Who has one or has had one custom built? It seems to me Weatherby should have adopted this instead of the 6.5rpm and the 6.5x300, does anyone have any connection to Weatherby to ask this question? I recently bought a personal rifle off of Tim McWhorter it’s chambered in what he’s always deemed the 6.5wby, the numbers look great with all bullet weights and powders I’ve tried and it’s insanely accurate! Really would have gave the 6.5prc a time getting out the gate IMO, the 156s need a slightly longer mag anyways especially to get respective velocity so I see no argument of the short action theory if your goin to be versatile with what you can load.

I have one(6.5x257) factory mark v with pac nor barrel. Will be going up for sale soon. Fills a niche that's redundant with other rifles that I carry and shoot more.

I had one. I used 130 Shock Hammers @ 3,190 feet per second from 24" barrel. It is bored to 8mm.

I shot one off and on for a few years. It was bad, bad medicine for coyotes and antelope in open country.

The only issue with shooting any of the Wby's is limited availability of components and factory ammo.

The world is moving away from our beloved belted magnums, seems most of the younger writers and gunsmiths have decided that with all the new, bigger or equal sized non belted magnum cases the belted magnums are just, "too last century".

Currently I shoot the 6.5LRM and have fallen in love with it and will probably do an improved version for my next 6.5.

I have one built on a McMillan action. The only bullet that has ever been down the tube is a 140 Berger VLD. The initial load was 3,278 fps, but I'm at about 3250 now. I've had the barrel set back and rechambered once. The rifle is very accurate and it is vicious on deer. I developed (or tried) a load for a friend's factory 6.5x300 Wby and found it to be very finicky. I couldn't get it to shoot better than about .8-1", and when I could get it there it was less than 100 fps faster than my 6.5x257. Now it would shoot the Berger 140 3,550 fps plus, but it would be all over the place. I've heard of many 6.5x300's not shooting well and I've heard of several custom builders that won't chamber for it. Seems like some of the factory rifles that were shooting well were shooting the lighter bullets.

Maybe they needed faster twist rates to properly stabilize the chosen bullet?

My first .260 was Custom built AR. 1:9 was what all of them were being built on at the time and I was encouraged to go with a 1:8.5 if I intended to shoot 140gr pills.

If I built another 6.5, or I should say when, it will be a 1:8 so I can shoot heavier mono's, maybe even 1:7.5.

100-120gr spire point type bullets is what the 6.5's were chambered and barreled for, for most of a century.
