I'm looking into doing this wildcat. I will be doing it on a rem 700 SA. I have 2 300 WSMs and enjoy them both. This seems to be the natural progression. Has anybody done this? Any bright ideas? Flame away!

Go for it. My 350 wsm was a great conversion project - very successful. It's a good performer. A 366 version would be as good. Get the right twist for 286gr and heavier. The Win70 is a good platform having a longer mag.
 
I just had one built on a Sako 85. Just waiting for it to arrive. The gunsmith did the barrel break in and was getting about 150-200 Fps faster then my 9.3x62

i think Charlie Sisks and John Barsness has done the 9.3BS based on the 350 remington case.

I guess that sounds about right, what weight of projectile are you using? It seems like it should be moving faster considering comparing the case capacities (thinking in my head 30-06 vs. 300WSM), but I guess your bullet weight is fairly heavy, are you loading it very hot?

Good for you for doing something this different, I have admiration for folks that can think up and make hybrids like this.

Using Nosler 250 gr Accubond, using Reloader 17 and ACC 4350 with Norma brass. The gunsmith didn't push it to hard yet. It will be 3-4 weeks before I get, I had it built in the US. I will try to go 2-5 grs above what's been used so far, gots the Reloader 17 data off Nosler forums and haven't reach the max load yet. The gunsmith also used a 285gr Lapua with good results.
 
Well BUM considering that this would be a significant step up from the original 366 Wagner, and considering the fact that Marg shoots a 308 in a 77 RSI, I'm not really seeing the connection here.............I agree Ted OWNS the 366 Wagner, but I think we'll have to cut this one loose from the association with the Wagners, sorry, but he can't own the caliber, just the cartridge..............

Sounds good and a great option for a bigger bore on the WSM platform. It would be great if the cases could be stamped 366 WSM.

Are you using the 325 WSM case for this rig...?

Winchester goofed bigtime when they brought out the .325 WSM instead of the .375 version. A .366 would fill
the bill nicely for anything from plinking to the big stuff.:)
The 375Ruger would have preempted a 375WSM so either one would be a bigtime goof. Same with a 366WSM. Sounds good for a bunch of gunnuts sitting around, but Mr. Regular Joe Public would not be buying any of them.

I notice a lot of used 300 & 270WSMs FS these days, so it seems that even they has lost a bit of it's market thrust.
