The following is just my observation and opinion. (Worth exactly what you paid for it.)
For many years, I have used H&N Field Target Trophy pellets in .177, .20 and .22. They have always performed well. I decided to try .22 JSP pellets of the same weight as the H&N. The first thing that I noticed was that the skirts are thinner, softer and not very round. They also seem smaller when seated in the barrel. They shoot a little to the left and I get an occasional flyer. What I mean by that is 1 out of 10 will be slightly out of the group. It could be me. I haven't shot them any further than 15 yards. If I didn't know better, I would be happy with them.
I found a partial can of .22 H&N Baracudas. I decided to try them in my HW30. They hit about 2 1/2 inches low at 15 yards, but group well. I don't know what the velocity is, but it takes awhile for them to make it to the target.
