Hello DM,With RB, you'd be fine with ~20gr. Them intermediate rate of twist barrels really open your groups with heavier charges, IMHO. Increase your load gradual like, till your groups start to open up then back off a scoach.
I used to have one of those Frontiers in .50. It was part of a consignment for Cabelas that features the DeLuxe curly maple stock without all the brass. I liked it so good that I kept the stock, ferrules, and trigger. Replaced the barrel with a .45 Rice and the lock with a L&R Ketland.
From my experience with the Frontier, I might advise you to order spare ferrule screws. DO IT RITE MEOW! That's how the barrel is mounted, and Elisa over at Pedersoli will make sure you don't get 'em afore the seasons change.
When you say increments, do you mean 5 grains at a time?
I've seen pictures of the deluxe curly maple, and would like to find one like that.
Question, what is Ferrell screws? I'm new to the Pedersoli like this.
