Thread: Neck Tension Issue... I think

G'day team,

I've been discovering the highs and lows of reloading over the last 12 months or so.

My 7mmRM shoots pretty well. Recently I've been trying combinations of AR2217 and 162g ELD-X. Long story short, about 6 months ago I was doing some load development and had issues with excessive pressure when I was not expecting it so had about 30 bullets to "pull".

I pulled them all last night using the RCBS hammer thing. After a few, I noticed that about 1/3 of them were very easy to pull and the rest were very difficult. I'm looking for any thoughts on why this might happen and whether this could be the cause of the unexpected excessive pressure?

The bullets I pulled were loaded over two separate sessions with the same dies. I might have fiddled with the dies in between (it was a few months ago and I can't actually remember) but don't think I would have done anything too silly? Would I? All were loaded with twice fired Norma brass. All seated 0.020" off lands. All cases trimmed to whatever the right spec is. None were compressed loads. I can't think of any other variables off the top of my head? Oh, and no points for who can guess which of the projectiles below was harder to pull.

Thanks for any help in advance.

Elliott
