Today I was thinking about new cartridges that aren't really so new, in that their ballistics are similar to much older European sporting rounds. - Like the 6.5 Creedmoor and the 260 Remington in the light of the much older 6.5x55 Swede and 6.5x57 Mauser.
Digging around a bit, I discovered that the 6.5 Grendel is very close to being a ballistic twin to the venerable 6.5x54 Mannlicher, once one of the most popular sporting cartridges on the continent. Kilimanjaro Bell preferred this cartridge for medium game in Africa, but parted ways with it when the ammunition available to him at the time turned out to be unreliable. It is said that he used long, heavy 160 grain solids to dispatch more than a few elephants, something that nobody would recommend today, assuming that it was legal to do so.
Most 6.5 Grendel rounds are shot through AR-15s today, generally limiting the length and weight of bullets to 129 grain or less. In a bolt action gun, this limitation does not necessarily apply, as long as the magazine and throat are generous enough.
Here are some velocities I found listed around the web. The similarities strike me as being greater than the differences.
85grn 2327 2780
100 grn 2788 2500-2750
120 grn 2400-2600 2300-2520
140 grn 2250-2330 ?
I have heard the 6.5x54 M-S described as the European equivalent of the 30-30 Winchester in the US. - It is traditionally used in light, handy firearms for deer and pigs, usually with open sights. This 16.5 inch barreled M-S in 6.5x54 sporterized from a Greek military rifle is a good example:
Reading about this has me looking forward to the Howa 1500 Mini action in 6.5 Grendel even more than I already had. - Especially as rumor has it that Boyds will be supplying aftermarket stocks for the mini Howa.
It may soon be possible to put together a modern version of the elegant, lightweight carbine pictured above, that will perform almost exactly the same. I can tell you from personal experience that the MS carbine pictured is a joy to carry and shoot.
We can expect the same from a Mini-Howa in 6.5 Grendel.
