I took out my .25cal S510 Ultimate Sporter out for the first time yesterday to sight it in. Had it sighted in at 30 yards within 10 shots and it looks like it's going to be a somewhat boring gun to shoot.
Approx power levels with 25gr JSB Kings are:
PL 5 - 869 fps, 42 fpe
PL 4 - 831 fps, 39 fpe
PL 3 - 721 fps, 29 fpe
PL 2 - 533 fps, 16 fpe
PL 1 - 287 fps, 4.6 fpe
I'm thinking for the backyard pesting I will be using power level #3 a lot so I might sight it in at 20 yards with that setting and recalculate where my high power setting will be. Currently the #3 power setting is 1/2" low at 20 yards with my #5 power setting zeroed at 30 yards. A 20 yard zero on power level #3 would have it shooting 1" low at 41 yards with 23 fpe. Not too bad for my needs. Looks like around 3 mags per fill at high power. More at the lower settings. All in all, I'm happy with it. Now I just need to find a .25cal single shot loader for it. CARM has them, but not in .25cal.
