[QUOTE="RT2506, post: 2025353, member: 10178"] It is not necessary to crimp if you are getting proper neck tension. Go to the Grendel forum and join and do some reading on the subject. I have done it both ways and see no difference in accuracy or function except with one particular bullet. It was the Sierra 100 gr HP. It has a BIG HP and the nose is almost flat. I did not crimp them and they wanted to nose dive into the feed ramp and jam and it drove the bullet back into the cases some. I did not try them crimped because I was just trying to find something that would shoot good in that particular rife. When I built both of my Grendel's (long story of why I built two) I was looking for a bullet to deer hunt with and my time was limited to get that done with the trouble I had, (which is part of the long story). Once I got things right with the rifles I just worked with Hornady 123 SST, 120 Sierra Pro Hunter and 120 Speer Gold Dot. The 123 SST just would not shoot well in either of my rifles which have different barrel makes no matter what load combo I tried. They shoot sub MOA with the other two bullets and IMR 8208. At present I do use what I call a medium Lee Factory Crimp on my hunting ammo just because it makes me feel good. LOL If you are going to crimp do get the Lee Factory Crimp Die. [/QUOTE]
