 Best weight bullet for 1 in 12 twist

Looking for the most accurate bullet weight for a 1 in 12 twist barrel. I'm figuring since alot of retro builds might have this twist rate, the folks here might have more knowledge than what I've been able to find. Specifically, looking to tweak as much as I can out of a Ruger #1. Any insight is appreciated

each barrel will be different in what it will shoot most accurately....start with 55grains and see how it goes from there. Your particular barrel may like them a little lighter or a little heavier, but 55 is a good starting point for the 1/12 twist

My Ruger #3 in .223 loves 52 grainers but will shoot most any 45-60 grain stuff pretty well

I am interested in this too, but with a slight twist. Not only the grain of the bullet which I assume is 55 grains or less, but also a good brand that shoots clean and is affordable. Yes, I know I should be handloading I am just not there yet. I have seen some posters having good luck with 53 grain and some in the 40s, but I have not seen a really good bulk deal on anything exotic other than garden variety bulk 55 grain. Thanks to the OP for a good thread and thanks for any input.

I hear that the steel cased Wolf is cheap, but dirty. I won't shoot steel cased stuff in my guns though

this is what I get when I want cheap ammo that still has good reloadable brass cases

First, are you sure your Ruger is 1:12? Quite a few early commercial .223 barrels are 1:14. Those are biased towards hellish fast light varmint-hunting hollow points but will stabilize M193 ball adequately in an International standard Atmosphere (ISA = 29.92" Hg, 59º F) or most any temperate zone temperature... not in an Alaskan or Minnesotan winter though. If you do have a 1:12 barrel you can probably shoot up to ~62 grain slugs accurately. The advice posted here to start at ball ammo's 55 grains and work your way up is good. For velocity you actually might want to go lighter.

The Ruger has higher accuracy potential than an M16, and you won't get max potential with issue ball ammo –– the spec accuracy for both is about 2 MOA and the #1 should easily be better than an MOA gun. M193 ball from a reputable manufacturer is a great way to shoot cheap but don't expect it to print to the same vertical point of aim as hunting loads do.

Hope this helps.

I tried some of the steel cased "TULAmmo" crap. It's crap.

The rifle that I had on the range that day was my "beater gun" and I was willing to try that ammo with that rifle. I had put about 60 flawless round of the Prvi Partizan M193 through it, and experienced malfunctions of every kind, including about ten short strokes, with the box of steel crap. I actually gave up after 15 rounds and tossed the rest in a trash can. The rounds were also flying all over the paper, so they're horribly inaccurate on the rare occasion that I function. I yanked out another box of Prvi stuff to be sure the rifle hadn't suddenly nose dived, and put all 20 rounds into a 3" circle at 50 yards without flaw.

Unless an American company offers it, and it's brass or nickel plated, I'll never waste money on steel cased .223 ammo again.

My own personal favorite has been the Prvi Partizan M193 in the little white cube-boxes.
Having said that, all of the Federal manufactured ammo I've tried, like the stuff Cracked linked, has worked flawlessly.

Try any of the lighter weights, up to 60 or 62gr hollowpoints (NOT 62gr M855).

I like XM193 or the commercial equivalent...my favorite is Lake City.

First, are you sure your Ruger is 1:12?

I thought a Model #1 varninter? was 1-9 twist. The commercial .223 50-55gr works pretty good in the Model 77. Don't know how accurate you want to get but first thing to check is barrel twist. If it is 1-9 try some Hornady 68gr BTHP if going out over 300 yds. They seem to kill pretty good.

Hognose, you could be right about the 1:14 twist. It's actually my dads gun that he bought for prarie doggin. We both reload, so working up something shouldn't be a problem. My AR like 62gr sierra's and i thought the ruger might like something lighter than 55gr. Will have to try a few out. Thanks

Again! Is it a single shot Ruger model #1 in .223? Pretty sure those are 1-9 twist.

Cdenmark, I'd have to check. It is a Ruger #1 single shot I'm almost positive it's not a 1:9. If it's a 1:12 or 1:14, I'll probably try some 52gr. sierra to start.

Sturm, Ruger & Co ad says 24" 1-9 RH twist for .223 caliber if you would like to confirm.

At shorter ranges the light bullets work just fine but if trying to kill something at longer ranges try the Hornady #2278 68gr BTHP. I'm still using Hogden powder I've had for years but I believe Varget is very popular. Probably gonna find somewhere between 23-24 gr of powder for that perfect load. If just target shooting think I'd just use the cheap stuff. As a rule I only use single shots to kill hogs. Beats grabbing by the hide legs and slitting their throat.

I was just shooting my C MP C barreled rifle tonight.

55 grain V-Max shoots ok but my 55 grain Hornady soft points over 23.8 grains of AA2230 work better.I have used 45 grain commercial Winchester Varmint 40 packs with very good results also.

I met someone a few years back that was shooting 52 grain SMK. Don't recall powder but he was shooting real nice groups with that round.

Most any 223 with a GOOD barrel should shoot 52-grain Sierra Match Kings, regardless of twist. I've had really good luck with even really fast-twist barrels with those, but they were good barrels and not rough ones.

Another good one to try is the 50-grain Sierra Blitz. These are varmint bullets made to open up explosively at 222/223 velocities. You don't want to run them at typical 22-250 velocities, but that isn't what they're made for, or anyway they didn't used to be. I have shot many thousands of the 50-grain Blitz and believe they are one of the best bullets Sierra ever made.

You can get bullet recommendations and load data, including component recommendations, from a Sierra bullet technician by calling toll-free 800-223-8799 during normal business hours for the Central time zone. Some of my high-power buddies shoot a lot of Bergers, too, but I don't think they fly any better than Sierra bullets for the likes of most of us.

Unless you're just shooting 50 or 100-yards and just blasting rounds down range to make noise and scare the birds, skimping on bullet quality (or any other component) is false economy and really doesn't save that much money anyway, when you put your pencil to it.

Sorry it's taken so long to get back to this. Just checked my dads rifles tonight and the Ruger #1 is a varminter with a 1/9 twist rate and his A2 has a 1/7. thanks for all the info.

Let us know your results once you do some shooting. The 1/9 should give you quite a bit of flexibility
