The Parker Ballistic Extreme competes with the SW. The hydrocon competes with the Barnes Origonal and other Pointed Soft Point bullets. The Traditional have a hollow point. Are they as accurate, I think that would depend on the gun. Some traditional guns shoot them well, as for high charged inlines, I think you would be better off with the Ballistic Extreme or the Hydra Conn. All the Parker bullets are expensive, you can use Remington PT whatver and Traditions T Shock Polymer Tip and they are the same bullet and sabot that Parker sells for over $1 each.
In fact here is the link to the Bullet I used last yaer in my Savage:

I shot 8 deer with them last year. I like them OK, but they fragmented on 1 doe, so I didn't shoot them this year, went to a stronger Barnes Origonal 300g.
Shot this buck with them at about 50 or 60 yards, DRT

took like 1 step and the deer was running, so it does put em down fast. I like that about them. Excellent expansion.
