those do sound like they are right up my alley. I'll see if there are any available in cartridges i shoot.A buddy of mine brought some out a couple seasons back, and yes, in theory, the tip disintegrates to provide rapid expansion....... my initial thought was "oh look another ballistic tip"........yes and no....they're very violent, I would like to get them as components because I don't buy factory ammo either anymore but WOULD like to see them at my press. @LoonWulf would definitely appreciate them I think, they're right in the grenade first, maybe exit later category, not a splash wound, but definitely more explosive than what I've gotten a 95 gr nb tip to do outta the .243 so far. ...perhaps more similar to a berger.... (at least the small sample of bergers I've played with so far).
Eta this was from the .270 at 30 yds.
Off hand I can't remember who's loading brownings ammo for them.
