Does modifying an existing one that was gathering dust count? I built two folders using the Archangel stock from rifles that were just sitting in the safe. One of the folders that shoots sub 1/2 MOA seems to be getting more trigger time than my previous favorites, following me everywhere I go - INSIDE my laptop computer case!
Two sort of like a new 22 rifles doesn't seem sufficient, reading it in black and white. Would a 22 airgun count? With the price of ammo, I decided to jump on the runaway airgun train and bought a PCP (Pre Charged Pneumatic) air rifle that is very accurate out to 50 yards. I learned that the wind has significantly more influence on a 22 airgun "bullet" than a 22 LR. The best indoor group was sub 0.2" at 16 yards and it shoots sub 1" fairly regularly outdoors at 50 yards if the wind cooperates.
As for the cost of ammo, the most expensive pellets I bought were JSB brand @ 4 cents each and the cheapest were Walmart procured Crosmans @ $6.24 / 500 or ~ 1.2 cents each. Happily the Crosman pellets often equal or best the JSBs depending on the day as long as I look for dented skirts. I am going to try weight sorting some eventually.
I enjoy shooting the airgun just as much as my 22 rimfires and in some ways more. No need for hearing protection. I can shoot in my yard or in my house with nothing more than a good bullet trap and it is 90% cheaper to shoot. There is a steep entry cost for refilling PCP guns, but after that initial lump of cash for a tank or a compressor, you are shooting for just over a penny per shot from now on. You can get by with a hand pump if you aren't shooting a lot of rounds, but pumping gets tiresome very quickly. There are airguns out there that shoot around 1 MOA at 100+ yards and offerings in larger diameter bores from 25 up to 70 cal, with some significant muzzle energy for hunting on the big bores.
