Take that ANY day for 4 shots out of a 270 for hunting. Congrats!!
My 270 was a 700 BDL and loved 150 gamekings over RL22 @3000fps. Same accuracy as your getting.
150@2900 will take anything in lower 48 out to 600 easy and wont break your shoulder or wallet in the process.
I like the 270 for a beginner anyway, one that I've recomended numerous times over the years to kids and women, or anyone who didnt want to shoot much over 600.
