I have been reloading pistol for over 10 years,but rifle is new to me.I bought a pre ban AR 15 with a 1/9.Its fine with 55 [email protected] 100,any further than that,no good.So I have been shooting 69 gr.My problem with reloading is when I lube,re-size,and deprime,they are very inconsistant.I have a shell checker,most good,some too short,and some too long.I am using RCBS press,Hornady dies,every thing is locked down and tight,shells are all the same brand,batch,and once fired.When I send my brass over to a friends house to size them,and trim on hid dillion,they come out perfect.It just takes about a month to get them back.
Do I go back to factory,spend a small fortune.
or can I rely on some one to give me a streight answer...HELP
it takes so long for him to get around to do it.
As far as the length goes,when I check the brass with the checker,some are short,and go below the "no go".I can trim all I want,but that doesn't help with the shoulder location.I dont know,I hope you get my question
Do you lube the inside of your case necks? Have you checked your expander ball for smoothness? If you are changing your shoulder or the slope the expander ball/neck friction is most likely the culprit. I have a Hornady die, had to get them to send me another expander ball. The hard chrome that it was plated with was comming off, it was a crappy finnish. The replacement was perfect. I would suggest LEE sizing wax for the inside of your necks. Check your expander ball.
Also, consistent case length is great, essential with match quality [b]or[/b] crimped cartridges. But for most loads without a crimp, it does not matter much. Keep it between trim to length and max, they do just fine.
Cases that are too long are dangerous, can result in high pressures.
