[QUOTE="orkan, post: 2635848, member: 25377"] Ok, it's been a long while since I've had to work this hard at something. I'm either going to have to throw in the towel, or I'm going to have to start trying some drastic deviations from the norm. I have a few more wild ideas I'm going to try next session... as I'm not quite ready to give up yet. [img]https://i.imgur.com/9c3m9RTh.jpg[/img] Here's the last 112rnds of trying to get load work done on the 70gr HH's. [img]https://i.imgur.com/gUgANeTh.jpg[/img] The bottom row on the top target is basically as consistent as I've been able to get with them so far. About the time I think I've locked into something good, it turns out to not be repeatable. POI stays fairly constant, but all attempts to get smaller performance have been thwarted. It remains very easy to get 1/2 to 5/8 MOA... but seemingly impossible to get better than that. That pair of targets represents 2 separate powders, over 5 grains of charge weight, and 125 thousandths of seating depth variation on both powders. Varget didn't work. H1000 didn't work. H4350 didn't work. RL26 didn't work. VV540 didn't work. VV560 didn't work. RL22 didn't work. Crimping didn't matter. They don't care about velocity or jump. Both the 52HH's and 70HH's behaved the same way. There's so many unknowns. Do Hammers just hate my chamber? Do they hate Benchmark barrels? Do they require a special twist or land/groove configuration? Is there something inherent in the bullets designs that are causing this? Keep in mind, Hammer isn't going around claiming sub 1/2 MOA. (at least not that I've seen) Today, as a control... I went back to my trusty 80gr bergers and did a typical load dev session with them. The bottom part of the target is zeroing, and a quick confirmation of my two pet charge weights of H1000. Then a quick glance at seating depth options on the top row, I selected where I thought I should be... and fired two confirmation groups. Suffice it to say, this is just what I've come to expect from my 22 creeds. Sub-1/4 MOA is the norm with rifles configured my way with my reamers. [img]https://i.imgur.com/Y6FSaIOh.jpg[/img] Frankly, I think I could have tightened it up even more with H4350. I've got some powders which are completely outside the norm for the 22 creed. I'm going to move into them next and see what happens. I have exactly 517 rounds on this barrel now... and I can't help feeling that I've accomplished nothing.
