This Grizzly .357 Magnum loading combines a full metal jacket flat point bullet with the velocity needed to get downrange performance. The 148-grain bullet weight puts this round in that sweet spot for practical revolver use, and the flat nose design feeds smoothly while maintaining straight-line penetration typical of FMJ construction.
The flat point design is where this ammunition separates itself from round nose alternatives. Instead of a rounded tip, you get a squared-off face that cuts cleaner through barriers and creates a more consistent wound profile. At 1550 fps from standard barrels, this round hits with authority without requiring exotic powder charges or magnum-level pressures. That means your revolver works the way it was meant to, feeding and extracting without hiccups round after round.
Grizzly loaded this ammunition close to maximum SAAMI pressure specifications, which means you're getting real magnum performance. Every round undergoes strict quality control during manufacturing, with the company's founder personally overseeing production. The ammunition ships in reloadable brass cases with boxer primers, non-corrosive formulation, and clean-burning powders. That last part matters if you're going to shoot it regularly without worrying about leading or fouling your barrel.
Whether you're training with a Security-Six, GP100, or another four-to-six inch revolver, this loading presents no surprises. FMJ ammunition works well for range sessions because jackets don't leave lead deposits in the barrel the way plain lead would. The 20-round box makes it easy to grab what you need for the range without tearing open a full case, and if you're reloading, saving the brass pays dividends over time.
Yes. FMJ ammunition is the standard choice for range training and target work. The 148-grain flat point feeds reliably through revolvers, and the full metal jacket design means no lead fouling in your barrel. Shoot it in any modern revolver or carbine chambered for .357 Magnum.

Yes. The ammunition ships in reloadable brass cases with boxer primers, making it a good choice if you handload. Save the brass and you can reload these cases multiple times, which helps offset ammunition costs over time.
The flat point design feeds more consistently through revolver chambers and creates straighter penetration when it hits the target. It cuts cleaner through barriers without expanding, which is why FMJ flat point ammunition is preferred for practice and general range use over round nose alternatives.
