Hi Guys

What are people using to shoot this at 300 - 900 m's.

Given the T4 was produced in the days when barrels were designed and built for the 144 gr bullet; a good compromise is to use the 150 gr SMK with 43.9 or 44 grs of N140.
I adopted this load after the scare mongering tactics of the NRA regarding using 155 gr in No.4 actions and their advice about getting No.4's re-proofed to 20 tons.

I have "held the black" with this load at 1000 yards on Stickledown in the past.

Strangely brown; what are your velocities out of the muzzle with that load. If 1000 and still in the black, one would assume a very fast moving projectile

[Strangely Brown]

I don't have a chrono speckles so I cant answer that one I'm afraid.
All I can tell you is that was a favourite Bisley load before the switch to 155 gr bullets and the advent of rifles with forward locking lugs.

As an aside I had a long conversation with Ted Molyneux (shot for GB in his day) who looks after the NRA museum at Bisley; he recalls a friend going over to Scandinavia in the early 1970's and importing a quantity of Raufoss 7.62mmx51 (144 gr) ammunition.
The word was that it was supposedly very good.
On the ammunition's first outing the scores were higher then they could ever have imagined, it then slowly dawned on them how poor the Radway Green was that they were going to have to shoot the next Imperial meeting with!

I just ran the VV N140 - 44 gn load through Quickload 3.9 I have, it gives a projected velocity of 2,701Fps out of a 25.2" Brl with a chamber pressure of 44,657Psi (Div by 2,240) or 19.936 Tons (The imperial ton is 2,240lbs the USA has the Short Ton which is 2,000lbs hence it is good to know both weights when calculating stuff makes a huge difference.) It is only a guide but the load is getting there.

Hi Mick
Are the NRA still giving this advice re the 155gr and I take it anything above.

Hi Guys

On looking at my T4 it seems to be stamped T20 on the reciever. does this mean it was proofed at the higher pressure to comply with NRA advice. There seem to be no other markings on the barrel other than words Parker Hale LTD Birmingham England and Model T4 7.62 NATO

Attachment 87454

As well as the standard "BNP" for nitro proof I believe "SP" is the Birmingham Proof House mark for "Special Definitive Proof" and the T20 is twenty tons. My Parker Hale M82 has similar proof marks.
