I'm thinking about a Weatherby Mk. action with a 28" heavy barrel chambered for the .300 RUM. Has anyone put a custom rifle together with a Weatherby action? The Weatherby action seems to be machined with more care than anything I've seen from Remington or Winchester, my goal is a 150 gr. Failsafe at around 3700 fps that will consistantly hold 5" @ 500 yards.

What's it going to cost you? Nesika sells actions for 850-1100 dollars. I found that by the time I paid to have a Remington reciever trued that I had close to the same money, so why not go with the best on the market?
I am not trying to push my brand on you, I just think that any of the premium actions are within range if you start customizing the common production guns. Stohle, Whichita, Nesika Bay, Sinclair all make actions about the same price range as quoted above.
The one exception is if you are the gunsmith,then your labor cost are free.

I came to this conclusion after realizing that I paid less for my Nesika 300WSM than I did for my Remington 220 Swift.

Good luck

Chuck's right. There are plenty of good actions out there (he missed Borden (nesika) and Mcmillan). The Weatherby action is needlessly heavy for most applications as the receiver is a one size fits all affair from the 460 down with only a change in the bolt stop grove, bolt face and bottom metal. Unless you already have a Weatherby try one from Chucks list.

Thanks for the info. This will be used as a long range hunting rifle, are there any stocks out there for those type of actions that are designed more like a traditional hunting stock?

Oldfart, I've see, in person, a couple of full-house custom jobs built by the David Miller Company that were based on Weatherby Mark V actions. Beautiful work, but very expensive! Those actions were completely reworked.

I think the Mark V action (a great action in most repsects) would be great if you wanted a custom .30-378 (one of my hunting partners has one), but if you want a custom .300 RUM, I'd keep things simple and base it on a Model 700 action that was originally built as a .300 RUM.

That way, action work requirements will be minimal, etc.

McMillan make a stock for that application. Just get ready to wait four months to get it though. But is a good stock to wait for. You just have to make sure the Bolt throw in the stock is relieved for the bolt to drop properly (from experience). Nesika make a hunter version of their actions that is very light but ridged.
I am in the process of makeing two of them now.

I have two custom 300ultra mags and went with stainless 700 actions.They are lighter and it is quite easy to lap the lugs unlike the weatherby action.There are also far more stocks available for the 700 action as well as triggers and other accessories.

I hope this helps you I have a few guns that have been built for me by Mark Brown and I only have the best things to say about him and them if you are serious check out the web site and call him.

Just looked on McMillans site and they can inlet several different stocks for Nesika. Also Nesika can make their hunter version so it will fit into a Remington stock. This info came off of their web sites.

Check out Borden's site. They have a well designed stock that I've used on two Weatherby's a 358 STA and a 378. Try http://www.rimrockstocks.com/.
