rechamber Handi Rifle 223 to 225 win
« on: August 05, 2012, 04:23:35 AM »
Need Min. & Max. Headspace dimensions for this rechamber.  Tryed to get on Saami web site but cannot get in to get info. Has someone got the info to share? Would like drawing so can make own headspace guages.

The 225 Winchester is a rimmed case. When you cut the chamber, you will also cut the rim relief. Run the reamer in until you cut the rim depth to .001" - .002" deeper than the rim thickness. The rim thickness is .049" thick so cut the rim depth to .050". You will be head spaced properly. the other way is to buy Go gage and No Go gage for the 225 Winchester. As you get close to the proper depth, but still short, drop the go gage into cleaned out chamber to see if it will close on it with the barrel on the action. Take it back off and keep going deeper and refitting until the action will close with the go gage in the chamber. Once you do that, check the no go gage to ensure the action will not close, if so, you have it properly head spaced.

To be sure on rim thickness, buy your brass ahead of time and measure the rim thickness. It should be .049" thick. Also, the shorter you cut the chamber, the less case stretch you will have, so you are better off to have the chamber just deep enough to close your action on and no deeper. Remember, if you cut it too shallow, you can redo and cut it deeper, once you cut it too deep there is nothing you can do, except cut a chamber for a bigger cartridge. So be very cautious when approaching the proper depth.

Good Luck and Good ShootingSorry, After rereading your post..... I thought you wanted to know how to cut a chamber, not make head space gages. If you use the first method above, you will not need head space gages.

Good Luck and Good Shooting

My 223 is a 225 and I love it.  Makes those 60 Hornadys fly right along and into less than in inch at 100 yards, too.

j Stuart WELCOME to GBO!!
 
Laotto222, has given it to you straight. When rechambering a action like the single shot handi, these gauges are NOT needed. Simply ream the chamber (as he outlined) until the rim cut is .001 - .002 form the rim thickness. Dont make this any harder than it has to be, with a straight edge, stop reaming when the case fits flush, then after you have checked to be sure the case your using is at spec, remove an additional .001 - .002 and your done!!

MANY of us have done this multiple times.

It really has nothing specfically to do with the rimed case either... for example, when reaming a rimless, you do the same. You ream to a previously checked case thats within spec, to flush at the base of the case compaired to the barrel breech. Then a .001-.003 more and that one is done.

Another example,  when reaming a bolt action, you cannot easily check if the case head is flush with the barrel breech. To further complicate things, on some cases the barrel breech and case head, being flush means nothing, as the bolt shrouds the case head... So, in those cases when re chambering a bolt action the "go - no go" cases are needed to properly chamber. (Some others too) Same for say a Hi or LO wall winchester. There actioms designs inhibit easy measuring of the headspace. (This is what your doing with the last bit of reaming, setting the head space.)

IMHO, this is a excellent preforming caliber and re chamber in a handi rifle. I have long considered it myself. You will get 22-250 preformance in a good rimmed case. One which I prefer in a S.S. such as our Handis.
