I got the Mark X to the range yesterday, It gave a little over 1 Moa with 350 woodleighs and 84 gr of Rl 15.
The old 375 barrel contour was much heavier than the new # 5 taper Shilen. I am going to add some Devcon Steel
to the forearm. Have any of you tried full length bedding the barrel channel on these big bores? I can tape the barrel and free float it, or bed the chamber and float the barrel. I can full bed the barrel and sand to float it later if it does not shoot.

I built one of these for mike, with a AB barrel (cuz that's what HE wanted) and it's shot like a house on fire... just everything we shot in it shot well.

I like full length bedded big bores. Hadn't bothered with a floating one.

This post kinda belongs in gunsmithing too!

I floated mine in a good quality synthetic stock and it does fine.

I always start with a tight bedded barrel and it almost always works just fine with big bores and the stability helps I think....if not you can always scrape it to a free float, won't work the other way however, so do it....
