I'm a big 35 caliber fan, and I really wanted to like this cartridge when it came out. But, it just seems a little 'meh' compared to other options. If I needed a 35 caliber straight walled cartridge, I'd probably go with a 357 maximum before this. Maybe a 357 mag in a leveraction - because I like the platform, and I'm getting an extra 150-250 fps out of a carbine length barrel compared to a handgun.
And for true 35's I'd rather shoot a 35 rem, 356 win, or 358 win...
I'm guessing this cartridge will probably fade away.
