Re: Now the big decision What Caliber ?
I have a Manners MCS-T4a. They don't make stocks much heavier than that. I like it. But, you mentioned wanting to keep weight down. So, just fyi.
One option would be to get a 7mm barrel with an 8.5" twist for the soon to be released Berger 195gr bullet. You could order the barrel now and wait for the bullets to arrive. Then, possibly send a dummy round to PTG. It might be worth them making a special reamer to seat it out long for whatever cartridge you pick.
I wouldn't recommend that route for a one gun owner. But, it seems like you have most of the other bases covered.
There's a good thread around here somewhere discussing the potential of that bullet with various cartridges.
