As far as the 204, it never really caught on here. Still see a bunch of deuce and deuce mags mostly do too the variety of bullet weights that can be used.
Here the 223 is still the most common as we don't have to many areas anymore to shoot Pdog or sage rats mostly just yotes, which we have an abundance of and for that purpose the 223 does just fine. But if I need more, then the 22-250 and Swift more than adequately fill the void.
Yes, I've heard the plague got a lot of PD towns, and that
ranchers started getting 2d incomes from leasing.
I grew up in SW Nebraska. Back in the 60's & early 70's, the
.22-250 was the go-to PD rifle. I got tired of the wind
blowing the 55gr pills off target, soo, wanting a combination
deer/varmint rifle, got a Rem700BDL in .25-06. I connected a
lot more with the ol' Hornady 75gr HP's. However, had there
been such an aminal as a .204 Ruger back then, it may have
gone places out there.
I believe I'm just going to start out with CCI450, 24.5gr
H4198, 33gr V-max (NOT a typo), and OAL of 2.260 in Hornady
brass.
H4198 does a fine job in the .45/70 as well. Easily breaks 2,000 fps with a 350 grain bullet.
Not that this has ANYTHING to do with it in a .204 Ruger...

Funny how it turns out that powders for these little rounds
are also used in heavy calibers. I see where some are using
IMR3031 in the .204 Ruger.....I use it in my custom .45
smokeless muzzle loaders. Others such as H322, AA2015, H335,
Varget, etc., can also be used in both.
