Well, I had a few hours to kill, and wanted to see what the 264WM would do with the 130gr AB's and RL22. It shot pretty well. I will say this, I was way to jazzed up on coffee to be shooting super groups, and had about three groups with 2 touching and once I tried to settle the 3rd one it, I boned it up. Here are some results
63gr 3026-3052-3054
64gr 3130-3117-3093
65gr 3244 - 3273 - 3272 (barrel was still too warm, didn't allow it to cool completely)
66gr - forgot to turn the chrono on and just had a complete brain fart during that session. Group was about like the others, with me pulling the third!.
67gr 3379-3362-3408 (first two were fine, third left an ejector mark on case head and had a slightly sticky bolt lift)
Now, the Whelen, all the groups were about the same size with RL15 and the 250gr PT's. Some were in the 1.25" range, but all respectable for this combo for me.
57gr 2479-2476-2477
58gr 2496-2505-2505 (again, pulled the 3rd. I get too happy with myself sometimes)
59gr 2574-2575-2576 (decent group, but most of it was in the wood)
60gr 2673-2671-2669
That last group at 60gr's came together well for me. There is no measurable or visual differences in case head expansion or primer looks. It seems pretty darned good. I am waiting to see some data from QL for projected PSI, but I am think it is still a safe load. Not that I am worried too awfully much about them, everything checks out as far as I can measure. I am just in denial about the 35 Whelen pushing those 250's like that. Alliant has data with the 250gr Spire Point to 59.5 and they state 48,000CUP. That is still kinda mild, so that is why I pushed a little harder. In MY rifle, they seem to be good to go. Ambient temp was 75* here in Northern Va, so it seems okay. I will retest some more, but I have been shooting about the same exact load with RL15/CCI250's/RP cases and 250gr Speer Hot Cors for awhile and have nearly the same results. Kinda makes me wonder why I have a 338WM! Anyhow, I figured you all would want a look at this.
Looking forward to dropping back to 66.5gr of RL22 in the 264WM and seeing how it does. I would think it should be good. The rifle is shooting fine. All those 2 in's and 1 outs can be attributed to me being a nut job. It does take that barrel a long time to cool, but whew man, 130gr AB's at 3300 seems pretty darned good. I can really see any need for more, and with some tuning it should turn in some proper groups shortly. I have to really put this rifle to the side and let it cool. I shoot three shots as fast as I can cycle the bolt and aim back in. It is the way I shoot groups. I know I could probably do better letting it completely cool between each round, but I am looking for hunting loads, and I want to know what the rifle is capable of. Overall, I am very pleased with the 264WM. It is a baby to shoot. Plus, it is fast. Can't imagine much walking away from one of the 130gr AB's. Should be a deadly combo. Scotty
