I am not sure if it is my measurement tools, my technique or my loading tools, dies etc... But i am having a tough time getting consistent shoulder bump in .308 and .270 Win with Starline Brass. One case will barely bump at all, and the next one will be oversized. It is very hard to set up a die with such erratic numbers.
I know about neck lube and all this stuff, and have for a very long time.
Up until i started loading .308 and .270 my experience consisted only of 223 REM, 45-70, 30-30 and various common pistol calibers. Processes are still under investigation, and the brass may not be the problem?
If a guy is looking for brass, they have been the only game in town for a couple years now more or less.
I love the company. Glad they exist and make all these cool old-school calibers still.
I will continue to buy lots of brass from them.
