Just got 2 mtn tac LA 3rd mags for my LA Tikka in 300wsm. No feeding issues. I didn't have any feeding issues on new 300wsm brass in factory mags but after 1x firing they dragged on the insides so I switched.
Great. Those go right into a stock t3 without any bottom metal modification and hold 3 wsm rounds?
Yep. Mine click in a bit firmer than factory but the front pops out on probably half inch when the mag release is hit. It holds 3 wsm rounds and I can click mine in on a closed bolt. Factory bottom "metal" in a rough tech stock
I don’t know what to call it, Bottom plastic? This is off topic a little but I don’t have my 300wsm barrel yet. Plan to use a factory one for now soon as I find a new take off. With the factory 300 wsm how much freebore do they have? I’m reading it’s more than saami which is what I have found in my other tikkas. What would the coal be in with a 200 or 205 loaded near the lands? Thanks
Not sure. Mine is a long throated wsm from PVA. I shoot 180ABs about 3 OAL to lands.
I’ll have to measure my Berger 205 EHs but they were longer than factory mag would handle.
That’s helpful. I’ve had my 270 wsm since 07. I’m bored of the projectile selection so I plan to get a factory 300 barrel, cut it down to 20 or 22” and add a brake. If I like the setup I’ll get a pac-nor barrel made. Just trying to figure out the details now
Sweet! What length did you go with and yhow much velocity did you loose? I have two tikkas. It’s been hard to decide what cartridge to go with but I’m getting hooked on the 300 wsm. Seems super efficient. Way off topic now
I cut to just under 22" and lost somewhere around 30 fps, cutting down from the 24.3", as indicated using 205 Elite Hunters and 6.5 Staball. I am getting 3120 fps with 175 LRX using Staball 6.5 and 2867 fps with Berger 205 Elite Hunters using Staball 6.5... but the 205 Elite Hunter load is pretty hot. Still haven't had time to measure COAL but definitely need the HCA magazine for the 205 EH load.Sweet! What length did you go with and yhow much velocity did you loose? I have two tikkas.

more specifically, the feed lips on the WSM mag are longer than the long action mags... therefore, WSM rounds would not be contained by a long action magazine to the extent necessary for reliable feeding.
