Call Burris....

One member here did a 6XC on a tucky, should be sweet.

Hate reminding folks how often they overpower themselves on deer and such, as my longest deer killswas dumped at 400 yds, Amax, 28.5 Varget, 2850 muzzle, 26" Ruger #1V profile carried out. Kepplinger 8 oz set trigger, shot the smallest 3 shot group ever for me at 330 yds, UNDER 1/2 inch.

I'd go 21" on a #2 but you won't lose 15-30fps losing an inch.

If me, also consider 6mm-6.5x47 Lapooey brass wink Feed Eeze, though bore life is less. Prob push 3K, not that 200 mv diff will be 200 at LR. Either need mils, just a few diff.

Aalf might chime in on a Dasher. Might be the Uber.

Lest one on a budget, Ruger AR 243 9T, hacksaw to 20" and fix trigger with the Boxer technique. 4 Bills. Maybe do some rigging on scope ties for mils.
