H&R Ultra 223 twist rate?
Anyone know the twist rate on the Ultra 223?
Have heard all the new H&Rs have micro-groove barrells? Has anyone bought or shot one made in the last year or two? The website is a little thin on information about these lately. Was thinking about getting one for a "project/fun to mess with" and work up reloads for, inexpensive rifle. Information about the new ones is good and bad, depending on which forum or article you look at. Thought I would ask you guys about the new ones and see what you think. No-one around here has any new ones in stock to look at and I don't want to spend money ordering one if they are now junk. Would like to hear the good and bad about em Thanks |

Best way to determine you twist rat is to read the FAQ page in the H&R forum on Greybeard Outdoors. Your rifle is either a 1:12 or 1:9 as those were the two twist rates used in all H&R rifles. I know my Ultra Varmint has a 1:12 twist, as long as I stick to 55 grains or less it's pretty accurate.

You could always find out the twist rate yourself for sure with a tape measure and a cleaning rod..

Marlin gave up microgroove rifling because users didn't understand the system.
Microgroove is are more sensitive to bullet hardness and bullet diameter.With the right bullet microgroove can be very accurate !!

"Was thinking about getting one for a "project/fun to mess with" and work up reloads for, inexpensive rifle."
In this scenario, I'd advise you to look at another venue. My 15 year old NEF break action .223 does OK with 55 grain bullets-around 1 MOA. 60 grains run in the 2+ MOA range and anything heavier than 60 is sort of "iffy" but generally in the 3(or more) MOA range. In addition, you'll have more difficulty getting good groups from a platform that requires you to lift the rifle off the bags to reload and then re-seat onto the support. More?? OK. I found that factors as seemingly insignificant as how you close the action will affect POI or group size. Spend whatever it takes to own a bolt action for your experimentation. |

Put a solvented jag on your cleaning rod and stick it into the rifling preferably from the chamber end. Put a dot(Sharpie) on the rod at the chamber end and the handle. Push the jag through the barrel for one complete turn of the handle end dot and mark the chamber end again. The distance between the dots is your rifling twist.
Way easier to do than type that. snicker.

You can get awfully close with a cleaning rod and a wire brush. Get the brush down in the barrel and mark the top of the brush. Pull the rod and let the brush turn by only touching the handle. When the first mark come's on top again, mark again and measure between the marks!

You'll have a tough time finding anything other than "new" old stock. Production ceased quite some time back. GW

"Have you tried 40-50 grain bullets?"
No, this rifle has been relegated to Grandkids' use and is basically a training tool these days. |
