Weight and bulk. The Single Seven is significantly smaller and lighter than the large frame Blackhawk 30 Carbine./QUOTE]
Well, this is a valid point. However, I have my doubts about the other points. Like operating at higher pressures; that's a negative value that means a lot more decibels at the muzzle.
Mind you, I'm on the outside looking in, as I don't have any of these calibers. The only revolver I own is a 45 Colt Vaquero, which is in a completely different league. But in my perspective, I was pointing out that the 30 Carbine and the 327 Federal, are both in the shadow of the 357 magnum in terms of achieving the widespread acceptance and popularity that would result in adequate product support. That means readily available ammo at reasonable prices and readily available firearms, including rifles and carbines. How about a Marlin 1894, (with the loading gate, thank you...), in 327 Federal to go along with your revolver? Until that happens, people like me would sooner choose the 357. The 327 Federal needs more people like yourselves to create that demand before the rest of us can consider jumping in.
