SteveM : Please do the following test at 100 Yd -five shot group targets. Starting with a clean barrel, then after 50 rounds, then after 100 rounds , then after 150 rounds. If the Rem 17 Fireball will group under one inch after fireing 150 rounds with out cleaning the barrel, then I got to have one.It is common to shoot 150 to 300 rounds a day when shooting prairie dogs . My 17 Rem Sako rifle with 25 Gr bullet reloads has to be cleaned after 50 rounds to keep it shooting under one inch groups.
