The standard contour barrel of the handi is still bigger that most rifles , the superlites are the only ones that i have herd of having a heating problem . when shooting p-dogs , more than one rifle is almost a must , last year i had 2 cooling while i was shooting the 3rd. and just kept rotating as they heated up .
I went through over 800 rounds in 4 days last year , that was between rim-fires and center-fires , with more CFs than RFs .
