That's about the same results I got with my S400E, Greg, 23 fpe with CPH's and 27 with the EJ's. Very consistent, flat shot curve in that rifle, and very good accuracy out to 30 yards, that's as far as I tried them. Of course, that was 16 gr., so if the ones I had weighed the same as yours, probably closer to your numbers. I've heard lots of complaints about the EJ's, but they've always treated me well.
I have a suggestion for your Talon, try a heavier hammer with the PW turned down. Might be able to turn the TH down too. I bet you'll be able to keep the same or better velocity, while improving your shot count. And no, you don't have to order a custom hammer from Tony. Check you local hardware, big box, or NAPA for a 1" od x 3/4" id x 2" long bronze bushing. That should be a drop in fit for a hammer replacement, and will weigh about 75 grams. Your stock hammer should be somewhere around 50. It'll probably cost less than $5, and I think you'll be surprised at the performance difference, especially when you drop the .22 barrel back in. And if it's too heavy, you can always cut it down a little at a time. Or you can wait, and I'll send the one I've got sitting here in front of me with your pellets :-). Later.
