6.5 Sin

I haven't posted on here for a while but I have done some testing. so far I am getting 36-3700 fps with 140gr bullet and 3550fps with the 160gr Matrix bullet. I will get doing a lot more testing with the 160gr before I go back to the lighter stuff. my original test barrel is a 30", I am also testing a 24" too.

What Powder?

No more updates, winter has hit hard and we have had many days of -10 and colder temps.

Powder was us 869. I am going to try some 50bmg on the next loads.

That sucks. We are in heaven with yote and wolf hunting here. Lots of great shooting opportunities too. Downed a dog at 730 and tried for 2 at 1300. First was a miss but second we felt was a hit. I didn't feel like hiking down one side of the mountain to the other to check. I will next time though. Been bugging me. LOL.

You might try some RL33 with the 160's... very close to 50 BMG in burn rate and it's been producing great velocities and accuracy.
