When new, my .22 HW45 was getting 6.0FPE or very close to it. At that time I had lots of Beeman FTS pellets which the H&N manufacturer calls Field & Target Trophy. I had a heavy lot that weighed 14.9gr and hit 425fps.

My .22 HW45 is now on it's second spring. I changed the original at approx 7500-8000 pellets but I could have got more out of it. The spring change was part of my review. Anyway, the new spring has seen around 6000 shots and is now doing 415fps with 14.2gr RWS SHP (5.4FPE).

Cheers,
