A good PCP would be a step in the right direction from your Rhom for precsion target shooting and the price can vary considerably with age make and type.
Good makes to try to see what works best for you include Feinwerkbau, Steyr, SAM, Walther, Benneli and Morini - all of these are capable of the best possible scores leaving the shooter with the excuses for not doing better !
......but, just because one type of pistol works well for your friends or clubmates, does not mean the same will automatically work as well for you, so you really do need to try before you buy as many as possible to see what you feel the most comfortable with.
Rossendale Target Shooting Club. Every Tuesday and Thursday evening 7 - 10pm.
