Alek - welcome to the forum. Its good to have you here.

I never shot a .58 caliber Renegade with the 1:48 twist. I have talked to people that have and they said they are excellent shooters with both roundball and conical. I think a big conical out of that would stop about any critter you want to tackle.

I do own and shoot numerous .54 caliber Renegades. All of them are good shooters, the rifle is nice to handle. Recoil can get a little stiff with heavy loads, and if you have the extra money I would go with the Hawkins model just for the stock design in the big bore rifle. But the Renegade is a real meat and potatoes rifle that will shoot excellent time after time.

There are also a lot of drop in barrels you can purchase from Green Mountain Barrel company to make that rifle do about anything you want it to do, from a .32 caliber for squirrel hunting to a .62 caliber smoothbore for bird hunting...
