Made another range trip today, shot the .405 Winchester Target, .338-06 Ultra, SS 30-06 and .22-250 Fluted Ultra Varmint.
The .405 just doesn’t like the 350gr XFB, they aren’t accurate and velocity is way below what would be expected, using Fred’s suggested loads from QL, I got at least 200fps less velocity and shotgun patterns, so that ends the quest for using those bullets.
The 300gr Hornady SP was a different matter, those shoot great, typical H&R accuracy, at 100yds 2 shots touching or closer and the 3rd a bit of a flyer when shot back to back, if I let it cool after the 2nd shot, they'd all be together. Best group was .675" with the first 2 almost in one hole using 56.5gr of Benchmark, runner up was 1.195" w/56grs. Velocity was right at 2420fps, 57gr caused them to stick just enough that the ejector wouldn’t kick em out, in fact the first one that stuck, ejected while I was sticking a rod in the muzzle. The primers also started flattening a little.
Shot the stainless .30-06 that I bought from Kufford last year, using 150gr Fusion ammo, was really excited when the first 2 rounds were almost touching and velocity was right at 3000fps, but the 3rd shot was almost 2" low and velocity dropped to 2940fps, if the velocity was consistent, they’d be great shooters, but that was the experience I got, most were right at 2999 to 3010 fps, but several were 50-60fps slower, I have a few left, gonna weight em and see if I can find a weight difference, dunno what’s up with that, maybe just a bad batch.
Shot the .22-250 with Rem UMC 50gr JHP factory ammo, my floating job on the forend seemed to make a difference, but the ammo just doesn’t shoot good, velocity was good at around 3800fps, but again inconsistent, some were considerably less than that, when the velocity was closer, they grouped good. I’ll have to work up some 50gr Vmax loads before another range trip.
Also shot some 200gr CT Ballistic Silvertips and BL-C2 in the .338-06, best accuracy was w/56gr at 2675fps with 2 shots almost in the same hole and 3rd about an inch away, but velocity was close, maybe I pulled that one or the barrel was just too hot, 56.5grs put 2 holes touching and another away from the group for a 1.1” group, again velocity was consistent at about 2690fps. Even hotter loads provided acceptable accuracy at about 1½” with 58.5gr at 2875fps, which is pretty good considering the barrel is throated for 250gr bullets. Cases started sticking at 58.5gr even tho primers looked good.
Had a bit of excitement when I was shooting the .30-06, velocity had been running 2940-3010fps, then one shot was 3249fps!!! WHAT!!!! Couldn’t figure that one out, brass ejected fine, looked good, and this was factory ammo!! Then I noticed one of the sky screens on the chrono had popped off the rod and was hanging off to one side!! Put it back together at the next cease fire, and I was back in business.
