Greart shooting MD. Keep up the good work.

Here's something to ponder. I noticed he is from Colorado, at what sea level elevation are you approximately? Here in MO I'm roughly at an elevation of 600 feet. Do you think the higher elevations have better groups or worse than those of us at or near sea level? Brains a churning, there may be no difference but I think it would affect it somehow. Not sure how to test other than having him shoot his gun at lower sea level elevations with same loads and distance to see. Cabin fever has got me bad on this one. Those are excellent groups!

im at 7,400 feet. Not sure if the thinner air helps or not. Going out now with some 245 and 295 powerbelts again. Beautiful 60* day

I was just curious, what is the "drill bit" method?

the drill bit is 7/64" and i use it to clean out the flash channel in the breech plug between shots. Primers leave carbon build up in that area and so i just clean that out after each shot so its consistent.
