One thing for sure, you will be shocked at how fast deer die when shot with this caliber!
For a custom, I had a 26" Pac Nor three groove(sendero taper) in a 10T with ZERO freebore, Pac Nor did an excellent job. I shot the 100g at 3850 and the 115's at 3600.
It took a while to stop shooting over stuff. I hunted crows, coyotes, deer, and a few antelope. A crow at 300 did not have a prayer, really good at building up your confidence in your rifle.
I shot R#22 with Fed 215's, worked up accuracy load in less than 20 shots with each bullet. This seems to be a very, very accurate and easy to tune case.
When I got the rifle back from Pac Nor, I went to the range with 5 rounds of 71.0 of R#22 loaded with a 100g Nosler ballistic tip. It took two round to get sighted in after bore sighting. Then shot three rounds of 71.0g, let the barrel cool, then three rounds of 71.5g of R#22, shot a group in the high 2's, then 72.0g, shot a group in the low 3's. Settled on 71.5g at 3850. This is how long the load development took.
Next trip to the range, tried 67g, 67.5g, then 68g of R#22 with the 115g Nosler BT, 67.5-68g both shot around .300 or less at 3600.
How's that for load development?
At 300 yards, groups were in the 1" or a tad less range, with an occasional 5/8" group(wind).
I put a Burris signature 6x24 on the rifle, marked target knobs to 500 to be used as a bean field rifle or a power/gas line rifle. No animal I ever aimed at took more than one shot.
I had a muzzle break on the rifle, and saw every bullet strike on every animal.
Best wishes!
