Tried out the IMR4064 today with my .308. Built a ladder test with some 168grain Hornady ELD Match bullets; also made a ladder test with some 168grain Hornady HPBT Match bullets. Long story short, the ELD’s are absolute junk in my rifle. I’ll post pictures of the targets later. The HPBT’s worked pretty good. Had a decent group with 41.0 grains but not on my actual target because I forgot to reset my zero stop. Lmao.
But then I had 20 rounds loaded with 175 Grain Sierra MatchKings. Everything with them was the same as far as COL and trim length goes. Powder was 41.7 grains. I decided to do a 5 shot group to see how they grouped compared to the 168’s. Let’s just say now that I wish I didn’t waste the powder on the 168grain ladder test. Live and learn. Ended up taking the other 15 rounds I had loaded and moved over to the 1000 yard range. Hit gongs at 500-700-and 1000 yards.
Here’s the paper target from my 5 shot group at 100 yards:
