Why Choose Accurate MR 3100?
As experienced reloaders at Alaska Gun Shop, we’ve tested MR 3100 extensively in our own firearms and found it to be one of the most reliable powders available for medium rifle cartridges. The consistency from lot to lot is exceptional, which means you can develop a load with one container and confidently reproduce it with future purchases. The clean-burning nature reduces maintenance time while the excellent metering properties make it ideal for both beginners learning proper technique and veterans looking to streamline their reloading process.
Load Development Recommendations
Always consult current reloading manuals for specific charge weights and start at the minimum recommended loads. MR 3100 performs exceptionally well in .223 Remington with 55-69 grain bullets, .308 Winchester with 150-180 grain projectiles, and 6.5 Creedmoor with 120-140 grain bullets. For handgun applications, it works well in .357 Magnum and .44 Magnum when loaded to medium velocities. The powder’s forgiving nature makes it suitable for progressive press users while still offering the precision demanded by benchrest competitors.
