If worried on power load with federal hydrashock 10 mm has like 420 lb energy I bought a box one time and was mad when I read balistic on them. I wanted power not a 40 smith

There pistols are junk period but there rifles ain't bad owning one is like having a pinto wagon with a 350 kinda nice but you don't want anyone to know it lol

I never tried any other barrels out of my 29 it was so accurate with the stock I didn't fool with it

Well I'll be happy to add my I put on them. When I wrote this it was as an aspect of just the 10mm round as a self defense round in the aspect of law enforcement of 2 legged varmints lol. You are thinking wrong in an aspect as the 223/5.56 does not overpenetrate unless it is stoked with a total metal jacket that round with an interesting round as with fragmenting type of fast expansion rounds for example the ballistic tip. I have seen these do exactly what I call a perfect stopping round it goes in does terminal damage and stops just prior to exit of the body. While there is no perfect round or caliber I believe the more a dept can increase officer safety while minimize danger to the public the better we are. We carried 223 rifles and I carried a 308 bolt rifle for prescicion. Every officer did have a mag of fmj ammo for in cases of barriers but they were not kept in the rifles we carried 55 gr hornady balistic tips. In the testing I have done where we hit a median of similar to human size and density most of the times all the energy was spent and did little to no damage on exit with that round while the same could not be said for the 308 or fmj 223 rounds.

There has been great strides in ammunition manufacturing and design not only in the last 20 years but especially in the last 5 years. You look what technology has done for example the 38spl 50 years ago a 158 grain lead round nose to today 100 gr high energy snub ammo made for short barrels. This goes back to what I was saying about the 10mm in the earlier post a lot of the rounds especially the buffalo bore and double tap are more designed as a hunting or a "bear" load where u are trying to stop a 500-700 plus pound animal. While these loads are great for what they are designed for and no doubt would stop a human the overpenetration would be a factor. The idea is to transfer all the energy into your target so when the bullet leaves your target it's taking energy with it. The perfect round dumps all its energy inside its target and stops 1/4 inch before it exits so to speak.

While I'm not arguing statistic and actual hit rates. Police are to far spread and training budgets sucks I know I was blessed as I was always able to get ammo for our officers to train with as we were a smaller dept (16 officers) but I got a lot of it donated and another thing the type of training is not real life anyone can stand there and punch holes but when the crap hits the fan can u hit your target?  I set up drills with smoke blanks going off running and cover to try to emphasize the real world gun fight. A big problem is the training is a joke for shooting as I have seen officers pass with 80% and that minimum and with no stress so that is not that great that means basically 10 rounds could completely miss the target if all rest was centered.

I took my shooting very seriously and still do I pratice every week. I hold a retired commission and still carry a badge. I know what you are saying but if you can do something to lower the dance of an issue why not do it. There is a change from the shotgun to,rifles. How many revolvers do you see carried? Times change training is changing for example our state police course is such a joke for qualifications I shoot it perfect last time I shot it. Times are changing training is not the same as it use to be accuracy is being replaced by spray and pray.

All I'm saying is if there is a way to reduce a chance or stop a problem before it happens do it. It's far better off to have it fixed before a problem is created!!!!

Well a topic I'm versed in as I'm a retired disabled police officer!!!! I was also the head weapons and ammunition guru in the dept also so anyways here's my 2 cents. No on underwood no on buffalo bore the power level is way to high and with over penetration I don't like them for self defense against 2 legged critters. Now with that said I don't think a 40 smith load is acceptable either as I despise the 40 S&W. Now I do carry a glock 29 now that I'm retired and have nothing but praise for the sig v crown 180 grain I also like the old win silver tip. Both of these are modest to a point but are hotter that the 40. The 10mm is my favorite round but you can get to much sugar for a nickel in cases if you are not careful and striking a innocent bystander is NOT ACCEPTABLE! So you that's why I like the sig ammo
