My brother called last night and said he screwed up bad. His accurate load for the 6.5 creed is 41.2 of IMR 4350 and the 143 ELD. He some how loaded 50 with 42 grains and was ready to pull them down and I said wait until I ask some questions.
All right. He was using Horn brass for his Accurate load and we found some damn good Nosler brass. The nosler brass is what he loaded with 42 grains. He stopped at 41.2 in the horn brass, because it will plain out make one hole at 50 yards. 42 grains is max by some books or over max by others, for the 143 or 140 to 143.
I looked about W.C. and it changes for different weights of bullets. How in the hell does inches of water change in the same piece of brass,,, by using a 100 or 143 grain bullet? Nosler has data for the 140 to 142 grain bullet and W.C. is 46.8
The 100 grain bullet W.C. is 50.9
Im lost and don't understand at all. I thought pieces of good brass held the same water column, out of the same lot. Mil brass is thicker, therefor you reduce the load by say, 10 percent when starting. All brands of cases are different and 42 grains of powder, might not be hot in the Nosler brass. This is what im trying to figure out, but not having any luck yet. I told him to just shoot one and see if there is pressure signs, and if not,,, shoot a group to see if the 42 is as good or worse. Its not like he went way beyond on the charge and told me that the 41.2 ,,, has no pressure signs at all.
Then again, he is using a differ brand of brass and might be hot as hell. Learn me please and if it was mine,,, id shoot one in a heart beat,,, to see if pressures was ok.
