[QUOTE="el matador, post: 1314458, member: 12193"] Its not so much the length of the bullet you need to worry about, but the length of the ogive. Anything shorter than .500" will work without issues and you may be able to fudge another .050 or so. Much longer than that and you'll be seating the ogive down into the neck. I have used Hornady 75 grain BTHPs and they work fine. Most bullets in the 68-70 grain range will also work well. The 75 grain A-Max is too long (ogive is about .585"). I loaded some of these for my AR but had to single feed them. I pulled some of the polymer tips out with pliers, leaving a hole in the tip, so I refer to them as A - Hole - Max bullets. Here is a sheet that Len posted a while back with measurements for Berger bullets: [U][URL]http://www.longrangehunting.com/forums/f19/berger-bullets-tech-data-list-39871/[/URL][/U] You can calculate the ogive length by subtracting "base to ogive" from overall length.
