Question for the pros. I’m a newbie reloader. I developed a load using 56g of H4350/fed brass/ rem primers and 180g sp. I started seeing pressure signs between 56.8-57.2. My best groups were at 56.8 but I’d get the occasional smiley face from the bolt on some brass depending on my seating depth. Went down to 55gr of h4350 and found a decent seating node. Just recently purchased some Nosler brass and made a few to test using 55gr and had pressure signs. Backed it down to 54 and my velocities with 54gr in Nosler brass match velocities of 56.8 gr in federal brass. Same seating depth. Is that common?
