Ideas or thoughts on a .375 Sabotless SML build?

[luv2shoot]

Been thinking about a .375 SML sabotless build. I see some flat base .375 bullets in the .384 BC range.Attractive to say the least. Anyone have experience doing this caliber with the way I'm prposing?
1/12" twist  maybe?

I currently have two 10mlii's in 50 cal. Was thinking of :

# 1 converting one 10mlii by switching the barrel ( least expensive route) 
#2 buy a CVA Apex and convert
#3 build on a 700ml -209
# 4 or I'm plain nuts. More money than brains LOL....

I think I posted this in error on the wrong forum. Sorry.

You could use a Savage or Stevens or Remington actions they would be better than the CVA. I have a Stevens 45 McGowen with the 209 bolt head and shoot Barnes 290gr TEZ sabot less no sizing. why not just go with a .338 they have some good bullet.
