I recently picked up a browning a bolt in 25 wsm. I bought a box of factory ammo and shot it flalessly aveage groups just under MOA. But 31.00 a box yikes! I picked up some new brass and worked up a load of 42.5 grn. of varget , accurate load averages .5 MOA.
Here comes the problem when I ran out of the new brass I resized the brass and trimmed and reloadec with the same load. While it still shot acurately I had hard bolt lift on extraction I tryied a differant load and got the same results. I pulled the bullets to check my powder charge, no problem there. I went back and loaded a few rounds with new brass and had no problem . What could I be doing wrong. I checked my dhamber it was clean. I tooka look at my sizing die and noticed a spot on the shouolder area at first I thought it was some rust but it wipeout right away as it was a flattened pice of walnut tumbling media could this have caused my problem?
