deer rifle and 5rnd mags for many RRCs (before UK PRL) and did not feel the rifle was holding me back at that stage. 

Yes please

Lube?? Dont I just press them into the case as per centrefire? 

Commercially available cast bullets will usually be lubed already.

There are some other differences compared to loading jacketed bullets, eg the need to slightly Bell the case mouth and, in some cases, expand it too. Crimp also important in revolvers and tube-fed rifles

I'd do a bit more reading around the subject; there seem to be gaps in your knowledge and you can't safely rely on a forum to find and fill them. 

The Lyman cast bullet handbook is a good starting point.

I don't think the zero stop should (nor could) induce this problem.

If you remove the zero stop or reset it at a different point in the range of elevation travel, does the problem persist in the same manner?

Is your windage near either extreme of adjustment?

Is your zero stop set to be near the absolute minimum of elevation adjustment?

If your zero stop is at or very near minimum elevation (usually only the case with steeply angled bases or rings for long range but still zeroing at 100m) you might see this phenomenon. 

If in doubt, contact Vortex UK and they will sort you out (quickly, under normal circumstances), UK distributor below:

Hello chaps purchased a quick trim die and cutter for the 17 hornet cases i have tried everything but it will not trim the cases the cases are .005thou over size any help would be good

Might be worth starting a separate thread in the appropriate sub forum, Skydancer. 

Is it the Lee quick trim die and cutter? I don’t use them myself, so can’t advise. A photo of your set-up with a case in position might help clarify. I assume you’ve set it all up according to the instructions. 

When you say 0.005thou over size, do you mean 5thou ie. 0.005inch (it can’t be 0.005thou unless you’ve got some extraordinary measuring kit!) 5 thou over length what value are you using for reference, ie. 5thou over what? The max trim length? The “trim to” length? What is the value/actual number you are using and where did you get the number? 

How many firings are the cases?

You might be trying to trim cases that don’t need trimming yet.

The 17Hornet is a small case, some set-ups need an extended shell-holder to work with it. 

I'd have bought this if I didn't already have its black/green brother, the GSBL. Love it!

I recently bought a secondhand Vortex scope on UKV. 

It had a problem so I contacted Vortex UK distributor and sent it in. (The private seller on UKV was entirely helpful, BTW, but it seemed sensible to go to Vortex) 

A brand new scope arrived by return of post. Refreshingly simple, no questions asked, no receipt needed.

Thanks for the reply. This is just theoretical and me gathering knowledge for now for a future build but yes I do imagine it would be a flat-top. That's just what I was thinking about getting your head low-enough as well, which is one of the reasons I made this post.

I think when I eventually get my build sorted I'll ask the gunsmith if I can come down with my scope and mount and him fit it while I test cheek weld and adjust the stock so I get it set up right first time and should take no longer than an hour. Then I'll know if I need a riser at the time and see if he has any recommendations.

I'd also like a quick-release ideally, but failing that I was thinking a Tier One Monomount. Just had a look at the AD quick-release cantilever mount as well as the Spuhr (certainly pricey as you say!).

Whilst we're on I may as well ask something else - what's the application of different angles on mounts I see (0, 20, 30 MOA etc?). I'm very new to this sort of thing so it's an extra spanner in the works for my decision making haha. Is there a certain mounting angle people prefer for CSR ranges? If someone could give me a brief explanation it would be much appreciated. 

On a flat-top AR it’s not usually a matter of adjusting stock for correct height- the buffer tube within the stock limits how low you can get your head. While it’s possible to build up the stock or fit a riser if your head is too low, this is not usually the direction you need to go for a flat top.  It’s usually a case of raising the scope by using the right mount. 

As for the angled base, a +MOA tilts the front of the scope downward, effectively giving you extra elevation adjustment in your turrets. 

This won’t always be necessary but if you know you’ll be shooting long range or using a scope with limited adjustment or a calibre with mortar-like trajectory (458SOCOM, subsonic 300Blk) then it may avoid or reduce problems. I have +20 MOA for mine, as this doesn’t prevent zero’ing at 100yds, doesn’t cause “half-mooning” and still gives that bit of extra elevation.

Just curious what people tend to find is the best mount height for scopes on an AR15? Do people usually opt for standard rings or high / extra?

The answer will depend on the AR. Is it a flat-top? If it is, you may need cantilever mount to get eye relief but also significantly higher than mounts for a “conventional“ rifle or you won’t be able to get your head low enough to see through the scope (ie. the opposite of the usual problem of getting good cheek weld with a trad stock.) 

I have 3 AR flat-top uppers: scope height above bore is typically 2.75”, compared to 1.75” on my “traditional” rifles. No riser required for a snug cheek-weld.

I use American Defense (I can’t afford Spuhr) but for the money I was impressed with AR-Stoner mounts.

Please could I have the code?

ok chaps have taken all your information in i have got the 20grain heads shooting ok with littlegun i dont know why the other hodgens powders are not available they say they are none compliance what ever that means

A quick search for REACH compliance will answer that: lots on this and other forums. 

Lil Gun (not little gun, they went cute with the name!) is REACH compliant, as are a few other Hodgdon powders like CFE223. However, they may become harder to obtain if importers aren’t placing orders for Hodgdon powders. I hope not as I use Lil Gun for the 20gr Vmax in 17Hornet and 300Blk loads.

hi all new to the forum having trouble getting powder for 17hornet 25 g heads went to the shooting show and got hold of some lovex d063 but cannot find any load data for this powder it seems to start on the 22 hornet not the 17 hornet can anybody help please

Lovex DO63 is made by Explosia, who made the same powder for Accurate but called AA1680. They used to be the exact same powder (I have tubs with a sticker proclaiming this) and data could be interchanged. However, this could change (or already have) since the companies have parted ways... 

I worked-up a DO63 load for 25gr Vmax, Hornady brass, CCI BR primers. It was over 11gr but as already stated, use small incremental increases as the percentages/margins are relatively tighter in a small case compared to bigger. 

The Hornady factory 20gr Vmax load was  slower than advertised when I chrono'd it in my standard barrel CZ527 Varmint: in fact my 25gr Vmax DO63 homeload was surprisingly close in velocity! 

If you decide to try Lil Gun, while Hodgdon do list loads on their site, I found I was getting pressure signs well below their max load, even in cold testing conditions so be warned! (Same baseline parameters as them, otherwise).

Both Lil Gun and DO63 seem to be mucky powders so clean well to avoid corrosion. 

I want to neck size my brass, just bumping shoulder enough to chamber but trying to avoid headspacing off the rim. Haven't bothered to buy new dies yet as the accuracy has been satisfactory without, thus far.

Consider fabric ones from Practical Precision.

This is a good option unless you don't have a suitable surface for sticking the velcro.

I cut a mouse mat and superglued it to my cheek riser. Took 10mins to do and is super comfy, hasn’t budged an inch and was cheap as chips. Looks good too...no fraying.

Great idea but doesn't sound like a Hoptic Quiver though.

There are certain factions of the so called 'shooting media' , or shall we shall social media/self important/self promoting individuals who seek to undermine the NRA because of A, it's not their bag, B, they have personal axes to grind and C, there is no doubt some jealousy going on.

The Bisley shooting ground is a civil dispute over tenancy where the Landlord has given notice that the lease won't be renewed and the tenant claims that there was a nod and a wink agreement in the past which should be legally binding.

Likewise the previous 'Artist Club' dispute was a privately owned club/business paying a peppercorn rent of circa £9k per annum in leafy Surrey for the clubhouse and didn't feel they should have to pay any more. The tenuous past links to the SAS (now it is privately owned/run and nothing to do with the Artists Rifles) were milked to court support and favour.

Personally I don't think you'd be able to rent a single desk office in Surrey for £9k, so the NRA appeared to be within their rights to seek market value IMHO and the same applies to the clay grounds.

It's just that some people seem to think it is good ammo for their own agenda to undermine the NRA. 

The shooting community are their own worst enemies at times.

 

 

Indeed. 

And now, perhaps as a result of all the noise, the Charities Comission (CC), are taking a close look at the NRA and whether it fulfils it’s stated charitable role. 

Charities are allowed to run businesses to raise funds for their charitable work. Some might be surprised that recreational shooting (and the rents, range fees etc at Bisley) may be the business that the NRA use to support their charitable role.

“So what is the NRAs charitable role?” I hear you ask.

I was slightly surprised when I found out.

“The charity’s purposes, set out in its governing document, fall under the promotion of the efficiency of the armed forces of the Crown, or of the efficiency of the police, fire and rescue services or ambulance services, which is a charitable purpose set out by Parliament in the Charities Act.”

Link to NRA response:

I have used N140 and Varget in 308Win and 223Rem but now use RS52 for both (same accuracy but better velocity, probably harder on barrels).

In both calibres I am loading to "mag length".

My RPR shoots best with 168-180gr bullets, particularly Sierra TMK, though SMK also v good. 155gr (Amax and SMK) were OK but not as good as the heavier options. I have been using Lapua Palma brass (small primer), which gave better results than Lapua large primer brass.

Strangely, the rifle also likes 125gr Sierra SMK, though I use N130 for that. 

There is plenty of  official data for N140 in 308Win so I won't share my load as there is no guarantee it will work in your rifle or be safe (and it is Palma brass). If velocity matters (getting the 20inch barrel of the gen1 RPR to stay above transonic zone to 1000yds, for eg) then RS52 might be a better bet.

I’ll buy this, please.

EDIT- I’ll take this please: I see from Lantac website that it’s a crush washer (which they stock)

Hi Greyman, how is this timed? Does it come with a peel washer or new crush washer? Or is there a clamping mechanism built-in?

Thanks.

Looks like a good set up.
