I got my first airgun in 1972 and it was a .177. Every air rifle and pistol that I purchased between then and November 2024 has been a .177. I’ve been perfectly happy with ,177. Then in November I purchased a 250z .22 and I liked it, but it was more the rifle than the caliber. Then I purchased the .25 Ghost, followed by the.25 TalonP. The change from hearing a dink when I hit the steel back plate to hearing a thwack changed everything. Thank goodness the BRK Sonoran only comes in .30. The thirty is my favorite caliber now. Everything about the .30 is better: wind bucking, down range ballistics, easier to handle the pellets, pellets never seem to have deformed skirts. If you approach it like I do, the cost of shooting .30 is very close to the cost of shooting .22/.25. When I purchase ammo I pay attention to the cost per tin. If I purchase a tin of JSB .22, .25 or .30, the price per tin are all within $1 of each other at DonnyFL. That makes them all roughly $18 a tin. I ignore any other info on the tin other than weight and caliber. I ignore the quantity per tin, too much math takes the fun out of it. In all seriousness, I don’t shoot my .177s much anymore, but that’s more to do with the guns. It’s hard to beat 500 .177 pellets per tin.
