FAQ
What is the best 10mm ammo for bear defense?
Many woods carriers choose heavy hardcast loads such as DoubleTap 200 or 230 gr for deep penetration. Check local regulations and practice with your carry load.
Is 10mm more powerful than 40 S&W?
Yes. 10mm has a longer case and a higher SAAMI pressure limit (37,500 psi vs 35,000 psi), so it can push the same .40" bullets faster.
What grain is standard 10mm ammo?
180 gr is the most common 10mm practice weight; defensive and woods loads range from 155 to 230 gr.
