458 SOCOM - 300 Grain JHP - PCI Ammo

20 Rounds

With these new, budget-priced loads from Precision Cartridge Inc. (PCI), you can take down hogs and deer with ease. As a full-fledged .458 SOCOM round, this cartridge profile features a heavy 300-grain, jacketed hollowpoint (JHP) projectile. It provides manageable recoil while ensuring deep penetration into the target.

Upon impact, the JHP bullet is designed to expand in a mushroom-like fashion. This explosive transformation creates a more effective wound cavity and slows the projectile so that it transfers its momentum to the threat’s vital organs instead of passing through the body. With 20 rounds per box, you’ll have plenty of ammunition for your next hunting trip or to keep on hand for home defense.

I am a reloading enthusiast and I have encountered a problem that I need help with. I constructed a Tromix 458 SOCOM upper and purchased Black Butterfly ammunition. After a year of reloading, I have acquired all the necessary components to reload my ammunition, including Starline brass, Berrys 350gr bullets, SBR Socom powder, and Winchester primers. I also obtained a Tromix case gauge. The problem I’m experiencing is that my rounds, including the dummy round, fit perfectly into the case gauge and can be removed with ease. However, when I attempt to chamber one of my reloaded rounds, it becomes stuck and requires me to forcefully eject it by hitting the stock of the rifle on the ground. The Black Butterfly ammo chambers and ejects without any difficulty. I am using Redding dies and an RCBS Rockchucker press.

Retrieve your calipers and commence measuring the different diameters and lengths of your reloaded rounds. Then, compare these measurements to those of the factory rounds.

Exactly. The solution to your problem can be found by simply taking the time to measure and compare your reloaded rounds to the factory rounds.

Recently switched to shooting 458 socom from PCI and I have to say, it’s been a game-changer for me. The recoil is surprisingly manageable, and the accuracy is phenomenal. I’m hitting targets at distances I never thought possible before.

I’ve been shooting for years, and I have to say, 458 socom is one of the most enjoyable rounds I’ve ever used. The recoil is just enough to make it feel powerful without being overwhelming, and the accuracy is consistent and reliable. It’s become my go-to round for range days.
