Thanks, great write-up. I didn't know the Prairie Hunter was on an axis action and after checking it out, Savage Precision Rifles appear to be axis receivers, also. I wonder if the Prairie Hunter and Precisions are trued or get any extra attention compared to the Axis rifle? It looks like the Prairie Hunter and precision rifles have different bottom metal and the better metal magazines.ARP Savage Barrel Rifle | 6.8 SPC Forums (68forums.com)
Here is a write up I did of my bolt action 6.8 based off of a .224V donor rifle. Some pictures and discussion about the Axis design and mag block are there. Although this was originally a prairie hunter, most things should remain the same as your .243 Axis as the Prairie Hunter is actually an Axis receiver, which I did not know until receiving it.
If you can get ahold of Savage Parts Department and order a mag for the Prairie Hunter .224V, it should be a direct fit with reliable loading.
I didn't see any .224V mags on Savage's website. I will call to see if they have any available if not, I will use the .243 I have or order .223 (they have the spacer block). I hope this doesn't interfere with the PTG bolt head?
I was going to order the bolt head today but got sidetracked and ran out of time comparing the five different savage bolt heads I have. It looks like the Axis bolt is not quite the same. The buffers (the spacer behind the bolt heads) are slightly different. I don't have another axis bolt head to compare it to though. PTG, I believe, makes their bolt heads at different lengths depending on what cartridge and magazine is being used. I'll need to call them to ensure I order the correct bolt head.
