I was just wondering what is the difference between the Hornady 75 GR BTHP Match ammo and the 75 GR BTHP TAP ammo. Does the MAtch ammo expand upon impact like the TAP, or is the Match amm strictly for target shooting? I currently shoot the 5.56 TAP version in my 24" 1x8 twist Varmint Bull barrel. Thanks for all your help.

The actual bullet is the same, the only difference is that the TAP is loaded to higher velocities. The bullet does NOT expand, but rather fragments. Not by design, as it was designed to be a paper puncher only. It's just that the thin jacket and long ogive are perfect for nice fragmentation. The "hollow point" design does nothing for expansion.

Thanks, but does the match ammo make a good self defense or law enforcement round? Or is it strictly for taget shooting?

The match ammo is .223 pressure only and has no cannelure to prevent bullet setback in semi autos. If you used it from a bolt gun it would have the same terminal effects because it was the same bullet one with and one without cannelure, with a semi auto its the same with a very tiny % greater chance of bullet set back with the non cannelured version.

The match load makes an excellent anti-personnel round. Although I like the idea of a cannelure, I have never had any issues running all the OTM rounds through my AR.

Where can one find the best prices on the Match and TAP rounds?

Just for clarification, these rounds would experience great accuracy in a 1/7 and 1/9 twist rate in 16 or 20 inch barrels?

Thanks.

Not necessarily so.

Doesnt the cannelure help the round to fragment as it yaws?

To TennesseeRat: If you are in Law Enforcement you can get these rounds directly from Hornady for about $10 a box. Or you can get them from Natchez.com for abou$11 or $15 per box. As far as twist, the 1X8 twist is the most accurate that I have used, but the 1X9, 1X8, or 1X7 should be good. If you plan on using higher than 77 grain you definitely need a 1X8 or 1X7 twist.

No it does not aid fragmentation. What is the "not neccessarily so" part reffering to?

IIRC the ammo orcale makes reference to the fact that the cannelure aids in fragmentation and rounds without it dont fragment as well.

The Oracle is talking about the cannelure effect in M193 or M855 rounds, NOT the OTM, which have a completely different construction. In the military rounds the bullet tends to break around the cannelure, as it is its weakest point, but with the OTM bullets the entire bullet is fragile, due to the very thin jacket.

.

Buy Black Hills 75gr OTM Blue Box. Same Hornady Bullet (with the cannalure), low flash powder, and they run $18 for 50 rounds. The last time I bought 75gr .223 TAP it was $16 for 20 rounds...

Ditto. I plan on buying a box of it for the home defense mags.

You know, those two mags you know work 100%.
