So I had a good friend of mine ask me a question about firearms tonight that I usually would be able to answer no sweat (aside from 'smithing JD, Bear...). He owns a few hunting rifles (.22-250, .243, 300 mag) and is one of the hundreds who are unemployed, so money is tight. He just moved to an apartment (not exactly a great part of town) since he and his family couldn't afford their house anymore. He is absolutely against selling any one of his precious rifles and asked me what I would use as a HD high power rifle round. This is the part where I had absolutely no clue what to tell him. I've had my pistol for as long as I can remember, thus, never thought of using an over penetrating, super velocity rifle as a "defensive" solution. Now, being the awesome friend I am, I told him he could borrow my P99 after my 1911 comes in, which may be weeks, months, or days. My question to you is this... If all you had was a rifle, what kind of ammo would you use? Keep in mind he lives in an apartment so extreme expansion and the least penetration is key. I have researched and glasers are not available in his calibers. Thank you for your insight.
