Home Forums Hunting & Shooting Rimfires 77/17 wsm shorter is better

I've had this 77/17wsm for about a month (bought used) it came with a 24" barrel and my 100yd 6 shot groups were about 2.5" or so with generally only 2 almost touching. That was with a jard trigger at about 2lbs, #2 bolt shim and bedding the action and bedding material in place of the pressure bump at forend. I picked it up thursday from the smith where I had him cut it down to 20", put the scope back on today and went out to my bench and it was much better. I haven't compared velocity yet.
