Well i found this website after a lot of research was hoping some members here might be able to help me out. First ar10 probably 100 rounds down it. Running suppressed just put an adjustable block on there. I figured since I reload for bolt guns I might as well do the same for the ar10. But I ran into some problems.

I started prep on the brass flash hole debur, debur, chamfer. I read on starline that the brass doesn't need resized. I did a couple and both the virgin and re sized chambered. Seated a dummy round which came out to 2.798. Pulled the charging handle back and let go slowly, bolt didn't fully lock up so i pulled it half way back and let it go. Chambered and ejected fine. Some scratches on the ogive but chalked that up to happening when ejecting a couple times.
Any time i let the bolt release go on the mag and dummy round the bullet measures 0.001 longer. Is this going to be a problem? I measured the neck tension and i was about ).003 almost 0.004. I am all ears i just stopped until I could get more information. I really don't want to crimp but will if i have to.
