why did phoenix say its no good on a s/b 8x56 i thought the digiex was a  scope you dont need no add ons  ? dave

I guess Bruce was refering to near add-ons. S&B coat thier lenses to allow the blue/green spectrum to pass. The coating is specifically designed to let the visible spectrum of light pass so the sight picture is bright and vibrant. These coatings are detrimental to the IR end of the spectrum consequently NV add-ons perform poorly on these high end 'day' scopes.

Sightron, Delta and most of the other mid-range scopes as well as the Hawke range perform much better as thier lens coatings pass infra-red uninhibited..

I like thge RifleKuhl ...  neat idea

I get my data from either the Hornady ballistics app or strelok. I can see already that reloading is going to be addictive 😀

Both of those are 'external' I was talking about 'internal' ..... yes it is addictive.

No, I don't think it is available in the UK anymore, hence mentioning RS50...

Yes. sorry I missed that - I though RS50 was more for the 30 and larger callibers RS Charts

Varget (I believe RS50 is pretty close to it) is another go to powder here in the US for 75gr bullets in the .223.

I don't think Vargent is 'REACH' (Regulation (EC) 1907/2006 concerning the Registration, Evaluation, Authorisation, and restriction of CHemicals) compliant so (if it is available) it won''t be for long ...

Working up a load with a powder you may not be able to find again is not ideal ...

Hi varmlr

when I first got the rifle about 5 years ago I took it up the road to the tunnel range to set it up and had a box of both 60gr and 62gr bullets and it was spitting them all over a4 piece of paper but as soon as I put 69gr in it tightened right up and with 75gr was cloverleaf which was happy days until I realised how expensive they are lol. The distance usually is 300 or 600 yards and only shot out to 1000 yards with it because my mate was trying the same with his 223 😁. I have thought about reloading for some time now and with not working at the minute have ordered a load of reloading gear 😀 and was amazed at all the different powders available !

It's not that the 75's were (exclusively) right for the rifle, it was that the combination of the load and the 62 and the 69gr bullets weren't. Once you find a node that results in the bullet leaving the barrel when it's not flapping about you will get tight groups from any weight of bullet (unless it won't stabilise with the twist). That's the whole point of reloading, finding that sweet spot where all the ducks line up.

Lots of different powders, yes. They all have a specific characteristic but the key is to find one that generates enough pressure to get the bullet moving and exiting the barrel safely and at a speed that meets the needs/requirements of why you pulled the trigger in the first place.

Slow burning powders suit larger diameter chambers longer barrels, and heavier bullets than fast burning powders ..... (a bit simple but true).

Are you using an internal ballistics tool (like GRT or QL) to look at this in more detail ? - it's not neccesary but I find it quite heplful. All in all the powder/bullet manufacturers have it right. If you get the powders they reccomend and 'work up a load' you will get superior accuracy than from any 'ready rolled' ammunition', and it's much more satisfying

Hi Miki

yes big lump for a 223 but I get v bulls at 600 yards and have even hit a gong at 1000 yards lol.

The rifle doesn't stabilise 60 gr bullets or less I think that's more for a rifle with a 1 -12 twist

Ive been looking on the viht site today and it recommends the n540 for those bullet weights so hopefully happy days ! 

Excellent. The twist rate nominally effects the stability relative to length. Obviously the heavier the bullet is for a given cross section/diameter the longer it is. 1:12 has problems with the longer but I don't think the faster twist should effect a shorter, in the same way (more reading req  🤔)

There is a point where the higher weight and BC will give more distance but I don't think the bullet is still supersonic over more than 600 so surely must be tumbling at that range ?

Hi Miki

I've got the Hornady 10th reloading manual and its got 17 different powders on 75g bullets 😮.

There's a couple of gun shops near me selling different powders i.e vhitavouri, alliant, Hodgdon and reload Swiss 

@ontoproofer excellent of the book. The advice @Deker gives is good tpp (and based on real experience, wheras I don't have a rifle chambered in .223) RL52 (Reload Swiss) is a good modern powder. the nearest equivalent in Vhit is N540 *

A 75gr bullet is a heavy lump for a .223 size case isn't it ? Why that big ? A 55/60-gr would give you more speed and a flatter trajectory (and a bit less recoil too i'd imagine).  A 55 should get around  or above 3300fps where the 75 is crawling along (haha) @2800(ish) you should get a wider choice of powders for the lighter/smaller bullet too.

Have you tried any other bullets ?

*REF: Burn rate link

Learn the right names for the components and buy a reloading manual  👍

A load needs to be developed, there is a lot of information of where to start on the powder manufacturers websites, Vhitavouri for example ,, https://www.vihtavuori.com/reloading-data/rifle-reloading/?cartridge=7 n

They show loads for 3 different 75gr bullets, with N140 and N540 being common to all. Your rifle is slightly different from anyone elses so thier loads may no be ideal in yours, they may even be dangerous. What powders can you get localy ?

I have a new (unopened) bag of Winchester .22-250 cal brass surplus to my needs.

£40 delivered

I use Loctite 222 (the purple variety) on mine as it allows the screws to be removed without damaging the head or requiring heat.
