Hornady Superformance 58gr ammo supposedly runs at 3945fps...

The key is always surrounds these three facts:
(1) They are using/testing at
least a standard-length barrel. That gives them 90-95fps over your 22" barrel at the start.
(2) They have developed these loads in a true pressure-test set-up where they can precisely bump up to the ceiling without going over it.
(3) Hornady in particular is supposedly using a proprietary powder type/composition not available to the general public as yet. One reason (might be that) the mixes are engineered as cartridge/bulletweight-specific)
+1 to Jim243 on bullet placement/precision a being the most critical factor within the range of normally-expected ballistics. I hit three coyotes when I was stationed in New Mexico back in `75-`77. One w/ a Swift/53gr doing 3,750 at the muzzle. The other with my M77V 243/87gr doing 3,200. All three were poleaxed and never new what hit them.
(The antelope didn't complain much with that 87gr'r either)
