Seekins PH3 Barrel Changes

You running short action cartridges out of a long action zermatt origin? I was leaning towards a zermatt now liking the stock options, bolt head swaps etc. but was thinking i would need to go 300 wsm with my short action 6.5 creed etc. didnt even think about running a long action for everything. 300 win ammo is quite a bit cheaper than 300 wsm.

The short action magnums really do better in a medium action. I am not running a short action cartridge in a long action. I have multiple short action origins and only one long action. My next will be a medium but there are less options for all accessories.
 
Checking in to keep up with this one.
I have a ph3 in 6cm that I will be looking for a second barrel for soon.
My initial idea was for a 308, but if a wsm will fit, that would be amazing.

I bought a 6.5CM and a .308 barrel from an aftermarket supplier and I couldn’t be happier! Now I have a .25CM barrel on order. Oh yeah, POI shift was about 3” high and right, 6.5 to .308, which I feel is reasonable. I am considering ordering a 7mm-08 as well. All of these calibers use the same size bolt head but magazines can be temperamental.
 
Just saw this on a google search since I’m leaning on getting a ph3 in 7PRC and then getting a barrel for 6.5PRC. Seems to be the solution to the long action to short action. There is a specific option for a long action to short action cartridge magazine.

Please keep me posted if you go this route. This looks like the ticket
 
The Apex Predator mags work great, and definitely open up a lot of options for the long action models. I've done a few barrels in 300wsm for guys in short actions, and they've all been happy so far! For my NRL gun I have 6.5cm, 25cm, 6cm, 22cm, and 25PRC barrels that I swap around often depending on what kind of mood I'm in. For the HIT I have 6 Dasher, 22ARC, 6cm, 6.5prc, and 25x47.
