Looking at the Geltesting Hornady did useing there Barrier 62gr bullet
In 223rem pressure & Nato pressure

Is the larger cavity worth it with loss of penetration?

At what distance does the 62 gr projectile launched at a MV of 2910 f/s slow to 2740 f/s? What are your potential engagement distances?

Also, there are better loads available…unless you get this for free, consider picking something else if appropriate for your applications…

Thanks for fast reply Doc

The hornady catalog says 30 feet distance

What Im wondering ??

with 5.56 pressure loads do Soft Points travel less distance?
Compared to 223rem pressure loads with same SP bullet

The above seems to tell me this? But Im not a pro like yourself :slight_smile:

BTW
Doc I went with the Fusion 62gr

I order 5 boxes.:slight_smile: (I wanted TBBC 62 but cant find any)

Thanks again for the help I follow your advice
