Thinking of reboring my old faithful 7 mag barrel (#3 Douglas). Does anyone rebore magnum barrels from 7 mag to 300 or 338? Anyone ever have this done? What say you?
don't waste another dime on that Douglas junk, take it off the rifle, close your eyes and toss it in the dumpster .... Then get a brand new high quality Bartlein 30 cal barrel in the proper twist for todays high bc bullets and it will still work for all other bullets, money very well spent , cartridge would be your choice but I'd go with the 300 Win Mag, ammo is piled high on shelves from many different mfgs in many different bullet weights & types, 338 Win Mag is hard to find unless you're a handloader and have the ability to form cases from other belted mag brass... or have, or know someone with a stockpile of brass, I make mine out of Peterson 7mm Rem Mag brass with cream of wheat, 12 gr of Blue Dot and a paraffin wax plug, one pop and you're done, necks end up a bit short but no trimming required for the life of the brass
Bugholes have 30 cal Bartlein barrels in stock, ready to ship in the #3 contour in 29" blanks, you can have your smith cut it to 28" or anywhere down to 20" .... They can also flute the barrel for ya, choose from many different fluting styles
I have two 29" 30 cal #3B blanks enroute from bugholes, one fluted and one round
reboring an old junk barrel is a waste of time & money for zero gain and you're still stuck with junk
