[QUOTE="vancewalker007, post: 1708286, member: 66917"] It's really a toss up between the 2. The real key is to build the rifle so you can hand load long-heavy for caliber bullets to get the best long range performance. That's going to mean having about 3.7 inches in your magazine and having the chamber throated to put the bullet of your choice in the right place in the case when the ogive is in the lands. I would throat it so the bullet base is at or tiny bit ahead of the neck shoulder junction. This will allow I little more powder which translates into a little more velocity without hitting the pressure wall. A mag like the HS Precision DBM will give you plenty of room and provide reliable feeding. If you choose and off the shelf rifle you will likely not have the right twist, throat, or long enough magazine. The factory 7rems are generally setup for 140-160gr bullets and the 300 WMs are setup for 165-200gr bullets. These bullets will not provide the best long range performance in these cartridges.
