.300 Ultra Mag Wildcat ?

This has been ask before. Many think that the only way to improve
the 300 RUM is to neck it up to 338. The 300 RUM is so big with low
body taper and a fairly sharp shoulder, that there is little increase
in case capacity to be gained. I think it's just right the way it is.

What I'm looking for is a higher bc bullet. There is much more to
be gained there than by a slight increase in velocity. When that 220 grain
bc=0.9+ bullet comes along, I'm going to have a 300 RUM built that will
handle that much bullet. I'm wanting to take a feral pig at one mile.
The 300 will do it but the bullet is more important than the case design.
 
300 Tomahawk=Darryl Cassel

Try: PrecisionLongRangeHunter to get a hold of him. A search will on LRH will reveal contact info.

300 RUMBO= JMDEM here on LRH is the designer behind this design.

Try Autorotate (me) by March on real world results on the RUMBO hopefully :)

Dave Kiff at PTG make a reamer for the AI 300RUM. I've seen it for sale at Midway. Might get a 50-100fps boost and maybe better brass life, so I've heard.
