Chronographed some ammo over a week ago but just now getting around to posting it. Wanted to post results sinse I had some donar ammo from SGF and Stewbaby. Ammo was tested in a 1955 Garand with low barrel and throught errosion. Tempature was in the low 50s.
ES = extreme spread.
Lake City 1969 - Factory 2,491 fps 52 ES on 5 shots
Notes: mild presure signs on primer, still about 50% rounded on primer. Had one light primer strike that fired on second try.
Greek HXP 1962 - Factory 2,662 fps 67 EC on 3 shots
Notes: Lots of pressure signs on primer. primers were flattened to crimp area with very slight cratering on primer
Twin Cities TW 1943 Armor Piercing - Factory 2,672 fps 12 ES on 2 shots
Notes: Lots of pressure signs on primer. primers were flattened to crimp area with very slight cratering on primer
Loaded Ammo in Lake City brass 1969, H4895, Hornady 150 FMJBT, Seat Depth 3.180
# Rds Powder Wt Velocity ES Notes
5 44.0 2469 182 No pressure signs on primer
5 45.0 2571 150 No pressure signs on primer, slightly more flattening
3 46.0 2591 53 Some primer flattening ~ 60%, pressure OK
Thanks again to the ammo donors that made this possible. Doesn't look like I want to shot Greek surplus in my rifle and I will stike to H4895 in the 44.0 - 45.0 range after I check for accuracy.
