Converting .223 to 6.5x47 Lapua

[Yoshi]

Howdy! I have a Savage .223 that I want to convert to 6.5x47 Lapua. Possible? If so, other than a new barrel, what else do I need to change? Can I get by with just changing the bolt-head or do I need a new bolt?

Thanks,
Yoshi

New barrel, new bolt head, new extractor, new magazine and follower should get you what you're looking for.

You could however have your chamber cut for 223 ackley improved without changing a thing.

In all honesty, why not go with 6X45? Same bolt, just a new barrel. Reloading is simple with a run thru the sizing die. With a bolt you can go anywhere from 55gr to over a 100gr.

Probably a new front baffle too.

While the cartridges are about the same length, the new magazine will hold the Lapua case head a little further back.

Thanks all! The reason I want to shoot 6.5x47L is for Precision Rifle Series (PRS) matches which go to +1000yds. I generally shoot a .260 but finding H4350 is getting hard. So, I hear the 6.5x47 is great with Varget and that's easy to get. There are some other reasons too, but component availability pushed me towards this selection.

I don't know anything about the 223AI or 6x45... Guessing the AI will peter out way before the 1000yds? 6x45?

Compared to a 260 yes a 223 ai or 6x45 will run out of gas at 1000.

6x45 is a 223 rem necked up to 6mm. I think its a dumb idea overall.

223 A/I is a rem case with no body taper and a 40 degree shoulder. The result is a small gain in velocity, roughly 100 fps with heavy bullets. Depending on your elevation and barrel length, the A/I can stay supersonic to 1K with an 80 grain bullet.

Either of these cartridges can be easily converted from a 223 rifle.

Not sure where you live where Varget is so widely available. Wherever that is, I want to move there!

Thanks Bill! The AI seems like a neat little round. How does it run in a semi?

I just looked at Grafs, Midsouth, and Natchez and they all have Varget. Yeah, most are the 1lb'ers with some 8s, but I never have trouble getting it... Unlike H4350. Always sold out.

Who orders 1#s online? Lol

Hey Bill, I'm gonna address 6x45.
1. 6x45 is a great caliber for AR's & bolts in states that require .243caliber for deer. 55gr up to 95gr in an AR, and over 100gr in a bolt. Def not a 1000yd round. But a round that is gaining in popularity due to extremely cheap brass and bullets.
2. Its a barrel swap and go.

The 4350 lack is odd, we do have a lot of IMR4350, close to the same? We have 8 lb containers of it up here, one of the first powders to come back in bulk.

Mine likes H4831sc. Have you tried it?

My 260 Rem LOVES RL-17.... 24" barrel, 2875 FPS, 1/2 MOA.

Ditto. I stocked up on this a long time ago and I don't need any other powder for .260. What sucks is I ran out of Federal match primers and haven't been able to get everything back to perfect again since.

I got the best results out of R17 in the 308 last week, need to explore it more.
