I did this last minute because i noticed there were 2-3 that didnt want to chamber correctly. The original COAL had large recoil but wasn't painful. Today even the starting point i felt a donkey kick me. Ask the range officer who was watching me if he could try it out to see if its just me being a ***** but he said "no way, aint shooting it. i can tell from here that load is too hot".
Using lyman 49 for a 410gr pc cast bullet i started at 45gr of varget, 46, 48, 49, 50, 51, 52, 53, 54, 55. Tapped out at 48, shot up to 52 on the sled then decided ill just pull the rest. there was no sense in me just shooting off a sled and going higher up when i wouldn't dare shoot them off hand regardless of how accurate they looked on the sled. First time i tested these out at the longer coal, i was able to shoot up to 55gr. I did however find 46gr to group all in the same hole with the shorter length so thats the only good news i took home from that if i ever want a really hot and accurate load.
Now im in need of some advice on which direction i should take this load development. Should i keep the short high pressured COAL but scale it down to 38gr-46gr or go back to the original but seat deeper maybe 0.010"?
