Sabot looks like you really like to tinker with your projectiles. Ain't nothing wrong with that. Its fun trying to squeeze the most accuracy you can out of your rifles. I do too but no where near the extent you do! About the most I'd do is resize the Lehigh .458"s down to .453" or .451" and see how they shot. I've played with paper patched bullets and found them to be very accurate. But I'm still playing trying to find that mythical bullet that shoots one hole groups. (I know I can do it. Its just all the bullets I tried so far have just too much variance!) LOL
