Home Forums Reloading Big Game Rifles 264 Win Mag & 140gr Accubonds

Are you just shooting at 100 yds?? My 264 shoots 1" at 100 yds . It also shoots 1" at 200 yds and at 300 yds. At 400 it goes to 1.375".
I can't explain it other than it is the shooter's fault and not the gun's.
If RL-25 shoots 1MOA at 100 yds go out further and see how it does. I use WC-860 with a Rem 140 Core-Lokt. I never chronoed mine but I am expecting it to be fast. It has a 29.5" Lilja barrel and is throated to seat the bullet out to the second cannelure.

A 264 is too damm hot for 5-shot groups,you are simply burning too much fuel and sending the gas up too small a pipe.My hunch,most throat erosion comes not with the first shot,rather the later ones. Three shot shot groups should give you a good picture.And the extra heat will show up bedding issues as well.That I'm sure about.

You are doing much better than I did with my first 264 barrel.2950f/s was over pressure and the barrel walked,with a good powder I was able to put the targets on top of each other and the holes lined up.

Try Ramshot Magnum, it works well for me when using the 120 gr ttsx, groups are around an inch.
