303 British Neck Sizing Die for 30/40 Krag

[concretus]

Well I have some results with some test loads after I backed backed the FL size die 1 1/4 turns. I took this old gal to the range yesterday. Here are the results: All targets were fired from 50yds. I wanted to see what it would do before I pulled the target back. The first photo is using Sierra 150gr .311 bullets, R-P brass, Win LR primer and 36.0 grains of IMR-4895...It measured just under 1 1/4". I used the peep sight flipped up and six-o-clock hold.
The second photo was using Sierra 147gr .311 MK, R-P brass, Win LR primers and 35.ogr of IMR-4895. It measured about 7/8". I had the flip up sight laying down and was aiming at the lower target w/ a six-o-clock hold. Next week I'll go to 100yds.Thanks again for the advise.
