Another good point, that was something I was thinking about as most 22's you buy today do have a sporting chamber and just going from a sporting chamber to a match type chamber can have a good effect on the accuracy.
When the bullet is loose in a sporting chamber, nothing comes into contact with the nose or even the first driving band, so it is possible for the round to enter the rifling at a slight cant which it will stay at all the way thoiugh the barrel, exiting the barrel with the same slight cant which equils a flier.
It is for that reason that I plan on re chambering most of my 22's with the EPG match reamer. I have already done it to one, I need to deepen it as too much of the bullet is now in the lands, I want the land to just make a little contact with the first driving band and whatever contact it makes with the nose of the bullet.
My Savage BRJ will be the next rifle that I will re chamber. It will also be threaded as will the action. My gunsmith friend will do the threading as he is better at it than me, he also puts a special cut at the end of the barrel and back of the action that acts as a lock. The more I can have the action and barrel act as one solid piece, the better the accuracy will be.
If the results are good, I'll save for a Benchmark barrel and change out the stock Savage barrel, but if the rifle ends up shooting better than I do, I'll leave the stock barrel, I have a good one on there now.
I'm kind of hoping it shoots great groups with the stock barrel, then there is nothing but some time invested, I already bought the PTG reamer with the rotating pilot.
The other consideration is just how accurate do I need the rifle to be. If it shoots in the .1's, can I really shoot better than that ? I'm shakier than I used to be due to meds and an injury, so the stock barrel may be the ticket, right now in calm wind I can already shoot .2's and consistant .3's, that is really almost good enough, I'd just like to get rid of some of those pesky fliers that are not my fault and I think re chambering will go a long way in helping.
You made an excellent point :bthumb:

If I got a Svage with a bad barrel, I would hang a custom tube on it for sure.
