Developed by George Gardner of G.A. Precision and based off the Ruger Compact Magnum case, the 6.5 PRC was created for use in the Precision Rifle Series matches.

Introduced in 2017 as the fourth in a family of new cartridges from Nosler, the 33 Nosler features a 35-degree shoulder and a beltless design for ease of reloading.  The 33 Nosler can launch a 225-grain bullet in excess of 3,000 FPS, while using less powder than a .338 Lapua.

Peterson Cartridge makes finished casings in the popular belted magnum calibers, like .300 Win Mag. and 7mm Rem Mag. According to president Derek Peterson, “We’re now offering belted magnum basic brass for those customers who want to form it into their favorite belted caliber.”

The origins of one of the most popular cartridges designed by Roy Weatherby date to the 1940’s, when he used the existing concept of a venturi shoulder for his famous double radius shoulder magnum cartridge known as the .300 Weatherby Magnum. The .300 Weatherby Magnum has been a favorite of long-range big game hunters since its formal introduction in 1944, largely due to its velocity and muzzle energy advantages over its contemporaries.

Peterson Cartridge Co. of Pittsburgh, PA today announced the addition of 6.5-300 Weatherby to its growing family of rifle casing calibers.

We are excited to sponsor the Peterson Cartridge Challenge, PRS Pro Series match this April 17th and 18th. The match will be held at MKM Precision in Kennerdell, PA and will host 18 challenging stages that MKM Precision is well known for.

Remington hit a home run back in 1962 when they introduced their new Model 700 bolt action rifle, along with a brand-new belted magnum cartridge, the 7mm Remington Magnum. It became an instant hit with big game hunters and shooters largely due to its versatility and longer barrel life compared to Winchester’s .264 Winchester Magnum.

Introduced by Norma in 1999, the 6.5-284 Norma is a standardized version of a concept that gunsmiths and wildcat fans have been doing for years. 

Featuring a 40-degree Ackley-type shoulder and 10 percent more case capacity over the parent 6mm BR case, the 6mm Dasher has been used to set records in the 600 and 1,000-yard benchrest community, and has become a favorite among competitors in the Precision Rifle Series as well. 

Peterson Cartridge Co. of Pittsburgh, PA announced it is producing .300 Win Mag casings in two versions. Peterson makes the traditional SAAMI spec’d version that headspaces off the belt. But it also makes a version that headspaces off the shoulder. Peterson calls that version the .300 Win Mag- Long.

The .280 Ackley Improved casing will launch a 7mm, 120 gr. bullet over 3,400 fps. The .280 Ackley has a similar velocity to the 7mm Rem Mag, when using light to mid-weight bullets. It also tends to produce less recoil, and less muzzle blast.
