BB,

Here are the details for the 165 grain HE TBBC

muzzle velocity - 3,000 fps vs 2,800 fps for conventional
100 yds - 2,730 fps vs 2,540 fps for conventional
200 yds - 2,470 fps vs 2,290 fps for conventional
300 yds - 2,230 fps vs 2,050 fps for conventional
400 yds - 2,000 fps vs 1,830 fps for conventional

Regarding your question on the bullet, it would depend on what grain HE you are getting... If you buy the 180 grain HE TBBC, yes it would be the same as the 180 grain traditional TBBC. I opted to go with the 165 grain HE TBBC for Moose this year because it had the same/better balistics than the 180 grain TBBC up to 200 yards which was far more than I could have even seen a moose where I was hunting.

The only thing to note, and I saw this happen personally, is not to use these HE bullets in semi-automatic rifles. My uncle tried it despite my warning and it jammed up his ejection system.

Good luck
