It’s not that difficult. The major difference between a bolt gun and a gas gun is the over all length aka (OAL). The gas gun OAL is constrained to fit the magazine unless single loading. The bolt gun allows longer OAL if properly set up. As for barrel rate of twist 1-8” is what I employ on my bolt gun for the Sierra 77gr HPBT, 75gr A-Max (Hornady), and Sierra 80gr HPBT. As for powder I prefer RX15. Even if you have not loaded centerfire rifle there’s nothing magic here. A good manual we’ll walk you thru the steps. One may obtain a cartridge case gauge to check the case for proper dimensional fit.

My bolt guns are no longer state of the art but then neither am I. On a good day I can live up to the accuracy potential of the gun and the gun shoots right with the latest/greatest platforms being used today.

Oh yes the bolt gun on the bottom is .223.
