If you want a repeater and you are willing to spend in the 1200 dollar range you cannot go wrong with a Freedom Arms. I haven’t done much long range shooting but the 3 FA’s I own all shoot 1” or less at 50 yards, a 454 Casull, 475 Linebaugh, and a model 97 22lr. I manage to ring a 12” 250 yard steel gong at our range with fair regularity as well. FA is also the choice of silhouette shooters. If I wanted one for all out long range shooting I would go with the 10” 44 magnum. My two 83s have 6” barrels and the 97 has a 5.5” barrel.
No other revolver or semi-auto I have fooled with compares to what you get with a FA. They are worth the money.
Be Safe,
Scott
