I shoot a Savage Striker w/ 16" barrel in 22-250. My moderate handloads w/ 35gr Varget and 50gr V-Max are moving 3300fps. I'd venture to guess that you would be rather close but the 55gr load and 15" barrel (I think that's what you have) may just fall under the limitation.

UK...you guys measure everything metric, right?? Shouldn't you be looking for meters per second??
