I built one way years ago on a 98 Mauser action with all the, then available, add on/conversion bells and whistles, trigger, bolt shroud, safety, etc. Used a Mcgowan barrel and stocked it in Mesquite. The darn thing shot better than any other rifle I had ever had at that time.
I wish I could remember the loads we worked up but ya had to hunt for bullets. This was back in the late 60's early 70's. Killed several deer with it and shot a bunch of paper just screwing around. Intended to take it on an antelope hunt but that fell apart. Never got to shoot it past 200 but knew it would work. Sold it to a guy who was slobbering over the gun.....
I thought it was cool to have an 06, a 25-06 and then wanted to build a 35 Whelen (no one even talked about a 6mm-06 back then)..... so much for that with school, work and girl friend.
I guess the 25 is a bit of a niche caliber but there does seem to be some rejuvenation going on....
I would love to have a Ruger #1B in that caliber today.....Just me
