.22 match chamber specs

geeguy

I need the spec's for a .22LR semi-auto pistol "match" chamber for shooting standard vel. ammo (Ely, CCI, Federal).
This is for a Clark STC barrel on a S&W 41. After 3-4 shots there is no ejection until the chamber is cleaned, then works for 3-4 more. Tried all different ammo and barrel assembly on 3 different frames, same result. I had thought the best way to proceed was to measure the chamber before sending it to a "smith". Problem is I don't know the spec's and reading some reamers they have different specs for bolt rifles then for pistols.

Any recommendations or specs (I'll try reading with a pin gauge)would be appreciated.

geeguy,

"Featuring Clark's EXCLUSIVE match chamber and crown, 5 1/2" length and offered in three great styles."

Personally, I'd call Clark's Customs Guns on the phone and explain the problem to them and see what they have to say. You shouldn't have to do anything except listen and maybe send the pistol back to them for examination.

Best.

These are some of the more popular chamber measurments for .22LR I would recommend that you call CLark and tell them about the problem.

Nononsence: Tried calling Jim Jr. (I have purchased several guns and parts from them over the years), and they will not give any information other then "send it to me", which is $120 for both ways. As a side bar, this is not the same Clark of years ago. They built me a new .45 last year and had several wrong parts in the gun, upon asking for the correct parts they again sent the wrong ones. I ended up changing the parts from my own stock to make the gun work properly. They used to be easier to deal with in the past, as now the answers all seem to be the same, send it back.

So before I send it back to Jim I wanted to check it myself.

Mooseyard: Thanks for the information, I will check it to these specs.
