I have a .17 HM-2 and want a second barrel for it in .22 long rifle.....my question.....can I use a Douglas XX grade .224 diameter barrel twist 1-14" or must I use a different diameter barrel? /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

I think you better use a specific rim fire barrel. Not sure how a lead .222 caliber bullet might behave in a .224 barrel. | |||

Green Mountains 22 rim fire barrels are Bore .218 Groove .223 just like everyone elses. You are looking at .224 caliber barrels for high powered rifles which are Bore .220 Groove .224. They are not interchangeable. They are NOT THE SAME CALIBER. http://www.gmriflebarrel.com/b...-blank-22lr-rimfire/ When I was a kid. I had the stick. I had the rock. And I had the mud puddle.

.22 LR also needs to be 16 inch twist. Craftsman | |||

1:16 is the standard twist for standard 22LR, but there are many variants. 22 short works best at 1:20 or 1:22. CCI Stingers with their short, light bullets favor the 1:18 twist. Subsonic ammo that use heavy bullets preform best somewhere between 1:9 and 1:14 twist. If you are simply making your garden variety, woodchuck whacker and varmint vanquisher then 1:16 is the norm.

Last one I built, a bench rest rifle based on a CZ action, I got the barrel from Dan Lilja. Owner tells me it shoots one-hole groups at 200 yards. John Farner If you haven't, please join the NRA! | |||

And some have rifles that are superbly accurate they always give the highest velocities lowest pressures and comes with the statement that they are the best rifle I ever had and I'll never sell it. Then shortly after making those statements one sees the very rifle for sale | |||

I have rifles that normally shoot 2 inch groups at 200 yards I sure if I fired 15 or 20 rounds I would have one ragged one hole group | |||

I also found the claim to be hard to be I even, but the family has extensive credentials in competitive rifelry, so although I suspect it to be a slight exaggeration, I have no doubt the rifle shoots exceptionally well. Thank you all for your most considerate comments; I can appreciate your scepticism. John Farner If you haven't, please join the NRA! | |||

.224 barrel will keyhole a 22lr needs 222 groove - and i would use a shilen 2 specific fast twist barrel, to allow for hyper accuracy for match bullets and SSS opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Do we have the same issues for 17 caliber barrels....meaning different bore/groove diameters for rimfire as opposed to center fire? /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

There are no lead 17 caliber bullets. They are all jacketed and to my knowledge use the standard .188 bore, .172 groove. Rates of twist are pretty forgiving in 17 calibers. They seem to run from 1-6 all the way to 1-12 but as a rule 1-9 is standard for the rimfire stuff and about 1-10 is standard for center fire. But I'm no authority on 17s. I just detonated a lot of blackbirds and gophers with my HMR. When I was a kid. I had the stick. I had the rock. And I had the mud puddle. I am as adept with them today, as I was back then.

Who you use is just like a CF rifle. As others have said, .22 rf specific barrel is required. Personally, if I spend the money on a new barrel, I'm going with Hart. ______________________ Ken A society grows great when old men plant trees whose shade they know they shall never sit in. --- Greek Proverb | |||

Buddies Sako Quad is Hart for the 22rf and 22 mag and 2 Liljas for the 17's because Hart doesn't do 17. | |||

In competition RF shooting you will find Shilen #1 and Benchmark #2 at this time. How about 222 groove on RF with a 218 bore. | |||

I know I'm going against the grain of all of the kids today Butch, but I still prefer button rifled barrels over cut. Especially for lead bullets. When I was a kid. I had the stick. I had the rock. And I had the mud puddle. I am as adept with them today, as I was back then. Lets see today's kids say that about their IPods, IPads and XBoxes in 45 years! Rod Henrickson | |||

For rimfire the button barrels like the Shilen, Benchmark, Muller, and a couple others work better for rimfire competition. I don't know why. | |||

One of Us |
I can't honestly say how many barrels I have installed over the years Butch. Probably the least in one year would be 10. The most would have been 30 or 40 in one year. So probably not over 1000, but decidedly over 600. 600 ÷ 36 = 17 per year which is a conservative estimate. I can however say for a fact that I have had far more consistency from button rifled barrels. I have installed more Shilens than any other barrel and very seldom had one that that misbehaved. About 10% of the barrels I have installed have been Harts. I have never had a complaint from a single one. I have also never had a complaint from a Ted Gaillard barrel. But, I haven't installed many. Perhaps less than 30. The majority of the time when I have gotten an uncooperative barrel it has been with cut rifled barrel. Perhaps it is just the luck of the draw. But that many barrels over such a long period of time, it's hard to dismiss that as chance. The one fly in the ointment is that a lot of the cut rifled barrels brought to me were small time makers who may not have the better steels and better equipment available to them that the big companies do. Those smaller guys also may not have had the experience to recognize and weed out and write off a bad barrel. It's also possible that a lot of them couldn't afford to weed out those bad barrels even if they did find them. Button rifling may be cheaper in labor to do if you are making hundreds of barrels. But if you are only making 100 barrels per year, cut rifling is still much cheaper in tooling. Once you have the drill and machine, you can do any twist, in any caliber and you can change bore dimensions on the fly. With button rifling you need a different button for each small change you make and buttons don't last forever. When I was a kid. I had the stick. I had the rock. And I had the mud puddle.
