Hi guys, looking for some input from some guys who have put similar rifles together.
I just picked up a Montana 8400 in 300 WSM (Yonkers rifle, not threaded).
I do plan on shooting it as is, and if it shoots well, I MAY just have it cut to 20” and threaded for my DD enticer STi.
I am however more interested in rebarreling the rifle. Lilja can cut the factory contour (or one slightly heavier and likely flute it). I have so far looked into 6.5 saum (currently in the lead if anyone knows a good smith for a Montana with the Saum reamer), 6.5 or 7 SS (I had one guy mention the Sherman may not feed reliably in the blind mag), 7 WSM, a faster twisted 270 WSM (if the modern longer bullets like the 170 will fit in the mag, 6.8 western (if it will feet and the coal with the 170 will fit), 6.5 prc.
The internal mag box is right around 3.044.
Looking to see if anyone has any input on the above cartridges in both performance and ability to reliably feed from the blind mag.
This will be an 18.5-20” barrel threaded for a can and will almost exclusively be shot with a suppressor. This is going to be a multi state all game gun. Looking to keep 2000 fps at 600 yards and although I am well aware and understand that energy really does not matter, 1300+ ft pounds of energy at 600. The goal of this is a lightweight mountain rifle in a magnum caliber that I can hunt just about if not everything in North America with, regardless of caliber restriction. I’m sure there are some places that require above .264 for certain species, but I’m not talking about the outliers.
Also. Has anyone used the Warne picatinny bases? The split ones, not the full rail. I assume they are plenty reliable? The leupold full length pic rail currently on the rifle is not only really thick, but makes loading the mag rather difficult. Doesn’t seem to be a ton of options for these. I was hoping Hawkins had some direct mounts for these. I looked into the Talley rings, however I know there are some stories of these failing
