110 Grain Bullet Loads

[lsufrank]

Hello I am new to this forum. I have a Model 1 barrel on order in 300 Whisper and I already have my dies. I have looked all over the internet for load data and I have a question about loads using 110 grain bullets. The only 110 grain load data I have found is at Reloadersnest.com and in the Sierra Manual in the SSP section. The velocities for a 110 grain bullet shown are basically the same as a 125 grain. Using the reloading rules of thumb, you would expect about a 6% gain in velocity for a 110 grain load over a 125 grain load at the same pressure level. I do not see this in the data. Does anyone know why? I am only talking about supersonic loads. That is all I plan on shooting.

Thanks
