Well I learned a valuable lesson last week, I'm at the range testing loads and my loads wantedbto lock my bolt down, to the extent of having to smack bolt handle with palm sharply to extract fire cases....What the heck? And yhe fired cases had zero soot around them like normal....All this with the manuals minimum charge..?
Traced all my steps, and figured out where I went wrong. Some of my brass for one reason or another wouldn't chamber easily, so I took measurements of the length, shoulder ,so on, and determined I had not set shoulder back any, or enough for easy feeding.
I then took decapping pin and expander out of my die and lubed up the primered cases and set the shoulders back just a few thousands, in that process I must have crushed my shoulders a tad and then the bullet tension was extreme, and so when I seated those long bullets it not only crushed the shoulders a tad more it created more runout in my necks.....so what I had was cartridges that werr tight going in, they also didnt want to extract.
I couldnt salvage twenty pieces of primed brass, but also when at the range we would have one or two flyers that were 2"'s out of group causing a lot of head scratchin,,,, and then it hit me that the pressures were probably obscene with just minimal powder charge...
Problem solved, and a valuable learning process for myself......
Excuse me while I DIG MY HEAD FROM THE CAVITY!!!
