I too am hoping to draw a CO elk tag for this fall.

I can't remember - does the Firehawk have that ridiculous QLA at the muzzle? I have T/C Triumph Bone Collector. I have been trying to dial in four different conicals (all > 350 grains) with two different powders (90-100 grain loads), different wads, paper-patch combinations, etc. I had hoped to work up a good load, remove the Leupold 2x7 and replace with a Skinner rear peep. After a bunch of powder and probably 80 bullets, the best I could achieve was a NoExcuse .503 bullet with teflon tape wrap - 3 rounds (cleaning between) was still 3" at 75 yards. Not acceptable in my opinion. I dropped off the barrel last night to have the QLA turned off and barrel re-crowned. I am hoping this helps.

This rifle will shoot saboted bullets to <1.5-2 MOA all day at 100 yards.

Good shooting, good hunting and good luck on the draw.
Stay healthy. DJB
