[QUOTE="Long Time Long Ranger, post: 529917, member: 505"] Shot a few groups this morning at 400, 600 and 1000 yards with a different seating depth. Seated down to 3.97" coal with 128.5 grains H-870 and got excellent results. Two 1000 yard groups gave 7.61 and 8.39". This load averaged 3527 fps for the ten shots with eight fps spread. The BC is definitely above the listed .64. I gave preliminary tests earlier but now have sufficient data to say the bc is over the listed .64. I have tested these bullets in two rifles with the wby freebore. This one and my 340 wby. With both they like the bullets seated way down in there .2" or further deeper than recomended. With my standard chambers they seem to like being seated right at the recomended depth. I just load them where they shoot best and I can't argue these hunting weight rifles shooting these kind of groups. I am loading up some of the 252 grain bullets this evening in a couple big 338's and see what they do. They are beautiful bullets for sure. Probably try them in the 338 Lapua, 338-300 RUM and another 338-378 wby. [/QUOTE]
