Roper,
I am glad that you are happy with your A-bolt. As you like it so much, would you attempt to build a rifle that is capable of groups a third the size of your present 3/4 inch groups? Would you want to guarantee that accuracy on thay action?
Those are the choices that custom riflesmiths make. Any smith would probably agree to rebarrel any action so long as the chambering was safe in that action - there are a few that would even rebarrel and rechamber in a chambering that was not safe. Be that as it may how many would build a custom on the A-bolt action.
Well Paul, I'm not a gunsmith so I really cann't answer as to what I'd guarantee but I do have alittle knowledge in have things build and what to expect in groups. If I was to build a new 300RUM same caliber as the A-Bolt using the A-Bolt action I would get a McMillian stock choice of barrel be a Broughton 5c 1/11 twist or a Lilja 1/11 twist 26" long 4# contour. With a standard chamber I'd expect groups around 1/2" maybe alittle less for 3 shots.
As to who would guarantee in writng .250 groups with a 300RUM cal mag hunting rifle with a standard chamber, can happen I guess sure like to know that gunsmiths name. I've had rifle build by Speedy,
Hammond,K&P,Kelby,Chanlyn,Dowling,Bryant,Hart and Lee Six plus others and and they have always said
subject to the action checking out and the actions I've use Browning,Sako,Ruger77,Ruger#1,Win
Rem700,Rem40x,Hall,Panda,Kodiak,Mark X,Rem X-P and I've never had one rejected but some have
taken alittle work.
One thing I've learned is I don't comment on things I don't own or shoot so when I build something it's off a rifle that I've already shot. Had I not owned the A-Bolt I would go out and buy an A-Bolt just to build a rifle nor would I got out and buy a rem 700 just to build a rifle.
As to what a gunsmith will and won't work on thats his business. Since Buster51 didn't say what caliber etc kind of second guessing maybe he wanted a cal that would work. Guys got to have alittle common sense like with the A-Bolt I've got or any action. I'd build another 300RUM or 7RUM but would go to another action if I wanted a 30-378wby.. Your limited to certain calibers using the A-Bolt since it is a magazine fed rifle and working on them can get costly. I sure don't want to get into a contest with you over this A-Bolt.
