MidwayUSA teamed up with Lee Precision to custom design a cast bullet that would not only function from a suppressed AR-15 in 300 AAC Blackout at subsonic velocities, but would not have problems feeding from a magazine and stabilize with the fast twist barrels. This bullet has a smaller meplat leading to a long gentle rounded tangent ogive to ensure that the bullet will feed from a magazine and be less sensitive to bullet seating depth. This bullet also has a boat-tail design to help increase the ballistic coefficient, reducing drag helping the bullet to overcome air resistance in flight. Some reloaders have even reported that they can seat gas checks on the boat-tail to help reduce leading when loading this bullet in other calibers. The tumble lube design of this mold is perfect for shooting subsonic loads out of the 300 AAC Blackout.
Lee Bullet Molds are a great choice for reloaders looking for a quality mold at an affordable price. Lee machines their mold blocks from aluminum making them rust resistant. Aluminum molds heat up and cool down faster than iron or steel molds and good bullets can usually be produced only after a few casts. In addition, aluminum blocks are one-third the weight of iron or steel mold blocks offering the bullet caster less fatigue during extended casting sessions. To ensure the best possible bullets, mold block are CNC Machined for unmatched roundness and size control. Weights given are Lee’s weights with suggested alloy; actual weight may vary due to the alloy mixture used.
Bullet Length: 1.363″
A note from Lee Precision on their bullet molds:
Lee Precision does not recommend the use of any spray type mold release products in their bullet molds. The use of such products may result in a build-up of the release product in the bullet mold cavity, reducing the diameter of the bullets cast from the treated mold. Instead, Lee Precision recommends smoking the mold with a wooden match, beeswax candle or a butane lighter as described in their provided bullet mold instructions.
