were you shooting standard loads through this or hot ones? what lb recoil spring?

The comp is the shorter one made to cycle with non major loads. It handles major loads but not as well as the larger comp would have. All of my loads were Winchester white box which are very mild. I tested 50 hst rounds through it to try a slightly hotter load and some gold dot. I didn't notice much of a difference with the slightly hotter loads. I did try some low velocity reloads but after I had a squib. I threw all my reloads away and put up my press and reloading supplies for sale.
I have used 11,12,13 pound recoil springs. I didn't notice much difference personally.

Where exactly are you located? Is this for a gen 3 or gen 4?
