Hi,
Anyone got reload data for a 1971 vintage Envoy in 7.62x51 please, thats not too hot for the old girl. Looking to use 150gr SMK's with Sampson brass, and would like to use H4895 powder which is my powder of choice.
Been looking at loads for .308 not sure if they are ok to use....
Thanks.

As long as it has a 20Ton proof use your normal loads. I use my standard .308 target Load using a 155 SMK. They are not as fragile as you think. RWS/RUAG shoots really well through them.

Hi Tackb.
Been looking for some. Know of any out there.
Thanks Steve E.
Not sure about the 20T proof only had a quick look over it, thought it was 19T proof..Being serviced as we speak.

crikey no i'm afraid not , i gave tons of it away over the years ! the only stuff i get now really is 1 in 1 tracer/ball which i split up because i only want the tracer , if i had any ball left you could have it gratis !
I will ask around for you though?

Hi bnz41
The range table in the 1975 sniper pocket book for the L42a1 gives a time of flight of 0.12 seconds for 100 meters. so disatance / time = 833.3 meters per sec or 2732 fps. It does not give bullet weight it just says 7.62 I assume it was 147 grn.

The key to this is a suitable powder, a chronograph, a bit of commonsense and an incremental approach. Your rifle is perfectly safe with modern factory ammunition and you should be able to reproduce that performance with a little development.
Armed with the above, start with a light load (40gr of N140? - Steve E or somebody that knows help me here), see what velocity you get, and work up gently to a sensible figure. Check at each increment for signs of overpressure. To give you a guide, RUAG 155 (SMK bullet) as issued by the NRA has a mean MV of 2920 ft/sec and achieves that with a max average working pressure of 3650 Bar. 20 Ton proof is the equivalent of MAWP of 4150 Bar.
I do not pretend to be an expert in this. I understand just enough of the basics to hold a conversation about the safety aspects of reloading. I comment only because there are, regrettably, too many incidents on UK ranges that stem from an unthinking approach to handloading.
If the above is not clear, may I suggest, with the greatest respect, that a reloading course would be appropriate?

Just come across this, Iain I do think that is a tad uncalled for I think Neil has more than demonstrated here that he is a responsible handloader, if he wasn't he wouldn't have started the post.
As far as I can see the advice to work up loads is sound and no doubt Neil knows that it looks to me as though he was just looking for people who have been there no need to belittle that.
As far as I recall the proof marks on coverted No4 actions were 19 tons it should be on the bolt head. We should all be very carefull when posting data here and ensure it is correct, ideally we should mention the source which should be a printed one. It works in my rifle isn't really good enough.
