I read somewhere on the net that when Kimber test their rifles for accuracy, they'll normally wait a good 4-5 minutes between shots to allow the thin barrels to cool down. That, plus the fact that you've shortened the barrel, and put on a suppressor...the barrel will heat up even quicker. Not to mention the weight of the rifle. Apparently the ultralights require different technique to a heavier/longer barreled rifle.
