i am not very educated when it comes to ammo grain and performance. my understanding is you want a light fast bullet because it can carry more power at point of impact. so if i am looking at something for my house where i dont want alot of penetraion i should go with a heavy grain bullet. i have a G29 and for now until i get something else it is my home defense , personal defense and woods defense. my plan is to get extra mags and load em for what i need. for the woods underwood 220 hardcast. for home i was thinking 200 xtp jhp from underwood. and for personal defense i have no clue. is my train of thought correct on my choice? a 200 grain hollow point will not penetrate as much as a 165 or 180 grain hollow point out of my G29?

I'll let others who know more give more detailed answers. But the 200 xtp is a deep penetrator, it would not be best for home defense. The 155 or 165 Gold Dot from underwood would be a better idea, for home and self defense.....keep in mind a 10mm is going to put a hole through many pieces of drywall, so "over penetration" is a relative term.....

Correct...

A 200 gr 10mm is a hunting round as far as I'm concerned..

I wouldn't consider anything heavier than 180 gr for 2 legged personal defense and personally I prefer 155.


Also OP your thinking is backwards.. The heavier the bullet the deeper penetration is to be expected.

RYT 2Ber is right the heavier bullet will penetrate deeper and also a hardcast or jacketed bullet will penetrate further than a hollow point.

As far as what you want to carry, well there are a lot of differing opinions. imo the 10MM was if not created for then initially adopted by the FBI because of its good penetration. Shots have to make it into the boiler room to incapacitate quickly and BGs don't stand there like B-27 targets. After a 3 day force on force class I experienced time and again that shots were frequently on shoulders, arms and hands. imo a round that has the power to penetrate through limbs and oblique shots and continue into the boiler room is a better round for stopping someone who is trying to kill me.

Excellent post. Certainly one of the most rational and reasoned comments I've ever heard for having a 10mm for self defense.

To the OP, I would look at 135gr. bullets for home defense if over-penetration is a major concern. Just be aware that even a 135gr max load, like Underwood's, will penetrate a lot of drywall.
