I'm fairly new to the 6br, and have questions. I'll start with the rifle, the one I have started life as an XR 100 the rem. chamber was redone, the bolt was redone and a sako extractor added. It has a Maclennan barrell that's 30" with a 1-8" tw. Its cut so that I don't have to turn brass,.268" I think).
After breaking it in with the Diamond line ammo I've been loading as per suggested and tried 31gr. of varget behind a 107gr SMK. They shoot well but I find that the bolt more often than not is tough to lift to eject the spent ones. The bullets are loaded far enough out to just touch the lands so that closing the bolt you "just" start to feel pressure closing the bolt.
I backed the load off to 30 gr.of Varget and although they still shoot dynamite I still get a bolt that's tough to lift.
I've tried seating the bullets a few thou deeper too.
The brass is not showing any obvious signs of pressure/stress and i'm looking for suggestions.
I'm reading of people loading in excess of 31 gr. of varget and doing ok
I'm reading of people loading 20 thou short of the lands and people loading into the lands and doing ok
I was wondering if maybe the shoulder of the cartridge is causing the troubles ?
Would love some ideas, and as i'm fairly new to the extreme end of precision loading, please use small words, laff.
