What can anyone tell me about the chamber Remington used in the 40x? Im talking the older ones like 1959 range. Was it a match chamber?
 
I'm pretty sure all 40X 22 caliber rifles have match chambers. What I don't know are the dimensions or if they were ever changed. I am assuming the custom shop rifles were the same as the run of the mill target rifles. Although the custom shop barrels were probably lapped. Wayne
 
This thread needs a definition of "match chamber"

One man's "match chamber" (mostly meaningless term) is another's big, sloppy, hole. I know 40x will fire off-the-shelf ammo, so they're SAAMI min at the tightest.

I just read the SAAMI specs for 22 Match & 22 Sporting. I had never checked this before. Looks like the only difference is at the front of the case. Most match chambers will be a little shorter and tighter. They say nothing about leade angle. Therein lie a lot of secrets. Wayne
 
A new design.

For rimfire targets i had shot in practices they were uneleiveable at 50 ydsin very low ones about 15 0f them.and tey were not sorted out and they were shot useing wind flaigs. What i found was egignuter fluid was sloped all over the sideof inside of the cases if you scraped with a knife it would set it off the mutch extra could cause problem.
