Modern Versatility

375 Raptor is the best short action / AR-10-length cartridge for firing both high BC, supersonic hunting and target shooting projectiles as well as heavy, accurate subsonic projectiles. Efficient powder burn in the .375 bore provides phenomenal performance from short barrels and great results when suppressed.

Our 375 Raptor builds shoot sub-MOA to sub-half-MOA, 5-round groups at 100 yards even with soft point hunting ammo such as 270 grain Speer boat tail soft points.

Supersonic and Subsonic

  • Supersonic hunting loads from 195 grains to 300+ grains. Most major bullet manufacturers have a long history of making and perfecting .375 bore projectiles for use in the .375 H&H Magnum, which was introduced in 1912. All of the best hunting bullets in the world are available in .375, and many extremely high BC, long-range projectiles are available in this caliber as well. Supersonic 375 Raptor loads are absolutely devastating on game and are fully capable of confidently taking any animal in North America (and have, from moose to Kodiak bears) and beyond (375 R has taken Cape Buffalo and other African game as well).
  • Subsonic loads from 350 to 450 grains. 400 grain projectiles will be the standard for us, with subsonic expanding hollow points already available from a couple of respected projectile manufacturers. A 400 grain subsonic 375 Raptor still has 1,000 ft-lbs of energy at 100 yards! 350 grain Sierra MatchKing loads are amazingly accurate out to hundreds of yards.

It just makes sense

  • Short barrel performance: 270 grain loads at 2,200 FPS from a 12-inch barrel! Compare that to a 185 grain .308 Winchester that does about 2,280 FPS from a 12-inch barrel. And it's the same amount of powder from the same case! The larger bore diameter allows for a quicker, more complete powder burn as well as the use of a faster propellant while maintaining the same pressure levels.
  • No voodoo: 375 Raptor is a .308 case necked up and trimmed for the .375 bullet. It requires nothing more than a barrel change, whether in a bolt action or an AR-10, to switch from .308 to 375 Raptor. Same bolt face, same magazine, same gas system, etc.

Budget Friendly Performance

  • Affordable: thanks to the huge selection of available .375 projectiles and the many decades companies have been manufacturing them, bullets start at just ~32 cents each. Reloading from .308 brass is very straightforward. Factory loaded hunting ammo runs about $1.70 per round.
  • It's stable: 1:8 twist rifling is perfectly sufficient to stabilize up to 450 grain subsonic projectiles without spinning even the lightest, fastest supersonic loads too fast. 375 Raptor's larger diameter provides more inherent stability as well as more mass in less projectile length. Abnormally fast twist rates aren't needed to stabilize subsonic 375 Raptor loads, so there is no risk of jacket separation when shooting supersonic loads.
  • It's real and it's available now.

Testimonials

I know it's not normal to write a review before trying a product yourself but I just had to. Last Tuesday I was grabbing a quick snack with my friend Lenny at my local feeder -- they typically serve corn in the evenings. Just after Lenny and I began our meal his head exploded. Now, normally I would blame the corn, but when my head didn't explode I realized this was different. Naturally I ran as fast as I could. After a few hours I went back to see what happened to Lenny. I was able to recover a large, heavy bullet stuck in a tree near where Lenny's head exploded. After a little more investigating I found a cartridge that said 375 Raptor on it. It appears that a 375 Raptor caused Lenny's head to explode. Great cartridge for the task.

The ranch I live on is managed by a nice guy named Brent. He only shoots at us pigs with Subsonic 300 Blackout. I appreciate that he gives us a sporting chance to survive. Up until recently the ranch manger and us Pigs had a sort of understanding; almost a treaty. We could eat as much of his crops as we wanted and occasionally we would let him use us for target practice. We don't really  mind subsonic 300, it's quiet and it tickles when Brent hits one of us. Well, last week Brent broke the treaty. Now everyone I know is dead except Dalton, who should have been killed first. You see, Rancher Brent switched to subsonic 375 Raptor. I am so mad I am never eating Brent's crops again. I hate you 375 Raptor.
