Through Mr. Uzi's chrono at the last south shoot these pulled 3300+ out of my 20" barrel so 3150 would be about right out of a 14-16" barrel.
my ammo is just old surplus. most says "tw 73" some "c 9 77" some "wcc 69"

anyone reconize those let me know would be interesting since he said hes had the ammo since he bought the rifle in '81. btw never had a misfire or any kind of jam and i just finished off that 2000 rnds today.holy sh** now i have to buy ammo for it... that must suck

yeah im shooting with a 20" 1 in 9 i think.. all the barrel is stamped with is C MP CHROME BORE
