I just got my suppressor a few months ago and I love it. I was shooting a 26 inch barrel and cut it down to 20 inch. the rifle is a Remington 700 in 308 the rifle has shot very good for me and not so good (155 sierras) but after the suppressor and cut barrel it actually shot them pretty good. I believe in trusting ones ammo and I just do not trust those bullets as much as the heavier ones. I am starting all over again in load development for this rifle and I planned on shooting with the can on to find the sweet spot, is this correct or not? I will be doing a ladder test and my first thought would be, Duh! shoot the ladder with the can on but just want to get some input from guys that might have more experience with that. thanks in advance. sorry if this is not the right place for this question I just found it the most appropriate
Accuracy node with supressor

If you are primarily shooting suppressed, do your load development with it on. Only time I do not suggest this is initial load testing with subsonic rifle loads.
Yea I will not shoot this rifle without suppressor. Might as well do my load development with the can on. Thanks for the info
I do load development with ladder testing without suppressor and load a little lower to allow possibly higher pressure with suppressor. Also taking into consideration temp that I will be shooting at

I was under the assumption an extra 20oz hanging off the end of the barrel will change the overall harmonics of the barrel, thus changing the nodes, no?
I suggest you read the references to the work of Chris Long in the latter half of this thread. Chris created the Optimum Barrel Time load development method, which involves correlating the dwell or "barrel time" of a bullet to a charge weight with the goal of pinpointing an accuracy node. A couple of members of The Hide have contacted him directly to ask the exact same question you are posing here.
The short answer is that a thread-on muzzle device tends not to affect the reflected "shock wave" that is responsible for the existence of accuracy nodes. The weight of the device certainly will change the barrel's bending moment, which changes POI, but not the location of the accuracy nodes.

I had to tweek the load for my AR when I screwed the can on but my 260 shot the same. My 16" bull barrel AR had a 1.5" POI shift and my 24" varmint taper on the 260 had a ~2" POI shift at 100 yards.
Like said above, I would do the load development with the suppressor on.
