Re: Strange load development results
I think I understand what you are saying but am having a hard time trying to reason why I would try a slower powder as opposed to a faster powder in this situation. I have some H1000 (which I read burns slower than RL22) so I guess I could load some up and see what happens. Wapiti you mention 4831, which is actually burns faster than RL22, so maybe I'll try that too. If I can't crack 3200 with a 165 I think I will just move up to a 180.
By the way, I loaded some more tsx's and some NBT's today and confirmed that it is not just the bullet. Both the NBT's and the TSX's increased velocity and grouped quite well right up to 78 grains of RL22 at which point they both started to plateau velocity and the groups opened up a bit. At just under 78 grains both bullets maxed out at about 3125 fps with excellent groups (the tsx's actually out performed the BT's with a .417 group to the BT's .537 @ 100M). So I guess that's the best I can expect from RL22 and my 300WM.
Thanks again for the help. If anything else that I could try comes to mind please let me know........
Hey just one more thing. I am using fed215MG primers for the first time ever - do you think this could be contributing to what is happening?
