300 weatherby vs 300 remington ultra mag

Any thoughts on comparing a 300 weatherby accumark vs a 300 remington ultra mag sendero. Will the weatherby be less accurate than the RUM because of the freebore?

Re: 300 weatherby vs 300 remington ultra mag

I have always believe that. A good friend of mine has worked at Douglas Barrels here in WV for 25 years and he told me that yes the freebore Weatherby's have less accuracy.

My practical experiences with the Weatherby rifles lead me to believe that also. I've never been satisfied with the accuracy of any I've had a chance to fire or see someone else fire!

But does the Accumark have the free bore? I was also under the impression that not all Weatherby's have freebore. But that might only be non (Weatherby) magnum.

Between the two I'd go for the Remington for sure! I like the 300rum better also!

My Weatherby Accumark in 300 Win Mag has quite a bit of freebore compared to other 300 Win Mags that I've owned but after removing the spacer in the mag box I was able to seat the bullets out farther thus increasing powder capacity. I've shot 180 Nosler BallisticTips at 3100fps with MOA accuracy to 400yds. I believe all Weatherby chamberings have the long freebore unless reamed with a custom reamer. After saying all of this I would pick the Sendero 300 RUM over the 300 Weatherby Accumark because in the end I think you can end up with a more consistantly accurate rifle with the Remington over the Weatherby. Plus as the previous poster replied "I like the 300 RUM better also"

I would seriously concider the Sendero and use the money you saved for a great scope. I just swapped my .300 Weatherby for a Bushmaster, my .300 ultra is more accurate than the Weatherby was. Weatherby didn't like boattails. It's my understanding that all Weatherby cartridges have the freebore, standard calibers don't.

Re: 300 weatherby vs 300 remington ultra mag

I've heard that Remington is now "incorporating" the use of "factory throat erosion" in their rifles too. It allows the lawyers to be happier, and a cartrige to use hotter loadings safer. Although detrimental to accuracy. Although if I had to do it over again, I would go for the Remington also. NO belt, thats a big one, and Remington parts are extremely easy to find. OH yes, and the money you save you can invest in a scope! Think somebody already said that, smart! [img]images/icons/wink.gif[/img]

Personally, I don't like Weatherby rifles much, never will own one. I don't mind a belted case if pressures are kept down, but always prefer a nonbelted, the Ultra for example would get my vote.

I talked to John Hoover today, he said he was getting 3500 fps out of his 32" barreled 300 Ultra with a 210 JLK with brass lasting 3-4 firings. He said it does a number on the deer meat though.

Freebore might be a source of inaccuracy but, I think it may have more to do with people bumping the shoulder back too far on the belted cases that leads to problems with alignment to the bore.

I think you're better off with a Winchester or Remington in the long run, Armalite make a damn nice rifle too. Aftermarket goodies for a Ruger are still better than a Weatherby and they make a good rifle, just not as much out there for them like there is for the remchesters...

Re: 300 weatherby vs 300 remington ultra mag

Well, I like my 300WBY, but it is a custom job so I was able to control for alot. It shoots .35 groups at 100yds consistantly. I don't like the Remington - because then you are stuck with remington brass, which I have not found to be good. I do like the 300UM, but I just would like to have better componants available - I know you can get federal ammo - but I reload. Weatherby/Norma brass is way better. The headspace issue with the belted mags is not an issue anymore if you reload - so don't be food by that old mantra.
I have had several problems with remington ammunition and componants, so I am not very objective on this one. Remington has also been less than helpful when I have went to them with concerns about their products. I also love the 300WBY. You can get a little more speed out of the 300UM, but in reality not that much. But you can go either way - you wont be disapointed.
