Things tend to be cyclical. I keep wondering when the 'soft shooters' will resurge. I mean, magnums, then belted magnums, then unbelted magnums, then rather than continuing the 'bigger-badder-magnum' trend, we switch to short magnums, matching the older longer brothers, not trying to blow past them with pounds of powder. And then I look at the 338 federal, not a magnum at all, and the 17 HRM keeps on selling very well, and the 204.
I look at the lineup of centerfire rifles, with the sales of 204 and 17 HRM in my mind, and what gaps do I see? No gaps of note above the .223 and the 30-30, but plenty below, of two types.
1. Small caliber bullets that are faster than rimfire but less powder and noise than .223. I think this is one of the reasons 22 hornet has been growing in popularity again. I really think a case with about the same capacity as the hornet but not as weak at the mouth with either a 17 or 20 caliber bullet would be quite interesting. A 20 cal soft shooter that can match velocities with the .223? I think it would sell.
2. bigger bullet soft shooters. All the old 32-20s and 25-20s 32 Ideals, even the 30 carbine, they are long gone. I sometimes think that this is why the pistol caliber carbine is popping up, there is a vaccume there. We just need something with about the power of a 9mm or 45acp, but a slightly better long range bullet, (read 25-32 caliber) I wonder how the 327 federal would do in a light weight boltaction
