    I have a Sig Sauer P229 and enjoy the heck out of the gun. I picked up three boxes of different ammo to run to see which one this gun shoots more accurately. For the sake of conversation let's assume they all shoot equal as far as accuracy is concerned. The next question is in regards to ballistics and particularly bullet grain/velocity. I am curious as to your thoughts on positives/negatives of the three following:

    Remington Golden Saber 165gr - HP - fps and ft/lbs not listed on box.

    CorBon 165gr - HP - 1150 fps - 485 ft/lbs

    Liberty USM40 60gr - HP - 2000 fps - 500 ft/lbs

    The USM40 is a considerably lighter bullet (60gr vs 165 gr) and significantly faster. They claim 12" penetration but I can't verify that. In a home defense weapon I want the best that I can reliably run through the gun. While on paper it looks to have the most velocity and energy but I was hoping for some more insight. Thanks a bunch.

    Rarely is less than 135gr used in defensive 40S&W ammo so I'd be leery of 60gr. (Reliability?) 155-165 is more common and I'd rather be around that range, especially for self defense.

    Hope someone has experience with it but myself, I'd pass.

    The 60 gr stuff is frangible. Designed to delivery massive energy dump on impact and then fragment. It might be useful in close quarters (inside and airplane for example) where you need to make absolutely sure it won't over penetrate, exit the target and cause harm to innocent bystanders. The downside is that it will almost certainly under penetrate. Not a good choice for a SD load IMO.

    According to ballistics101.com the Remington Golden Saber in 165 gr. is the same as the Corbon. 1150 fps and 485 ft./lbs. ME. A good round with proven law enforcement credentials. The Corbon is also a good choice.

    Stuff like this is why I believe that people pay entirely too much attention to energy numbers.
    All other BS aside: will they cycle your pistol. Every other concern is in line behind that.
    Penetration? By it's very nature, frangible ammo is going to be a bit squirrely where penetration concerned. Seems to me that heavy clothing or ANY barrier could result in completely unpredictable behavior. Just my $.02, but I'd stick with time proven designs where my well being is concerned.
    FWIW, I'm on the "bigger hunk 'o' lead" bandwagon. When I carry a .40, 180's are on board. YMMV.

    Penetration is largely a product of mass. If they are claiming 12" of penetration with a 60 gr HP at 2000 fps, I would have no hesitation in calling BS!

    There is a LOT of hype in ammunition these days. Most of it is just that, hype.

    I appreciate the feedback and it was kind of what I was thinking. Im curious if anyone has any real world experience with that particular round. They sure market it good with the shiny box and label it as military, law enforcement and civilian. Not all things that shine are gold, or however the saying goes lol
