How about an A-10, just for plinking
Honestly I really don't know. It would depend on which competition. I don't have only one favorite. CAS would probably be 1875 Remington and Scholfied(sp). My heavy octagonal barrel Rolling Block and probably an 1881 Marlin. Three gun-handgun would be Para or Springfield 40 cal with full ambi controls; Jackhammer or Gordon CWS shotgun; rifle-not sure possibly left hand Blaser or Dakota in 300 Win Mag. IPSC; I like my full ambi 1911 ( not a gamesman) and my Benelli M121. As for subgun matches, it's hard to shoot fut it's also hard to beat the classic lines of a Thompson. BTW, I saw somewhere on the web that Dillon's personal minigun and mount was for sale. don't know if it's bs or not.
