I'm an old man so I'll ramble on a bit. Ever notice 22 match hollow points. The come in 52 and 53 grain weights. One flat base the other is a boat tail. Let your rifle decide with it likes. Some rifles like a long Bering surface others not so much.
Nosler says the bullet is a 95% of accuracy. Any number of powers will shoot the right bullet accurate.
Also a cheap way to determine length from the lands is to use a dowel rod. Stick a bullet in the lands and run the rod down the barrel and mark at the muzzle with an xacto knife. Remove the bullet and run the rod to the bolt face and mark with knife. Measure with cailipers and subtract .015 or so. The only limit is a short mag box. Hasbeen
