[QUOTE="Orange Dust, post: 1495819, member: 92702"] A note to the OP. Once you do pick a bullet for your RUM, do spend some time experimenting with cartridge OAL. There in quite a bit of freebore in a standard chamber. You will be limited to 3.6" OAL with a factory magazine if you want to shoot the gun as a repeater. Every rifle is different. Mine shoots best with 190ABLR @3.820"OAL. 3.84" touches the lands. Before you go the extended magazine route. Try different seating depths. You may or may not determine the difference matters enough to modify the rifle. I couldn't get my particular gun to shoot better than 3/4 groups with anything seated at mag length. Some factory loads shot this well. I found the seating depth before modifying the gun. It normally shoots less than 1/2" with the longer seating. That difference is worth it to me, and the groups are much more consistent. YMMV and chasing little things like this are just part of what makes handloading fun and rewarding. [/QUOTE]
