The Speer 45 Colt (Long Colt) 300 Grain JSP bullet is a versatile handgun round built for reloaders who demand consistency and reliable terminal performance. Whether you're loading ammunition for hunting, sport shooting, or working up defensive rounds, these .451 diameter jacketed soft points deliver the quality Speer is known for. A full box of 50 gives you plenty to work with for load development or stocking your reloading bench.
Speer bullets have long been trusted by handloaders because they combine straightforward, proven designs with solid manufacturing standards. The 300-grain weight in 45 Colt strikes a practical balance—heavy enough to carry real energy downrange, but not so heavy that velocity becomes impractical in this classic cartridge. The JSP (jacketed soft point) configuration means controlled expansion on game and a design that feeds reliably through most 45 Colt firearms, from revolvers to single actions to the occasional lever gun.
If you're already set up for 45 Colt reloading, these bullets integrate easily into your routine. The .451 diameter is the standard for the cartridge, and Speer's consistent case-to-case quality means less sorting and tweaking on your progressive or single-stage press. This is straightforward component ammunition for shooters who know what they want and aren't chasing hype—just solid bullets that work.
| Brand | Speer |
| Cartridge | 45 Colt (Long Colt) |
| Bullet Weight | 300 Grains |
| Bullet Type | Jacketed Soft Point (JSP) |
| Diameter | .451 |
| Quantity | 50 Bullets |
Yes. The .451 diameter is the standard bullet size for 45 Colt (Long Colt) and will work in any firearm chambered for that cartridge, including single action revolvers, double action revolvers, and lever guns.
These are components—just the bullets. You'll need to source your own brass cases, primers, and powder, then assemble them on a reloading press. This gives you control over your loads and is typically more economical if you shoot regularly.
The 300 grain weight is a common choice for 45 Colt hunting loads. The JSP design provides controlled expansion, and this bullet weight offers a practical balance of energy and velocity in the cartridge. Consult reliable reloading manuals for load data specific to your firearm and intended use.
Each box contains 50 bullets. Determine how much ammunition you want to load, then order accordingly—for example, 2 boxes (100 bullets) makes 100 rounds of finished ammunition.
