If you are a coil cutter, than that is what you want.
I bought a M586 off a guy who shot 40,000+ rounds of 148's 2.7 grains Bullseye and Federal primers. He was a PPC competitor.
The action was wonderfully smooth and light largely due to a weak mainspring. That weak mainspring caused squibs and misfires in cold weather with WSP and AA#9. Changing to a new factory mainspring fixed that, but lost the light action. It still is very smooth.
Federal primers are good primers in pistols and bolt guns. I had two out of battery slamfires with the things in M1 Garands, one blew the back of the receiver off in my face.
If you guessed, I don't use them in Gas Guns anymore.
