Description
IMR 4350 is an 8-pound keg of extruded rifle powder for serious handloaders. It’s built for consistent, accurate loads in medium to large rifle cartridges like the .30-06 Springfield and .270 Winchester. Since we started carrying it in mid-2024, it’s become a regular reorder item for us due to its consistent popularity with our customers who demand reliable performance.
What Makes It Stand Out
- Consistent Metering: The extruded kernel shape meters predictably through powder measures, giving you repeatable charges.
- Temperature Stability: Formulated to maintain consistent burn rates across a wide range of temperatures you’ll encounter in the field.
- Versatile Burn Rate: Its position on the burn chart makes it an excellent choice for a wide array of popular hunting and target rifle cartridges.
- Proven Track Record: IMR powders have a long history of reliable performance, trusted by generations of reloaders.
- High Load Density: Helps achieve optimal case fill for consistent ignition and pressure in larger capacity cases.

A quick note from our bench: the powder itself is perfect, but the cardboard shipping box is a bit flimsy. Handle the keg with care when you receive it.
Common Questions
Is this suitable for .308 Winchester loads?
Yes, IMR 4350 is a classic and effective powder for .308 Winchester, especially with heavier bullet weights (168-180 grain). Always consult current, published load data for your specific components.
How should I store this powder?
Keep the keg sealed in a cool, dry place away from heat sources and open flames. Consistent, moderate temperature is key to long-term stability.
Do you provide load data?
We do not. You must use a current, reputable reloading manual from publishers like Hodgdon, Lyman, or Speer. Start low and work up your loads safely.
