So the ones I'd be interested in would be the 110's, but those are $0.76 each vs the $0.35 each I pay for DTAC's or Hybrids. For the PRS game it just doesn't make sense for me. BC is super close to what the DTAC's run, so you're getting maybe 50 fps speed increase and/or a bit less recoil? Not much difference than the Sierra 110's ballistics.
If you're interested in shooting super small groups you can go with boutique benchrest bullets like Barts, Vapor trails, etc. Even those are less expensive.
Gets a bit more interesting when you talk about lower volume, longer range shooting. That 30 cal bullet is pretty compelling for an ELR option.
