I need to try some of that (CCI SV).
I don't seem to see it for sale at the local stores. But if I ever do, I'll have to pick some up to see for myself. A lot of people on this forum do seem to like it.
But it's a "standard velocity" round, so I'm sure it's subsonic and as such, it's probably intended for target shooting, and thus, it's probably made with appropriate care and QC. From what I've seen just checking prices for it on the internet, it looks like it'll cost about double what the CCI Blazer or Federal Champion costs.
But that's really the difference. The Blazers and Champions seem to be "high velocity" rounds aimed at plinking and maybe some hunting, so naturally they're cheaper and I wouldn't expect them to be as accurate or consistent as the CCI SV which is something of a "premium" target load in their lineup.
I'd like to try some under conditions where I'd be able to really appreciate the differences. Maybe sometime this summer I'll do that.
