I'm pretty much doing 215's only when I get above 70 grains of slow burning powder. I'll toss in a wlrm once in a while. You are also shooting a mild charge at dang near a half inch over normal oal. with a rather mild primer; I'd almost expect misfires if it's cold out with that light of a load in an overbore like the stw if a standard primer is used.
What's your load delivering for speed?
Have you de-greased your bolt lately?
Do you have a warmer primer to sub? ( fed 215, cci250, wlrm)
