+- .005 is acceptable and sometimes is as good as it will get for any bullet. The ogive of the bullet and the amount of pressure it takes to seat the bullet will change bullet to bullet. I load about 35-40 different bullets and alot of them will fluctuate that much and more. I have found that the RMR MW is the most consistent with COL’s and it will be off +- .002. I round off my COL measurement to a .005 ( 1.125 or 1.130 ect.) there will be no change in pressure or accuracy or function, unless you are already to long or short. Set your calipers to .005 and look at it and see the difference. good-luck Brett

I use BE-86 for my 9mm. I load 3 of the MW FMJ’s. 115,124,135. @ 5.6gn. ( +- .1)for my best accuracy. 1.100 COL. I don’t use a chronograph I estimate some where 1150-1170 with a 5″ barrel.

I’ve just started using these 124 MW. I’m a big fan of BE-86 powder. Since I shoot for the accuracy , I shoot at about 95% of max alliant data. I found great accuracy at 5.7gn. at 1.100 COL. using a CZ Shadow 2, a 5″ Prodigy, and a TSO, ( cz tactical sport orange). I will drop it down to 5.5gn. and try that next. I am very impressed with precision of these bullets, and have found they were one of the easiest bullets to load that I have. Great job Jake. ( PS just ordered another 1000.) Brett
