    I was recently at Bass Pro Shop the other day and purchased some ammo for my 30-06. I bought the Hornady Custom 165gr SST. However, the Hornady Superformance also had 165gr SST. The only difference I could see was the box and the price. What is the difference since both have the same grain, SST rating, and also the same polymer tip?

    You can get SST's in both custom and superperformance (replaced Hornady's light magnum product).

    The superformance is about 200 fps faster than custom. I shoot the superperformance 139 gr SST's in my 280. I shoot custom 150 gr SST's in my 308.

    When I changed from standard ammo to superperformance in my 280, the s.p. was about 4 inches higher at 100 yards that standard ammo.

    There is more than just a price difference between custom and superperformance.

    so would you say that it allows for a flatter trajectory therefore making your firearm more accurate over varying distances?

    Also, I have heard that the superformance is possibly hand loaded with a more premium powder. Then again, you have to be careful with what you read.

    Flatter, yes. More accurate, not necessarily. The drop at say 300 yards should be less, but the grouping may not change significantly.

    Also, since kinetic energy equals mass x velocity squared, the s.p. load packs more energy.

    If the custom round has the same grain and same design how is superformance faster? Please pardon my ignorance and my persistence.

    Hornaday has developed some new propellants to yield more velocity out of a given load while not exceeding SAAMI pressure standards. Pretty cool stuff. They are now marketing the bulk propellants for handloaders.

    I'm afraid I am really ignorant as I don't know what SAAMI pressure standards are. In the military SAMI stood for Small Arms Marksmanship Instructor. I can only assume that the SAAMI pressure standards to which you refer has something to do with the grain of the powder or propellant. However, when you assume, we all know what happens :). Is there a link, article or book that could help me better understand the lingo? Thanks

    Sporting Arms and Ammunition Manufacturers Institute.

    The cooperative (Non Governmental) organization run by the gun and ammo makers that establishes specifications for cartridge dimensions and pressures. Because of them 7mm Remington Magnum ammunition will fit and shoot properly in any such chambered rifle even Winchester, Browning and Savage.

    After reading the link that Gatoragn sent me, I have a better understanding of SAAMI pressure standards. However, after reading the information on the Hornaday website, I have another question: Is the 150gr 30-06 SST faster than the 165gr 30-06 SST simply because of F=ma? In other words, you get a better velocity with the 150gr SST but it will hit with less force than a 165gr SST? So wouldn't the difference be negligible since the 150gr SST is approx. 70fps faster than the 165gr SST?

    The 150 is a little faster because it is a little lighter. On say white-tailed deer, the 165 would cause a lttle more loss of meat, due to higher mass, but either 150 or 165 will get the job done. If shooting an elk, the heavier bullet may be better.
