Hey,
I got a custom shop Encore barrel in 30 carbine. It's over twice the power of the 32 H&R Mag, yet still a pussycat. I loaded it up (carefully) way past the loading manuals limits and had absolutely no pressure problems. Ran out of case before I got into any pressure issues. Moreover, the Speer #1835 (110 grain) HP bullet expands perfecty at the velocities generated.
Add to that the super cheap cost of surplus ammo & brass, and I'd argue it's the better choice. Just my $.02.
