Home Forums Hunting & Shooting Hunting Rifles Building a 6mm/223 aka 6x45mm on the cheap

I agree with you. I would want this rifle to be a repeater too.

No problems, but there isn't any surplus room with the heavier bullets. 80-85 gr is the heaviest I'll shot with the 6x45 any heavier velocity drops.

I also have a 6x47 on a Remington action, it has more magazine length but is twisted 1-12 so longer 6mm bullets don't shot as well.
It's the one on the left, it has a 20"custom barrel that's been rebored and rechambered with a gain twist by Ron Smith a southern Alberta gunsmith.

How about just a boring Off the shelf 6.5 grendel

I always liked the looks of the Remington 600 and 660's.

I have considered it and won't rule it out, yet. I also have thoughts of getting a worn out sporter 22-250 and making it into a 250 Savage. I will have to wait and see what deal materializes for me.

I have a 6-250 that’s SWEET. Might keep that in mind as an option too.

there's a couple new savage actions for sale for $280 on another site already with the 223 bolt head.

grab that, a prefit barrel for $300 and a nice stock and $700-800 is within reach.

Is that a straight neck down from the 250 Savage or neck up from the 22-250? I remember years ago reading about the 6mm International, not that one is it?

Which site?

How bad do you want one, as I could probably be talked out of this rifle.

Sorry for some of the crappy pictures but they're all I have on my computer. Definitely not my cheapest Savage build, but they usually cost you more than you think you're going to spend. I'm just going a different direction since I got my suppressors and this barrel is too long and I don't want to cut it down to thread. Probably wouldn't be as cheap as the one you want to build, but I'm also fairly motivated.

Thanks.

Nice rifle. I would not be close to what you have in it. If I go with a Savage, I am hoping to find one of the old 110's with the staggered feed magazine, fully adjustable trigger, and monte carlo hardwood stock. Years ago I had one in 7mm 08 Remington and I killed a bunch of deer with it.

I never thought I'd get close to what I have in it when I offered it. You never do when you put money into a Savage and a no-name gunsmith. However, I've kind of lost interest in this rifle and would like to move on to something different. I can understand though where you're going.

Sweet trio of vixens! I like the 600s too!

How good 77gr tmk are on game, it’s be hard pressed to not build a 6x45 based around a 95gr tmk.



Then again about 27.5 grains of 4198 and 108 eld-ms at 2600 from a 21” barrel will result in fist sized groups at 500 and hold single digit sd in mass produce load powder measure dropped.


9 twist 250$ ruger Americans will stabilize 28 grains of 4198 and 105’s at sea level and 30 degree temps.

I built a 6X45 AR with a Black Hole Weaponry barrel a few years ago. With the now-discontinued Sierra 80 grain Single Shot Pistol bullets (I lucked into 500 of them), I am getting right around 2700 fps and superb accuracy (20" barrel). It has accounted for three whitetails and a few coyotes.

I picked up a Remington .223 for basically nothing a while back and considered doing exactly what you are are planning, OP, but I decided on building a 7TCU instead. I made that decision so that I could shoot the excellent Nosler 120 grain BTs. With a 20" barrel, I should be able to get close to 2600 fps. I did have to modify the mag box to fit the longer cartridge and I may have to do a bit of feel lip modification due to the "blown-out" body taper on the TCU, but I think it will be worth it. I am getting a Wilson barrel (#4) for it. Cut to length, chambered, fluted and threaded it was less than $500 from Ragged Hole Barrels. Considering I only paid $90 for the donor, even with a great stock, I am going to be into it for less than $1000 when all is said and done.

Oh, another tip on gauges, you can rent them from remearrentals.com for $7, plus shipping. https://www.reamerrentals.com/ProductDetails.asp?ProductCode=6x45%2Eg

I just saw the question about why I used the Howa for my build, well simple answer is i had one. It has been a good rifle, accurate and easy to load for although a little heavy. I love my 6PPC's so originally the plan was to buy a Howa mini in 6.5 Grendel, due to the bolt face, and than rebarrel that to a 6PPC. Well what happened was that since I do a lot of deer hunting, and use three other 6.5's of various types, I thought I would at least play with the Grendel before re-barreling. What I found however was a neat little rifle, that has been very accurate right out of the box with factory loads and way less than 1 MOA with some thrown together loads. So that's where the Howa in 6x45 came in, take a rilfe and caliber I rarely use and just change the barrel with a prefit to a more usable cartridge 6mm cartridge without any bolt face mods. Also I have a grandson coming up and think this might be a great starter rifle.

Thanks for the tip on the gauges. The 7mm TCU sounds like a fun project. Please post your results when you get it done.

I totally understand. Some of my interest in a small cartridge is my son is 4 and I hope he wants to shoot and hunt like me. I could had have something mild and fun for him to shoot when he gets older.
