Hello
For you gunsmiths or guys who have possibly done this.. What does it take? I'm thinking of buying a rifle I like a lot in 270win and converting it to 270wby. Ive always wanted a 270wby and I dont like any of their offerings currently. Please let me know what I'm getting in to and what I need to consider. And yes if its a stupid idea you can tell me that as well. Thank you
 
Ok i will look into those but Ive always wanted a 270wby

Okay I've read that you want a .270 Weatherby, I get it. I always wanted a wildcat cartridge, so I settled on the .270 Ackley Improved. The performance will match or supersede the .270 Weatherby at about 1/2 the cost for ammunition, or for brass if I want to go that way. Unless you purchase a donor rifle that is .270 Winchester there are not too many options for you. The .270 Winchester Short Magnum is a viable choice, there's around 100 feet per second difference between the two cartridges; but.....it's not a .270 Weatherby. You next option would be to purchase a .270 Winchester rifle that you really like, have the bolt opened and the rifle rechambered, and.....probably the feed rails will have to be reworked. This is not going to be a cheap date, and.....in all likelihood you will be working with a factory barrel and probably that barrel length will be from 22-24 inches, and not a 26 inch barrel where the overbore cartridges really shine and maximize performance. For me if I really wanted to have a fancy rifle that "had" to be in .270 Weatherby I would find a donor rifle with a magnum action (bolt face), find a good gunsmith and have that gunsmith blueprint the action, install a quality barrel (26 inch) reblue the action/barrel, do a trigger job, glass bed and pillar bed the action ($600-800) and purchase a fancy stock of your choosing. My son wants a .300 WinMag, so for Christmas he will be getting a .300 WinMag. We like Ruger 77 tang safety actions, I found a donor rifle in 7mm RemMag on GunBroker for $350, installing a 26 inch (1-10) Lilja barrel, blueprinting the action, rebluing the action, and doing a trigger job. I am doing the stock work myself, glass/pillar bedding and a recoil pad. I'll refinish the stock, my son will not know it but he will be spraying the stock with two to three very light (mist) coats of flat automotive clear when it's done; we like the Ruger stocks. Good luck with what you decide on doing.
 
I have taken both of my .270 win Tikka t3's and re-chambered them to 270 wby mag. and opened up the bolt face to .532". They shoot Spectacular with 130 ttsx at 3350fps with RL23. Sub 1/2"moa @ 100yds and point blank out to 400yds with a 200 yard zero. What is not to like? By using a tikka 270 donor you don't need a new trigger or altered stock. Lite,strong inexpensive and very accurate!

Alibiiv, thank you. Lots of things to consider. I am planning on buying a 270 win donor rifle so the 270wby could work. The barrel length issue you mentioned could be a sticking point. I believe the length on this rifle is 24 which might work but ill need to look into this.

As mentioned I could do a 270wsm but Ive shot my buddies and wasnt overly impressed. I could do the 27 Nosler but I think if i do that Ill buy a rifle chambered in it to start or build one.
 
I wouldn't buy a 270 donor to make it something that requires more smith work. Buy something with the mag bolt face and then that's money and time you don't have to give the smith.

If you already have the 270 then ignore that comment and proceed with your plan
If your donor rifle is a 270 Win you can open up the bolt face and re-chamber the barrel to 270 Wby.

This is what i was hoping to hear. My plan was to take a new Sako S20 rifle. Which is pretty close to a tikka.
