I built a 7 PRC off of the Howa 1500 barreled action last year. I didn't get around to developing handloads for it and just used Hornady's Outfitter with the 160 gr cx this last hunting season. It shot well enough (around 1 moa).
I've now started developing some handloads. I started with H1000. I have a load that looks promising, but I'm testing a couple of powders with the 162 gr ELD-X. I loaded some loads with Magnum powder and shot a few of them. None of them are inside of 3 inch groups. Now, to be fair, I shot them after shooting about 25 rounds out of my rifle with the H1000.
I took 5-10 minute breaks between each 4 round group the whole day. But the Magnum did not want to group. I'm going to reload the same groups and go shoot them with a cool barrel, but I'm wondering if anyone has found a load they liked with Magnum powder. I also have 168 grams of ABLR bullets and 175 grams of gameking bullets to try at some point.
