gman-I'll add a couple of comments. I've had the pleasure to own and run a G33/40 for 2 decades now. And though I have a find piece of Tessier for it I've always run it with a Brown stock as for me it's a pure plain hunting machine tool. Plus to be honest I've never had the interest in sinking the kind of cheddar into the wood handle that it would take to get it nice.
I'm of the opinion that if I'm gonna run a wood gun that's it's gonna be nice (by my way of thinking)..something like my 7 Mashburn Super here
I've been around the various Montana's quite a bit including the 280 AI. 4 me the 84L action just doesn't do anything for me. Does it work, it sure does but it just doesn't feel right to me.
I own a Montana in .308 and it's nice but once again the diff between how a Montana runs and how a fine Mauser runs is night and day. To me it's kind of like ones a quarter pounder with cheese and the others filet. Both will fill me up but there is a diff.
For the money the Kimber is a lot of gun, plus it's readily available and people don't have to wait for it. Nor do they need to stretch their imagination and or pocket book to get one. It's nice but to me it's a cookie cutter rig. But it will do the hunt job just fine It's a darn adequate rifle is what I'm trying to say.
I wouldn't turn a fine action like the G33 into an AI and I love AI rounds. I've known it done though so if that's the way you choose then Powder River Let er Buck and get after it.
Sounds like you're leaning to the Kimber and it'll do you just fine.
But, if you wish to go the way of the G33 you could always stick a fine piece of African Walnut on it for now (fiberglass) and then find a good stick later on. Chic Worthing would do a mighty fine job for you. I came darn close to sending him mine.
Best of luck to you in your decision and have a super 13!
