Working on building a hunting load from my Savage 7mm-08. I typically shoot 139gr sst's with IMR 4064. I wanted to jump up to the 150gr ELDx bullet. I believe I have a 1:11 twist which is on the slow end for this built. Can I use a powder like IMR 4350 to get my velocity up to hopefully help stabilize the bullet or will that not help? Other powders recommendations are welcome!
