22LR chamber reamer question

[Westex]

I know there are a lot of different chamber reamers for the 22LR . I am building a Tikka T1X with Shilen ratchet barrel and borrowed a friends Manson 22LR reamer it did not have chamber deminsions with reamer but it just says match on the reamer . chambered it up and it shoots good but it puts rifle engraving on the bullet pretty far down and makes for hard chambering on certian brands of ammo . I purchased a another reamer from Midway and it was Anshutz revision A PTG . I looked for deminsion chart and can not find revision A anywhere . anyone know what revisions were done ?

I think the engraving on your first reamer is good.

The pushing of the bullet into the lands is common with "match" chambers. My CZ factory match barrels are setup that way.

The barrels are chambered to engrave a certain amount on the chosen bullet. Just find the right brand of bullet it was set up for by the gunsmith and then find the right lot. This is the way

I had a BSA mk5 martini action target rifle.if you chamberd a round and ejected it you could not chamber it again..set up tight and very accurate.

PTG can furnish prints for their reamers. There are many different match reamers for the .22 LR and nearly all of them engrave the rifling and are designed for bolt guns. If you are experiencing much harder chambering with some brands than others, it is likely because of headspace. Different brands have slightly different rim thickness, plus slightly different radius on the bottom of the rim, causing the rim to protrude a different amount from the breech end of the barrel. Most serious BR shooters use a reamer specifically made for a particular brand. If you are going to use various brands of ammo, you need to headspace it for the thickest rim.

Some 22 reamers do not cut the headspace. The reamer just cuts the body and throat so you can set the amount of engraving to the ammo you plan on using. If the barrel needs a headspace counterbore, it is done with a boring bar. Again, setting the depth to the ammo. Lots of vooduu in smallbore.

I have a good friend who is a barrelmaker and a Schuetzen competitor. He is now chambering his own rimfires with about .030" of jump and it is working very well for him. This in his falling block rifle. I use a 52C spec reamer which engraves most bullets quite heavily and it works very well for me. I agree, there is still some voodoo in rimfire! WH
