I figure that i can answer my own question pretty much, the 30 spread across its whole family of cartridges does just about everything a fella coukd want, from the diminutive 30 Carbine and 300 Blackout as self defense rounds to the 7.82 Lazzeroni Warbird to get banjo string trajectories and drive heavy for caliber bullets to 3000+ fps it is the be all do all of the caliber world. Even 30 caliber handgun cartridges were once considered adequate for self defense. Even in Cast Bullet Benchrest the 308x1.5 is a common chambering.
But I must admit Im rather bored. Ive got other stuff and willingly play with anything new. Ive made a return to the 38-55, am playing with the 350 Legend, did a lot of shooting with a 25-06 Encore barrel till I ruined it with a double charge of 2400 (40 grains, didnt burst the barrel but it quit its tight grouping, haven't shot it in years now) ive been contemplating on 35-30, 358 Winnie, 35 Whelen. Pawn shop nearby has a couple 40-65 rolling blocks but my 38-55 can be uncomfortable with 250 grainers above 1450 (needs a shotgun butt stock) Ive even been eyeing the 8.6 Blackout
All things have limitations and writing this, I wonder if Im the problem. In any case, what are your thoughts. Ever get bored with shooting the same thing over and over and want something new? Should we call the 30 caliber the pinnacle of caliber and call it a day? Is there anything in that caliber family that hasn't been done? Where to from here
