[QUOTE="STL_Shooter, post: 25648, member: 888"] Wayne, You were looking for real world data. I shoot a 32" 30 Wolf, a 30 cal variant of the 338 Lapua case, and have a bit of real world experience to share. I get 3280 with 220 MKs with 101 grains of H50BMG. Best accuracy, however, is only 3/8 MOA. I was going to use the 240 MKs, but have not for a few reasons. The ogive to base measurements, weight, and jacket uniformity (length, dings, dents, dimples) of the MKs I've had are, shall we say, all over the place. To shoot the 1/3 to 1/4 MOA my 30 Wolf is capable of - I have found too much variation in the MKs, and end up with too many "uh oh" piles when sorting the bullets. I think I'm pretty well set on these 210 JLKs. Their BC, velocity and uniformity advantages over anything I've seen from Sierra are just too much to pass up. Now, I've petitioned Hornady for a heavier AMax (my Wolf can throw 5 of the 178s into a quarter minute at 600 yards at a muzzle velocity of 3470 fps) but Steve tells me there's not enough demand for him to make them... If you want more detail, just email me... [/QUOTE]
