You're welcome to have the rail to try if you like (it's difficult to measure accurately), it's no use to me... PM me... If it's correct, I'm sure RPA would be able to supply a picatinny version.

It would make sense for it to be  a Quadlite, HPS might well have drilled your Swing for a previous owner and a Quadlite rail would be something they would have to hand.

Thanks, I'll message you later

Thanks both,

I have been looking at the Lyman 4^th Ed. Cast Bullet handbook.

Lyman publishes data for the 240gr #429667 out of a Rifle (This looks to be a RNFP or maybe a truncated cone). It isn't gas checked and includes load data for Unique, N110 and H110 so makes me wonder what’s possible.

The other thing with the Lyman data is the bullet is seated at COAL 1.645 which is a) Longer than CIP spec (1.61") and b) the Shellhouse bullets have a seating depth at rather less than that (About 1.58" as memory serves) if you want to crimp into the cannelure.

So, thoughts welcomed. Can you shoot plated bullets as fast as gas checked?

Scrummy

I just load to SAAMI spec in the Lyman 49th edition.  Roll crimped.  I've never shot gas checked lead so no info to share.

Hi folks,

looking for a 44 mag load with a cast lead 240gr RNFP (Shell House) that is supersonic (for electronic targets).

I have Unique but happy to look at other powders.

Scrummy

Viht N110 works well but I think you will suffer gas cutting issues trying to push cast lead without gas checks.  I tried it and leaded up my barrel like a church roof.

I shoot some jacketed 240gr at "full power" loads with N110, works ok but accuracy is pants compared to a light load of Unique with cast lead.

Thanks Mat but it looks different if I'm reading your info correctly.

You could try a parallel rail but use offset rings as Burris XTR rings (Optics Warehouse). I think incline is up to 40 MOA max.

Thanks, I know that's an option but a rail is my preferred method

I have a Swing SIN71 that's had a Weaver rail fitted some time in the distant past.  The receiver was drilled and tapped to accept what was probably a standard rail for some other gun.  The rail is around 7" overall with a hollow (concave) profile to fit a rounded receiver.

I've dimensioned it in inches as it appears to be sized as per.

I want to fit a 20moa picatinni rail so knowing what the Weaver rail was designed to fit would be a great start.  I have appended a sketch if anyone can help please?

i will def take a look when i see one.. but i dont see S&B and NF shares selling fast..you find in life as with scopes, there's a reason why Rolls-Royce and Fords have a price bracket, you get what you pay for! 

Indeed

Most people pointed me towards lapua 155s and had a reasonable load but nothing flash so I moved onto Berger and hornady and started to have much better results that those older chaps were asking me what I was using , now they’re all using Berger. Reading Bryan litz book I wouldn’t of bothered with lapua as they don’t suit my twist rate . Live and learn eh . I’ll now pick a bullet to suit twist rate and speed and maybe compromise a little on ultimate BC . That said the older chaps are all using TRGs and they will suit lapua with the 1:10” twist . Didn’t know all that stuff when starting out . Knowledge is power so pass it on but also pass on the intracies of twist and barrel length . Cheers

Very secretive with loads regarding club comps mate . Don’t want us newcomers beating the old hands ???? . Took me a lot of persuading to get info re what’s a good starting point . Happy with my loads now 7 years later  . It’s just how it is with clubs . Cheers 

Not in my experience at all and I'm willing to bet there's a lot of 'old hands' on here that would agree with me

Marc wanted info about our hand loads in 2019 , all that testing then give away your secrets !!!! . It was a form from Helen via email. Will see what happens in the future. 
Nowadays happy to pass on info if it helps newcomers. It was a nightmare years ago getting info from clubmen as to where I should be looking for reloading. Cheers 

This sounds a bit like paranoia,  there's plenty of data available on-line and in manuals and anyway, one person's load may not suit another's rifle or indeed be anywhere near.  Why on earth would anyone keep "secrets" ?

It's about safety / insurance / arse-covering (take your pick).

No i deer…… how do you find the Eldm’s  for being ‘fussy’ in 308?  Only asking because I use the Eldm’s 285grn in 338 ( excellent bc to weight ratio) but in a couple of barrels they do not shoot as well as Scenars which are easy to tune.

I have found ELD-Ms unusable in my .308 even after much faffing around but I have used them in .338 like you and they are almost as good as the Lapua 300 Scenar.

I use 155 Lapua Scenario in a 24" 1:11 twist.  43.5gr Viht 140.  Good to 900 at Bisley last week.  Struggled a bit at 1000yd.

Latest club info infers that landmark at catterick are wanting to limit us to factory ammo only ??

How implies?  Your club ?  if so I wonder if they've had instruction from DIO (it's not Landmarc's call, they do as they're told).

There's no advice generally issued to clubs I'm aware of - I would have seen that as a Club Sec.

Not new. This requirement was introduced shortly after the 1988 Firearms Acts changes that banned self-loaders, so must have been c. 1989/90. I can remember photocopying a pro-forma slip at work and filling in the blanks for multiple loads / cartridges and taking them to club range days at MoD Strensall. I was never asked to show one to anybody on site then (MoD wardens, pre-Landmarc) and never heard of anybody else being asked to. So, after 12 or 18 months nobody bothered any more about this.

As well as quoting the data-set source and affirming the handload used conformed to it, it was primarily a declaration that one had loaded ammunition in accordance with the prevailing MoD MV and ME ceilings. This was long, long before today's tighter limits and the resulting HME compliance regime was instituted of course and one could have loaded up compliant 338LM ammo for most sites.      

Interesting,  I used to be a regular shooter at Kingsbury and also organised the bookings, RCO etc.  Never asked to provide anything either by DIO or Landmarc.

Had to give our hand load info to Marc at the old eskdalemuir range  ie bullet , brass , powder type and how much powder . So why not everywhere ?? . 

never done that

our club has not been told anything and we shoot at bisley but i will ask the club chairman

Not applied at Bisley (so far).

How many have seen and submitted the NRA "Handloaded Ammunition Declaration" ?   I see it's required for Birmingham Bisley.

Do we know if MoD now implemented this for all DIO range bookings ?

I do love a good machine tool!

Whoever sold it to you (assuming a dealer/shop) is responsible and is legally obliged to fix it or refund the dosh.

I would be very cautious about heat treatment to anneal the receiver,  this really needs knowledge and experience to proceed safely,  ideally someone who's done that and proven successful.  Suggesting local annealing without affecting the lugs sound like the use of a torch flame - a very difficult to control process I'd think.

There's a member on here that is qualified to offer an educated view;  he may be lurking in his sett..

Bought new, fired once, would not collate adjusted sensitivity to "5" and the screen is permanently stuck on "Setting Thresholds" when you boot it on ... any clues, no answer yet from the manufacturer ... and the seller does not do Mondays... 

try taking the batteries out and waiting 30 seconds before refitting and see it'll boot up correctly

I am not an F Class shooter but would assume that you need the maximum velocity, burning 100% of the powder whilst maintaining minimum harmonic disturbance of the barrel/muzzel.

Consistency is key, if you can repeatedly throw the same wieght, high BC, bullet @ XXXXfps with POA adjustment you will repeatedly hit the target in the same place.
It all sound easy .....  but it isn't.
It's also remarkably expensive to achieve.

You need:
A good and accurate set of weigh scales.
A precision measuring caliper.
Brass cases with the same internal volume.
Bullets that weigh the same.
A rigid, consistent press.

I don't shoot above 300M so +/-20fps is about my limit and I find that difficult to achieve (not impossible).
+/-50mm @ 200M is fine for the targets/distances I shoot at.

±50mm ?  at 200m.  OK, that's approx a 2moa group.  Do you mean that ?

one casts aspersions;  dispersions are what we do when, for example, dropping a tray of primers

I couldn't help myself...😁
