Technically yes. You have to load higher pressures to achieve the velocity you are looking for, however this is due to the coating. Some people have had to crimp the necks to A) hold the bullets in when casing are loaded to make volume, and B) to get the pressures necessary. Its a trade off. Regular bullets higher pressures at reasonable loads, or higher velocities and more powder required.

If you are at max speed and pressure with a non Moly bullet and then you load and shoot Moly bullets with the same amount of powder you will get less speed and it will take more powder to get the same speed as the un coated bullets. I do not think that you will be able to get more speed than an uncoated bullet simply because the case will run out of room to add more powder
range it,check the wind, dial in correction, aim and only one shot
Most guys that are coating bullets have left moly and gone to the boron nitride. Lot easier to put on the bullets. Go to BR central and 6mmbr and search for articles and info.
You can also send the barrel off and have a melonite coating put on it. Article on www.6mmbr.com on that. Joel Kendrick is top 600 yd record holder has over 5000 rounds thru his gun using melonite and it is a wildcat which is basically a 6x44. He is reporting no erosion and faster speeds.
With a 9 twist you can also go to the BIB flat base bullet which is a 108. He also has a 118. I have been running the 108s at 3130 fps in a 6mmBRDX (ack Imp) in a 9 twist. Randy Robinett (6mmbr and BR central) is owner of BIBs and can answer on the 118 in a 9 twist. The FB bullets can be run faster with less pressure in the 9 twists compared to the 8 twist.
In my experience you really don't gain much with moly and if you are not familiar with it. it will frustrate you. one thing is for sure if you clean your barrel completely it will take 2 or 3 shots -- to recoat the inside of the barrel with moly to get the groups back. and you will not get more speed just because it is moly coated. you will get less if you use the same charge. however with moly you can get by with more powered due to the less pressure that the moly bullets create.
Now back to this George thing. Are you using the same kind of powder and the same charge?? even the primer? and is his barrel the same lenght? and his barrel cut rifled or button. As far as speed goes their are several things that can make 100 fps differance. Even the condition will make some differences. Each thing i have mentioned could effect speed a just a couple together would get you 100fps one way or the other.
My big question is if your gun will really shoot a certain load don't worry about 100fts just know your gun. dial it in and kill it. 100 fps is not noticable until you get out past 300 yards or so.
