One of the interesting things about military rounds developed in the late 19th Century and the early 20th Century is just how adaptable they are to various types of shooting and hunting. This has certainly proven true of the .30/06. the 7X57, and the various 6.5s. After Bell's successful exploits in the commercial ivory trade with the 6.5X54, the usefulness of 6.5 cartridges on big game should never be in doubt, particularly with the improved bullets we have today. Given a suitable bullet, there is no reason why a 6.5X55 shouldn't be as versatile as a .30/06, after all, its the handloader who determines the versatility of his rifle.
But once I was exposed to a quality rifle chambered for the .30/06 it quickly become my favorite, but that almost didn't happen. Like many, when I was starting out, I tried to get by with a milsurp 98 of questionable lineage, perhaps it was an ex-Columbian service rifle, but despite its weight, it kicked like a mule, wouldn't group into 3", and the steel butt plate did nothing to mitigate my discomfort. When I got my hands on an affordable 6.5X55 Husqvarna M-38, it was like a gift from the gods. It was more accurate than the '06, shot just as flat, and the recoil and blast were not just manageable, they were gentle. But sometimes when I get an idea in my head, I just can't let it go, and I was determined to master the .30/06, believing that the acquisition of a good sporter is all that stood between be and becoming a great hunter and marksman. After all, the guys in the magazines all used M-70s, or Weatherbys, (or Dubials or Mashburns, or Champlins) and they were no tougher than I was at 19.
Before long I had a M-700 Remington in .30/06; the M-70 had by then fallen from favor at my favorite gun shop, so the Remington was the rifle to own. With a combination of a caseful of H-4831 under a 165 gr Hornady SPBT, and topped with the ubiquitous 3-9X Bushnell in Weaver mounts, I could do no wrong. It boomed pleasingly and shot well. One day a fellow shooting at the next bench complained about my muzzle blast . . . he was shooting a MK-V .300 Weatherby, and between the blast of my rifle upsetting his nerves, and my groups upsetting his self confidence, he wasn't having a particularly good day, but I never looked at the .300 magnum the same again after that. The Remington shot MOA out to a quarter mile without much input from me, and I seldom had the opportunity or inclination to take it farther. From there on out, the .30/06 was my cartridge.
Had I in fact found a sporter of similar quality in 6.5X55, say a commercial Husqvarna 1600, or perhaps a SAKO, I may have forever shunned the '06. The fact of the matter is, that the 6.5 is a better choice as an all around cartridge for those less recoil tolerant than myself, and a little less thick headed. I wanted the .30/06 to be my cartridge, and I persevered until it was.
