[QUOTE="itchytriggerfinger, post: 2050704, member: 24854"] Rsnell : The Ammo was Federal power shock 180 gr soft pt. I have not shot reloads. I cannot chamber sized brass that has not been fired in this chamber. I did pull a bullet and weighed the powder charge at 69.0 grains but not have identified the powder. Rick: spoke to the builder, he did not seemed concerned, he did indicate that it is a short throat and it was like a “ race car”. He did offer to rethroat it but said I would sacrifice accuracy. He basically said I should be working up a load starting with virgin brass. Which is exactly what I would do IF I COULD FIND ANY...lol I thought the next best thing was to break it in using commercial Ammo and then reloading it. Casual: I cleaned the chamber with alcohol after every cleaning so I am sure that residual solvent or oil is not an issue. As far as seating depth, I am at least 35 thousand off the lands. What really has me twisted is why, of the same lot of ammo and almost identical conditions were the first ten shots fine and the next 20 were not? What could have changed? I mean, I realize it is a very gradual process but as the round count increases, the throat erodes slightly and that should alleviate pressure somewhat. Which makes me think, it should have been the other way around, showing pressure signs with the first shots and lessening with the subsequent shots. Or am I missing something? Below are pics of the first ten cases fired. [/QUOTE]
