Loading heavy bullets for .308 with a 1-8 twist...

I have a model 700 sporting an 18'' .308 1-8 twist barrel by AAC. I also have a decent selection of 200+ grain 30-cals to play around with... 208 A-Max, 220SMK, 220gr Sierra Pro Hunter, Hornady 225gr HPBT, and a pile of blemished 240gr SMK. Powders on hand: 4895, 4064, 4166, BLC2, CFE223, TAC, & Varget.

Hodgdon lists data for the 208 A-Max utilizing several of the powders I have on hand so I do have a decent starting point to work from..... I'm just really looking forward to see how some of the other 220-240gr bullets are going to shoot.

So here I am wondering what direction some of you fellas might pursue given the components listed. My only real goal for now is to get a couple nice shooting 220+gr loads put together, and see what kind of velocities they're going to produce out of this 18'' barrel.... Thanks for your time & input!

The 1in8" was intended to stabilize heavy subsonic rounds...

The 1 in 8'' was intended to stabilize any 30-cal bullet. They wouldn't have cut them at 18'' if they were designed exclusively for subs. Robert Silvers from AAC designed these barrels & when you read over the threads from Silencer Talk & 300blktalk - it's clear he was just trying to produce a barrel that would handle any 30 caliber projectile well - subs or supers.

What exactly do you hope to achieve with ths setup?

I don't have any big goals penciled out yet surrounding this 'setup'. It's a rifle that may shoot heavy-for-caliber bullets well..... So I suppose I'm trying to achieve that.
