So I got a remage prefit in 223rem with a match chamber. Criterion said this chamber was setup to be ideal for 80gr bullets which is what I was planning on shooting. Got it in and checked oal with 80.5gr bergers and it seemed REALLY short throated for a barrel intended for a bolt gun. Talked to a gunsmith friend of mine and he said he would rethroat it deeper with his reamer setup for 77gr tmk. Got it back and checked OAL again and it still seems really short. The first pic is with the bearing surface/boat tail junction seated right at the neck/shoulder junction like most cartridges are setup. The second picture is seated .020" off the lands. It measures out to be 1.820" base to ogive seated .020" off the lands. I've got PLENTY of room left in my accurate mag for more length and feel like I could get more speed if the bullet wasnt taking up so much case volume being seated so deep. Is there a reason why .223 reamers seem to be setup so short?
