I have two rifles that shoot really well, but are extremely heavy due to the barrels. One is a FN 7 Mag with a 26" #5; the other a factory 300 RUM Sendero (the original Senderos, not the newer ones). Any recommendations? I was thinking of taking them both to a #3 (or close the factory Remington mag contour) "Evil is powerless if the good are unafraid" -- Ronald Reagan "Ignorance of The People gives strength to totalitarians."

At the bottom left of this picture is the mailing, (PO BOX) shipping (street address) & telephione number of Dennis E Olsen of Plains MT.  He has very reasonable prices & his turn around is FAST. He turned a military 98K barrel per that drawing & it came out like this  and shoots like this.  Give him a call.

Not really "HOT" just loaded to "adult" levels, estimated 60,000 psi from "Quickload" data & actual chronographed Mv. Also, the Mauser in question is built on a Yugoslavian VZ500 action circa 1960s. (commercial version of the M48 Yugo) Kinda bass ackwards in this case. A military barrel on a commercial action.

Be aware that turning down button rifled barrels can have strange results. If button rifle barrels are not turned to their ultimate profile before rifling, then turning down the blank relieves pressure on the bore and the smaller the outside diameter, the larger the bore diameter. I once had an Obermeyer target barrel which was enlarged at the muzzle and at the breech and tapered in between. The bore, when air gauged, turned out to be right on specifications at the breech andmuzzle, but oversize in between. | |||

Not sure what type of barrel is on here. I think maybe a Pacnor or Shilen. "Evil is powerless if the good are unafraid" -- Ronald Reagan "Ignorance of The People gives strength to totalitarians."

Button rifled barrels can NOT be preturned, they have to be a uniform diameter the whole length. I have been turning barrels for about 50 years and have had minimal problems with button rifled barrels. Bill | |||

This is one situation where chryo treatment pays off. A good cryogenic treatment will relieve any imparted stress BEFORE the barrel is re-contoured. GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

Funny story about cryogenic treatment. I did a technical paper on it while in college - in 1986 - even talked to the guy that invented originally as a source. It was just catching on in the 80's, mainly with machine tools. "Evil is powerless if the good are unafraid" -- Ronald Reagan "Ignorance of The People gives strength to totalitarians."
