When doing a smokeless build on a Remington is it easier to use a centerfire action or one from a Remington ML or is it required that you use one or the other. Also, I currently have a Encore ML; is that an easier route to go? Just buy a barrel from SMI or convert a 45-70 barrel? I hear there can be issues with 45-70 barrels having too large of a diameter to shoot without knurling the bullets. Sorry for all the questions but wanting to know which direction everyone recommends going?
