nralifer Report post Posted December 19, 2015 I had a similar problem with several calibers. Was using Fed 215M primers. Switched to WLRM primers and the muzzle velocities were a lot more consistent. The chrono could be the problem, but if you get consistent velocities with another load or rifle, the chrono likely is OK. I use both Magnetospeed and an Oehler 35. I can recommend the Magnetospeed highly. Only potential downside is the attachment to the barrel influencing the harmonics and point of impact. More likely with a thin long barrel. Be sure to check the bayo between each shot and be sure it is tight. Works well with both copper jacketed lead core or solid copper bullets. Share this post Link to post Share on other sites
nralifer Report post Posted December 19, 2015 Had another thought. You could buy a box of some high quality factory ammo and compare it to you loads for muzzle velocity consistency. Share this post Link to post Share on other sites
willhunt4coues Report post Posted December 21, 2015 I had a Pro Chrono do the same thing to me. When I got my magnetospeed I was only 10fps ES and on the Pro Chrono I was 80 fps. I actually threw mine away. LOL. Shoot at long range 500 and see if you have any vertical disbursement. 1 Share this post Link to post Share on other sites
