Loaded Berry's 150 gr plated FN into RP .30-30 cases and have seated to the same OAL as I use for Win and Sierra Jacketed FN bullets.
I've loaded and shot this bullet before in my 336 with no problems cycling the action, though I'm convinced that I won't be able to get good accuracy when pushing upwards of 2,000 fps (I know Berry's says to limit the velocity to 1,700 fps on their rifle bullets, but I've been experimenting and trying to see how fast I can push these to avoid re-setting the sights).
So, this last trip out, I'm testing out my first attempt at a trigger job, and used my last 10 loaded Berry's, as I was just testing for function.
Surprisingly, I had problems closing the action the last bit.
Then, had a FTF, with what looked like a light primer strike.
That round had very light rifling marks on the plated bullet.
I think the ogee may have varied on the bullet. If it was "skinny" it may have seated long. If it was fat, it may have contacted the rifling, where others had not.
Could the slightly over long cartridge or the hard closing action, possibly account for the light primer strike?
or ...
did I obviously take to much off of the main spring?
