I just finished up the 7mm RM article Wednesday, and sent it off. In the 24.4" barrel of a Mauser M18, 67.0 grains of RL-26 got a little under 3000 fps with more than one 160-grain bullet. The maximum charge of RL-26 listed in the latest Speer manual for 160s is 66.3 grains, which is also listed at a little under 3000.
But as I also point out in the article (which is about new powders and bullets) most new bullets these days have higher BCs than the typical softpoint flat-bases used for years in the cartridge. Today's bullets don't need to be started as fast to obtain "magnum" downrange ballistics.
I'm 50 1/2 and never used a 7 mm Rem mag but am a fan of the slower and more nostalgic 7mm. I haven't been checking the fire as much since I am working from home and doing a little more domestic work. Can't read the fire during lunch like I used to. Any way missed this poll until today.
Spent a few minutes last night looking at the latest Nosler data for LR Accubonds in 30-06. I'm interested in high BC 180-200ish gr loads for the 30-06. A Creedmoor for old guys. For some reason, went to look at the 7 mm Rem Mag data too, and was impressed with the possibilities. Impressed enough that I started to search for my first 7 mm Rem mag...
JB, what publication will the article appear and about when...want to make sure I have good reference material.
