Believe it or not, standard old Remington Core Lokt shoots well in my BLR 7-08. Keep in mind that the skinny barrel of the BLR heats up fast...like after 3 or 4 shots and groups open up quick. I take notes at the range as to where my first and second shots from a cold barrel hit and then put the rifle away while I shoot rimfire or another rifle for a while. The first shot from a cold barrel is what counts when you're in the woods anyway. Take notice of the first 2 shots and then (have fun and) realize if you want to shoot a box of ammo or two in your BLR, you're not going to set accuracy records.
