Greg - you’re starting the “Great Debate” on barrel twist and bullets...
Edited to correct to correct twist data:
Knight has a 1:28 twist in the .50, and a 1:26 in the .52 caliber. The .52 is being phased out IMHO - it’s never caught on as expected / hoped / etc. But - it’s a good rifle if you are willing to look for the solid bullets.
Reality - the 1:28 is going to do everything you need for Idaho - I was a resident for 51 years, and still hunt there every year that I can. You’ll be fine with a Knight, but you’ll have to put in the homework to get “your” load for the rifle.
The regular posters on here have way more knowledge about what to start with than I do - just ask, and take some notes on where to start.
Idaholewis had some stupid tight groups at what ranges most would say couldn’t be possible with an antique.
sabotloader has posted a number of Knight related information - read his posts and see what is possible with a little time and effort.
My “western” Knight is set up about identical to his - Williams peep and fiber optic front sight, Western ignition pack from Knight.
IMHO - the Knight is the easiest route to take for a NW legal rifle. Not to down play the CVA or TC - I’m just a Knight fan from cost and experience for my needs. And I have a TC Hawken fir the days that nostalgia strikes...
