Help me build this rifle.

[Encore4me]

I am wanting to build a left hand 450 Bushmaster on a tikka action. I figure the best way would be to buy a Tikka and have the barrel changed.

What caliber should I start with?

Will any magazines fit a 450?

What bolt do I need?

I’m sure it can be done but I don’t really know where to start.

This sounds like a Ruger American easy button. There are a few lefty 450’s on GB now.

Any Tikka T3 with a .473 bolt face (308 Win, 22-250 Rem) should work as a doner rifle. Then send it to a competent gunsmith to screw on a 450B barrel and set up an AICS style magazine for an aftermarket stock available in left hand. This project sounds a lot like $3000! Lol

Buy a lefty Tikka 243 with an 8 twist barrel, get a Preferred Prefit for about $500, sell factory take off to me for $100. Have a gunsmith swap barrels or DIY.

I second Preferred Barrel prefits if they make the barrel. I've been happy with the few I now have.

There's a lot of info how to change barrels yourself, if you are into that sort of stuff. If you can find a gunsmith to pull the Tikka barrel and screw on the prefit, that would be nice.

I was thinking of posting this exact thing today, but a righty!

What contour did you end up getting? OEM stock? I'm wanting stock contour on a new barrel and wondering how close the lite contour matches up to the factory barrel contour

I went with the #3 and it’s bigger than factory sporter. I went with the Stocky VG and I had already opened it to Sendero. Sorry.

I’m curious of the intended use of the rifle. Why the 450?
Or is it just for fun?

Did you ever get this done ? I was wanting to do the same in 450 Marlin

I’m going to guess straight wall state for whitetail or just a 150yd hammer on them anywhere.

Which is the reason I’d build one.

Follow up for this thread, I end up finding a Ruger Hawkeye chambered for 450 BM. It is for a straight walled state whitetail hunting.
