Having hunted Elk,Deep, Antelope, in the Wyoming Rockies:
My 1st choice is, (my 1st rifle) 1968 Rem 700 BDL, totally stock, which included Rem's Blued, factory, SS BBL, freefloated by me using sandpaper & polyurethane to seal, with their amazing, "litigation proof" factory trigger set to 3.0 lbs, (and Harris bipod if course ) to work up max loads at the 1968 standard of 180/ 3080 FPS in a 24"Er. Using 72.5/4350-180 Nosler partition for Elk, and 180 BT FOR Deer & antilope . Somewhat shoulder pleasant when benching 100 rounds. 1/2". @100 yds was easy at near max loads, and consistent at colder, higher elevations. Almost as fast as a Weatherby, you could match it if you EXTENDed THE CHAMBERS throat .1 or .15", and let the brass grow longer necks to fit it.
Partition and BT Similar in ballistics: BUT the secret is to use max point blank range for an elks 8 or 10" zone. No holdover/ hold under worries at any range or angle. **you know you can't possibly judge it anyway, when you hear that tree crashing rumble tumbling down the mountain. Or when that herd of cows finally emerge running full tilt, from the deadfall/ thick forest nearby, or from the only clearing on sone distant clearcut, and you have seconds to guess where the bull has placed himself.
The 24" Rem is faster, lighter, easier to get to when on horseback or waking through deadfall, or when the quick shot is the only shot you get.
Bought 2 cases if Rem 180 factory core-locts, 1/2" Group @100 yds, Same poi year after year l@ 3" high at 100- I stopped reloading fir this. And only deer hunted, NYS, with these.
My 2nd choice -was converting Rems "338 Win Mag Classic" to a mountain rifle.
I asked K McMillan, to custom design and clone, Wearherbys MK V synthetic stock shape for the REM 338 WM classic, Bbl action. A stunner that even impressed Kelley. It turned heads whenever it appeared, and racks whenever it barked! So comfortable to benchrest. Light as a feather-quicker into action than the 300wm
**You could hear the sound of the trigger /sear mvmt, right up to the disconnection sound, and be able to Time let off! The sounds were conducted / amplified through the stock to your ear.
Yes, that same "Made by Swiss Watchmakers, Litigation Free" fully adjustable (target capable) trigger, set at 2.5 lbs.
SO what if THE 250/arched like a 3o-06? MPBR IS THE SIGHT IN RULE. That 250 gives you expanded options of when to fire!
