Which chamber for 40XB

[Boydo]

Im looking for suggestions on what chamber to get for my 40XB build. This rifle will be used as a trainer, but my main concern is accuracy for my local steel silouhette shoots. I have read that certain chambers are tight and hard on certain types of ammo. I will most likely be shooting Eley black box or lapua center x but if i could chamber the bulk pack stuff and shoot decent with it that would be great. Any help is appreciated

I can't really say. But I did just send mine up to Hart rifle barrels this morning with the same question. I will be doing the same with mine. It will go into a McMillan remington sporter stock with a Leupold 6.5x20 EFR and hopefully it will make weight.
