Recently our ballistician had some extra time in his schedule, and asked what he should work on next. We said, "Just for the heck of it, see how many times you can fire our .308s before you experience failure." So that's what he set out to do.

You are at the bench with the riser of your custom .338 Lapua stock against your cheek, and the butt is comfortably adjusted in your shoulder pocket. You give your breathing and heartrate a quick acknowledgment. You focus the crosshairs as you blur out your distant target.

Recently one of our employees was at the range and other shooters began to gather around his bench. Of course he presumed it was because of his prowess as a marksman. But instead of asking for his autograph or his expert advice, they asked him, "Where did you get that box?!"

For those of you who aren't familiar, there is an annual extreme long distance shooting competition called King of 2 miles (KO2M). This year was the third year for the event. It was held in Raton, NM at the NRA's Whittington Center on Tuesday, Wednesday and Thursday, the 27th, 28th and 29th of June.

Do you think neck tension on brass rifle casings increases or decreases with continued firings from the same casing? At Peterson Cartridge, many of our customers are long-distance, competition shooters who reload and re-shoot our casings over and over again.

Recently a shooter sent us their fired Peterson Cartridge .260 Remington casings to make us aware of an issue that they were having with the brass. The casings had chunks missing out of the heads. This had us concerned that the case-heads were splitting, cracking, or had some other unknown issue.

The main variables that cause differences in weight from case to case are as follows: Material removed when cutting in the extraction groove. External head thickness. Head diameter. Sectional density of the webbing (the base of the casing)

A change in internal volume will change the performance of your load, and potentially your results at the target. The internal volume of Winchester casings is different than Hornady, which is different from Lapua, which is different than Norma, which is different from ours.

At the 2017 SHOT Show a customer came to Peterson and expressed interest in a .300 Norma case that could hold substantially higher pressures than existing casings in that caliber. So that is what the development team at Peterson set out to achieve. And they did it.

Regarding the Peterson .308 family of casings, in large-rifle-primer size, your primer pockets seem tighter than others?

Chamfering the mouths of casings, prior to loading them with a bullet, has been a topic of debate in the reloading community since reloading became popular with private consumers. Does it make a difference in accuracy or consistency of bullet seating depth? Does it make a difference in how accurate

When we set out to develop the tooling to manufacture brass rifle casings in the two popular CheyTac® calibers (.408 CHEYTAC and .375 CHEYTAC) we set a number of goals for ourselves. We had heard all the complaints about the existing casings on the market and knew we had to resolve each

The annual King of 2 Miles (Ko2M) competition was a success again this year, and once again Peterson Cartridge figured prominently at it. This was the fifth year for the event, continuously held in Raton, NM, at the NRAs Whittington Center.

So, Peterson went back to work, designed new tooling and ran it again. Now the dimensions of Peterson's .300 Norma and .338 Norma casings mirror those made by Norma.
