I am loading for an old Ruger M77 270 and a Ruger 308 American Predator 22" barrel.
1) Can someone tell me what factory OAL is for 270 130gr Rem PSP and the 308 150gr PSP?
2) I tried shooting both the other day. 270 130gr Rem with 54gr IMR 4831. Got about 2" group at 50yds. OAL 3.284"
3) 270 140gr Sierra Spitzer BT 54 and 55gr IMR 4831. OAL 3.308". Again about 2" at 50yds
This Ruger 270 has probably 1500-2000 rounds shot. Do you think the barrel is worn out?
4) Ruger 308 150gr Rem PSP. 44 and 45 gr IMR 4064. Again about 2" at 50yds. OAL 2.752"
5) Ruger 308 150gr Sierra Boattail Spitzer. RL-15 44gr and 45gr. Did get about 1" with 44gr. OAL 2.778"
See different amounts RL15 for 308 150gr bullets for max loads??
Since reloading supplies are hard to get just trying to come up with a load that can get 2" at 100yds. Any advice on OAL or powder changes in these 3 powders I have would be great. Thanks in advance for any help...Tom
