Re: 300RUM to a Tomahawk?
I didn't know you were talking a 34" barrel. I thought we were talking normal barrel lengths. The 300 RUM is very accurate and very consistent with top velocities from what I saw on my range. So you can predict this one with fair accuracy. Looking at some of my data out of several 28" barrels they run consistent with top velocities around 3340 fps with the 190 grain bullet. With six more inches barrel length giving it 30 fps per inch makes it 3520 fps. Could improving it make it 3600 fps, maybe. Figure he could have had a hot load and a fast barrel and yes with a 34" barrel it could be possible. I guess from now on I need to ask rifle description before I answer. I always just assume a normal rig unless somebody specifies differently.
Predictions are difficult, especially when they involve the future
