I jumped into the PCP game with a .30 Wildcat but have both .177 and .22 springers. I went right to the .30 for the power. I have a coyote problem at my cabin and wanted the extra power to deal with them with out having to go to a dedicated big bore slug gun. I am planning on adding a .25, .357 and .45 to my collection lol. Yes sir, right down the rabbit hole we go!
Not hard to slide down that rabbit hole. 22,25,30,308,357 in house. Don’t know what 30 you have but check out Nielsen Ammo for swagged slugs. My rainstorm.30 loves them and the hp opens up very well. Longer flatter shooting than the 44.75 and 50 jsb and a lot more energy down range, though the pellets definitely have their good points. I also shoot rick Morrill’s 67 grain bbt and recently got some 62 grain swagged from dale riggert to try today. Have no love for coyotes myself. Good hunting.
