Once again Ruger and Hornady found a way to make a "new" cartridge.
It is smart in that it will fit a standard length mag and put out the same amount of gusto as it's Grandfather the H&H but it is nothing new.
Keep in mind had the bullets manufacturers made a product that would hold together better 100 years ago the 375 Ruger would also be running competition to the metric 9,3 Brenneke which other than quite small differences for case dimensions and 9 thou of bullet dia. they both boast very similar bullet weights and the same velocities. It is only because of lack of good bullets for high velocity back in the day that the Brenneke is a rare bird today. IMO, a real shame.
The German folk of RSA needed a round for the farmers to keep their livestock walking. The British had the H&H but it was an expensive gun to buy, not to mention feed. When Otto Bock came up with his 9,3x62 to fit a standard length action it made it affordable for the average farmer to take care of their spread with near the same power as the H&H in a much smaller package.
While the Ruger is a great idea, I wish some of the manufacturers would consider giving some of the old school cartridges another kick at the cat which met their demise early not because they sucked, but because they were too far ahead of their time and the components couldn't take the toll.
Hopefully my whiz bang BIL will be getting a 375 Ruger shortly, same as Gatehouse's and we can see what the "new" rage is all about. Rest assured he will be harrased to no end for buying a Century old idea. LOL He will hate the fact it is not a cutting edge idea.
