When testing some new loads with a Browning Citori 26"full choke avg FPS 1289. Retested last night Rem 1100 32" full avg 1368. I'm trying for a avg. of 1325 7/8 oz load 7.5 shot
If the targets disappear they're fast enough-like buying a MB SLS--fast enough to get you a jail sentence or killed in any of the 50 statesI can't find one for 700x so just playing around with some modified 1oz load data just found it odd that the speed changed that much from one gun to the next. New post on reloading
Wouldn't ported barrels also modify the speed?I believe testing is done with 30" barrels at the Factory to get the published fps. For each additional inch add 10'/sec and each inch less than 30" you subtract 10'/sec for what you should be seeing for speed. Don't have any idea where I saw this, but it was a long, long time ago. I believe it to be fairly accurate. However, some of my beliefs have been screwed up before......
