One of the main reasons grauhanin for cleaning shop is the multiple ammo I was shooting out of the multiple of guns,consistently inconsistent by bouncing around.that being said,I had a brick of pistol match that shot a .6 3 out of 6 at a hundred yards in the 1761,but the next lot of it,nope.and couldn't find that original lot number anywhere. I think in canada it is hard to buy a similar lot number after you find one your gun likes,more times then not you can't even get the same brand because it is sold out.
