I have noticed that these 300 tsx are coming out much slower than other 300g bullets I have with the same powder charge. I want about 2400 and am getting about 2100.
Am using 72g of RL15. This is already a compressed load (these bullets are freaking long). I was thinking of trying IMR4064 (faster powder).
Anyone else had this problem? Any suggestions?
I'm using 79.6 gr. of RL 19 for 2,592 fps. from both my Ruger M77 and Win. pre-64 .375 H&H's with the 300 gr. Barnes TSX and Banded Solids. Most accurate bullets I have found. Using 67.4 gr. of IMR-4064 gives me 2,545 fps. Lawdog
