Thread: 16 inch 270win?

GRT suggests if your at 2925fps currently with a 18" bbl, cutting it to 16" will slow it down ALOT, somewhere in the vicinity of 2800-2815 depending on what powder your using, one would assume/hope if your seeing 2925 you would have to be using something like RL26 or Superformance to get there, If not your certainly going to blow yourself up.

No doubt plenty of others will chime in and you may already be aware but 2925fps from a 18" is well over maximum SAAMI pressure no matter the powder/combination used.
