For perspective mine is 55.0 with 4831sc and I'm at 2830 in 90 degree weather. I started seeing pressure(hard bolt lift, cratering primers) at 55.6 on the 90+ days.
Going to get my 284 F-Class rifle next week. I'd like to get up and running for a Palma Shoot this weekend. Just curious what barrel length and the COAL most people are using for the above loads. I ran these through Quickload and have come up with some high pressures. I assume that the COAL is 3.0 and above.
