Some take a fired case, deprime it and insert a screw shank, then coat the case with flitz or JB bore compound, then spin it chucked in a drill. I use a large bore mop wrapped with a patch, coated with JB bore compound, with a piece of cleaning rod attached and chucked in a drill... either way will work and will reduce or eliminate stuck cases(failure to eject). Making sure the chamber is clean and dry will also prevent stuck cases.

On a related note, H&R is well aware of the history of FTE and have switched to mechanical extractors on some calibers. (.22-250 and .204 ruger).

A  fired case, remove the primer, and incert a small bolt from the neck side of the spent cartridge then add a nut and washer on the back end, use a drill to spin the case with the jb paste on it. Cordless drill works the best and don't over due it you just want to polish out any rough area that will keep the fired case from ejecting. That is if your having trouble with cases sticking after they are fired. Mine mostly stuck after being reloaded, the first shot from new factory ammo for the most part didn't stick. I used a straight lenth of steel brake line with a slot cut in it and some fine paper in the slot with a slow speed on the cordless drill, before I read about using the spent case mathod.

dannyk I think you hit the nail on the head......reloaded casings is when the most stuck problems happen :( ......Factory ammo works almost perfect for some reason.... :P  It must deal with casing expansion alittle on the reloaded casing and causes it to stick more....I bet the h&r factory hates to here about reloaded ammo casings sticking in handies......I know people that reload will beg to differ.....but somethings goes on with reloaded ammo at times

As a reloader, I must beg to differ...   8)

I'll bet you can find more than a few instances of stuck cases with factory ammo.  It might happen more often with reloads, but that could be caused by several factors.

The only reasons reloaded cases would result in sticky extraction are:
  1) loaded too hot (not uncommon as lots of reloaders are after maximum performance)
  2) weak ejector spring (a likely cause of trouble, especially when combined with reason #1)

A possible third cause would be dirty brass, but I think that it'd have to be pretty dirty before you starting having problems.

I'll also bet that the internal finish on a $200 rifle isn't up to Weatherby standards.  This 'rough' chamber combined with an inadequate ejector spring and a hot handload is a recipe for stuck cases.

The newer guns with the mechanical extractor probably won't have this problem at all.

I wonder, could you take a jag with a large wad of cleaning patches and a pinch of polishing compound, chuck it in a drill and give the chamber a quick polish?

Works for me.

I've only had one stuck case, was with factory .243 ammo, my fault cuz I forgot to wipe the chamber after cleaning at the range. No stuck cases in any other Handi in hundreds of rounds after the polish job. :wink:

I want to pass this by the people on this forum who by all streches of imagination have a lot more expertise than myself on this subject. When reloading, you use the brass that you shot out of your gun, (makes sense)the brass kinda takes on a foot print of your chamber, it swells or streches to conform to your gun (first fired brass) once it has been formed to your particular chamber it will have a snugger fit in the chamber, when it is reloaded, and fired again there is more of a chance for the brass to stick, thats why a polish job of the chamber is in order. Correct me if I am wrong. In my experience with my ultra in 223 the factory ammo (Federal) most ejected but not all, the reloads 25.5gr of H322 had a much higher incidence of sticking, (and yes the chamber was cleaned) this was all solved by a polish of the chamber, haven't had one reload stick since. Any thoughts?

I'm just getting set up to reload for my Handi and most all that I have read says to full length size for them. This should make sticking because of being shot in the same chamber before a non issue...or at least that is what I understand.

btw The only two stuck cases I have had were with Winchester white box 45hp, go figure. Black Hills ammo goes through it just fine.

I have only had trouble with Winchester ammo as well - Federal seems to eject from my .243 without any issues. I have not polished the chamber yet so will do this and see how it handles the Winchester.

in my 223 i have shot only hand loads and they are loaded at max.i polished the chamber with flitz with a fired case and have very little trouble with stuck cases.once in a great while will one stick.if you hand load for a handi rifle you should full lenght size your brass each time and that will help alot too
