"I am after something to get my feet wet." "so I can go out and shoot to see if I even like it."
Howdy , These guys as always give excellent advice ...But ...I take it that you are very new to all this ..
You mentioned you have a 260 Rem in a XP100r .I'd suggest to you , to see if the gun will shoot good groups at 100 yds .I'd have someone sweeten up the trigger , load the lighter bullets , and play some before spending a bunch of money . The 260 is a very good cartridge , and will shoot way out there .
Just my 2 cents
