Radway Green 7.62/51 okay to shoot in Sako TRG-22?

[tschiemer]

is Radway Green surplus okay as practice ammo in a TRG-22? I know it shoots well in HK91s I have had but do not know how”hot” it was loaded and if okay for a precision rifles.

If ok, I will use what I have left but if a problem will shoot Lake City match ammo for practice too.

The worst mil-surp ammo will do in your rifle is be inaccurate unless you get some crappy third world stuff.

I would only be worried about gilding metal jackets or steel case like you would find in cheap Wolf or Tula ammo.

RG, Port, LC, Aussie and South African are good stuff. I think there was good German 7.62x51 but I never tried any.

The thing to know is that it's more like white box ball ammo than FGMM.

You do know that true "gilding metal" is 95% copper and 5% zinc and safe to shoot (when used a bullet jacket) in any rifle

Right?

I stand corrected, I was thinking of copper washed steel jacket ammo and got the terms confused.

Thanks all. As it has been several years since I was shooting w a precision rifle, I want to try to relearn some skills and it is expensive!

If you want to save money, do more dry fire and look for ammo deals. I think PSA had FGMM for $16 or $18 a box not too long ago and it's good enough that you won't have to worry about seeing the accuracy of your ammo instead of you.

Lake City uses copper plated steel jackets

That's a new one on me.

I just read the description of Federal Lake City 7.62*51 and it does say it's a mix of some steel and some copper jacket but all of mine passed the magnet test at the local range.

I've shot a lot more South African and Aussie than LC though and the LC I shot was at the latest early 2000s production and possibly a lot older.

Either way, I would avoid shooting steel jacket in a barrel if I want to preserve it's accuracy life. Just another reason to splurge a little on a case or two of FGMM.

Here is a fascinating article on the history:

“The new M118 ammo used the same 173gr FMJBT (Full Metal Jacket Boat Tail) bullet that the .30-06 M72 Match ammo used. This bullet was manufactured by Lake City and was based on the 1956 International Match bullet. The bullet itself had a lead alloy core (90% lead, 10% antimony) with a gilding metal jacket comprised of 90% copper and 10% zinc. The boattail was a 9 degree taper and was .225″ long. The original specification weight was 173gr but as time progressed and the tooling wore out, that weight began to spread from 172 – 175gr. The claimed ballistic coefficient of the bullet is .494 which was very high for that time period
