Quickload Help? 243 Winchester

[soldierofchrist]

If anybody has quickload out there I would appreciate it if you could look up a 243 Winchester with Lapua brass,70 Sierra Blittzkings, Federal 210M Primers, 42.0grs of Varget, COL:2.700" being shot out of 24" barrel with 1-10" twist. Wanted to see approximately what pressures are being run, don't see any pressure signs but would like to check. Appreciate any help.

That is Sierra's top load actually theirs is 41.9 on a 70gr @3400 fps. My quickload prediction is 51421psi (60191 is max) with a weighting factor of 0.45 a 25.35" BBL and with a OBT of 1.069 which is slightly fast so should shoot pretty good in the 24"-26" barrel length range. This is all based on a cartridge capacity of 54grs of H2O. Seating depth .244" 3502 fps. Quickload seems to be optimized for rifles in the 22-27 inch range because it doesn't even get close with a 16" BBL XP-100. My 22Dasher rifle is faster than the predictions and my 22-250 is slower as is my xp100 6BR my XP100 708 and the .243 rifle 24"BBL You are in the top zone so be careful with any increase.
