If I enjoy the upcoming Extreme Rimfire Silhouette Benchrest match I can see me wanting to upgrade my current 40x 22lr BR rifle. Here are my ideas and a question or 3:
Plan A: I will open up the bolt face using a 16/64 end mill. I will leave it at the current 22 LR depth. I will then chamber up a 22 mag bbl. This way I can swap the 22mag or 22 lr bbls back and forth and not have to change the bolt. Do you gunsmith's think an unmodified 22lr firing pin will set off the 22 mag cartridge ? Any issues with the smaller 22lr case head in the 22mag bolt face diameter ?
Plan B: The above bolt is a PTG. I could beg and plead with Dave to make me another bolt head and raw firing pin and then I could properly fit them to the 22 mag cartridge dimensions. He might not be amenable.
Plan C: Buy a used complete Remington bolt and fit it to the 22mag.
Plan D: 17HM2 bbl and don't mess with the bolt. I will probably try this first.
I know I would have to modify the loading ramp/ejector.
