So I have a new pta I bought for $500 and deciding what iam going to do with it. Thinking I want to build a 300wm to shoot heavy bullets. Anyone have any experience on building one on a short action and how long of coal is possible?

Loading won't be the problem, will the PTA eject a 300 WM case? If you ever have to eject a loaded round, you'll need to remove the bolt
is that because of the smaller ports on the pta?
No... it's because of the shorter bolt travel.
So did you build one? No someone who had one? What was your opinion of it? If you built one any pointers.
The bolt head for a magnum short action has been like finding hens teeth in the past. You may find a savage unit, you may have to buy one from PT&G or you could make one from a long action bolt head by trimming the nose. If you make one out of a long action you might as well remove the radius so you can move the spring washers location. The original short action piece is a little longer which will effect your firing pin protrusion. From there you will need to consider your approach to reducing the spring tension/preload after you get the protrusion set and still maintain the cocking distance. It is single shot so there is not much else to consider. Thread size is 1-1/8-20. (1.120-20)
The platform is good to go, and it will shoot fine with a good barrel and a good shooter. Many people have built long range rifles from a PTA.
