Friends rem 308 tactical rifle. We went out and set up my chrono for it and my ar-15 early in the morning before it got hot. We had just completed a few sets of rounds through each rifle when here comes a sheriff to tell that shooting has been suspended till fall because of the fire danger so we packed up and left.
But anyway I loaded the 308 with below the max at 46.4 gr. of TAC. The cases were lake city and have less volume than commercial. avg. of 2921 ES of 10
What is other favorite powders for 308 and 150 168 gr
Oh for AR-15 I was using these new super BC 62 gr HPBT the have lower drag the heavier match bullets. But anyway out of my 20 inch QPQ coated precision wylde .223 match barrel H414 27.4 grains 3126 fps and ES of 8 fps. I also had 27.7 and 28.0 grain loads, but we had to leave before running them through test temp was 77 degrees and 13 % humidity @ 4928 elevation. My friend is into it with his weather station and BC charts calculator.
The Nay sayers told me that H414 is to slow for 223!
Interesting article. It got me to thinking..... I have the old unused drawer on the far bottom of my reloading bench. I never even knew that I still had a couple of tins of Varget. I'm going to sell it all to my buddy with the 308.
He bought 100's of 150, 168, and 175 match type HPBT's
