Been thinking of buying a .177 pcp and want to go with a bullpup. Since I already have .22 FX 400 and .25 cal Cricket I am wanting to get a light, easy to maneuver bullpup in .177 which will be used primarily for bird shooting at farms from a truck. I see lots of talk about the .22 and .25 P15's but not too much on the .177. Are they a decent shooting pup and what kind of power and shot count do they get? Really don't want to spend over $500 so the P15 is what I'm looking at getting. Not sure I want to pay extra for a prettier stock, but I might. Really just wondering if the .177 in bullpup form is worth it or just get a .22 to go with my Royale.
