[QUOTE="CaptnC, post: 1943945, member: 101755"] Just built a 10.5" 6.5 Grendel pistol, that should next month become a suppressed SBR. But for now it's got my suppressor from another AR and is in a pistol configuration. I actually have a few questions; Will swapping suppressor's change the load I have for it? Both suppressors are made by the same company and same model. I know the reduced barrel length, reduces velocity but I have made some odd observations. Looks like 2200fps is all I will get out of my barrel. Regardless of bullet and powder combinations. 90gr TNT, 100gr NBT and 107gr TMK all came in 2100fps to 2200fps...the SD and ES were so close, just looking at the numbers on my Magnetospeed you would think it's a tuned load. Is load development senseless on a short barrel? Finally, I attached my Magnetospeed to the suppressor. [ATTACH type="full"]204230[/ATTACH] Of course I had to change the settings to get it to sense the bullet fight. How reliable will the readings be using the Magnetospeed in this fashion? [/QUOTE]
