Hornady Introduces Yet Another New 300 Magnum Cartridge

More info is coming out on the 300PRC. Factory ammo will be seated to 3.685" OAL with the 212ELDX & 225ELDM

I redid the Quickload prediction with a 180gr Nosler Accubond seated to 3.54" OAL (.308" of bullet shank seated into the case)

Code: 
Cartridge          : .300 PRC
Bullet             : .308, 180, Nosler AccuBond 54825
Useable Case Capaci: 92.530 grain H2O = 6.008 cm³
Cartridge O.A.L. L6: 3.541 inch = 89.94 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 62000 psi, or 427 MPa
or a maximum loading ratio or filling of 103 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.

Hornady isn't messing around with this chambering

$65 die set
$140 match die set
$79 for 50ct brass
$68 for 20rnds of either 212gr Precision Hunter or 225gr Match ammo

Exact same prices as 300 Win Mag
 
Who the hell needs it though? Really?

From the article in the first post.

"I engaged steel targets out to 1,100 yards and was able to make hits. More of a “fun shoot” than an intense evaluation, actual data collection was not possible."

I'd like to know how many hits he made due to this specific cartridge design than any of the other 300 magnums.

Since it’s based on the .375 Ruger case, it shouldn’t d be too hard to imagine the ballistics if you take a look at the .375 and .416 Ruger.
 
Sounds like the problem of running .300 Winchester cartridges loaded with long bullets through a standard length magazine could be solved by using a magnum length magazine, but since Hornady is in the cartridge making business rather than the rifle building business, they chose to market a shorter, fatter, cartridge with more case capacity than the .300 WSM for people who exclusively shoot factory ammo. I could be wrong, but it seems like it would be a small number of shooters, who would specifically chose magazine fed, heavy, extended range, factory ammo over equivalent handloads. Everything else the guys in the video talk about is smoke and mirrors, since good accuracy is handily achieved with the .300 Winchester handloads, which if what they say was true, would not be possible. So, how much would 1000 rounds of factory .300 PCR ammo cost be, compared to 1000 rounds of .300 Winchester handloads? I expect I'll stick with my .300 Winchester, but who know what the future will bring.

Awesome thanks for the info Mark, the more I read up on this cartridge the more I like it, I was reading the owner of Bartlein Barrels is shooting this cartridge and can’t say enough good about it.
