Re: Help with .408 CheyTac & RL25
Im using 400 grain moly coated lehigh projectiles and couldnt find any data so i had to go through the expense of load n fire through chronograph. I just started 3 weeks ago and my tightest group so far is one and five eights inches at 400 yards thats what im zeroed at. I wanted to use 50 bmg powder and did till i had a super compressed load at 150 grains and was getting an average of 2900 fps with no pressure signs at all. I went to the next available powder which is retumbo and im at 139 grains with a bit of crater on the primer, thats where the one and five eights group came in. Im still playing with the load but my shoulder has taken an ass whooping so im gonna lay off for a couple days. My rifle was built locally by a good friend of mine, its a stiller action with a 1-13 lilja barrel and a jewel trigger, i think i will try a 1-14 next time.
