First off it would be in the springer class. Second it is difficult to shoot off a rest, A: because it is a springer and B: contra piston system or sliding action to negat the recoil, I do not remember which. The vibrations set up give very strange results off a rest. Singel piston units of the same velocity area are even more difficuilt as they will jump right off the rest. There have been examples on other forums of slowing the 48/52/54 family down to get a much smoother firing cycle. Takes some real finess to shoot a High velocity springer off a rest consistantly. The Match type springers being much more sedat (typicaly under 600fps) are pretty decent off a rest. If you are just looking to start out and want to stay away from pcp or co2 you might want to look at the ssp units ( single stroke compression, no springs ) from ANZ 2001,2002 or FWB 600 series or RWS (100) or Walther. These show up every so often and run any where from 400 to about $900 currently. Bonus is these all have high grade triggers that operate in the 1-3 oz range vs the 54 in the pounds range. If you want stay in the springer class then the units to look for as a start FWB 300, Anz 280 ( I think) Rws 75 series, Walter had some out also. In a higher velocity Air arms TX200, I do not know what its trigger is like but it is a popular unit for field target compettion. Hope this helps.
