I just got into reloading and Im really getting into the fine details and precision aspect of it all. It appeals to a certain aspect of my OCD.
Anyays, I just picked up a GAP 10 in 6 Creedmoor and was putting some rounds together for it last night. I was checking chambering because the bullet I am using (Berger Hybrids) George says may need feed well.
Its then that I realize how tough a gasser is on ammo. As the BCG slams forward and rams the round into place, I noticed how hard the bullet tip is slamming against the feed ramp. Ive never paid attention before because any precision rifle Ive owned was a bolt gun and on my AR's I didnt care.
So I did a little experiment. I loaded up 10 pieces of brass....basically blanks with no primers and powder. I was super precise with seating depth and concentricity. Then I would pull the bolt back and let it slam forward but I would eject it very slowly to ensure that any change in bullet depth or concentricty was done on the ride forward, since the ride out was irrelevant.
I was a little surprised after rechecking the ammo how much everything has changed. Bullet depth was at least 2-3 thou deeper, sometimes more.....but concentricity was way off. Not surprising considering that the bullet tip is what is guiding the round into the ramp.
So it got me thinking. All the mess and attention to details that reloaders go through to get the most accuracy....does it really matter that much?
I was watching GAPs video of Tyler shooting better than a 1/2 inch group at 1000 yards with the same rifle.
How important can all that be when theres no doubt a gas gun unsettles all the work you do making sure your bullet is perfectly seated but it still shoots lights out?
