Factory ammo is stupid money. Hornady xtp is the best hunting bullet. If your plinking, a campro plated, or equivalent. Magnum pistol powder like 2400, or H110. Fireballs at dusk. Perfect boondocking protection rifle, or 《75yds hunting.
Doubt you will have much luck finding 44 special. It's irrelevant, and sometimes, the feeding is a problem. Certainly don't need to worry about recoil, using low power loads in a rifle.
