Introducing the ".45 Dynamo"
A jacketed ML bullets, without limits, designed for today's High Performance Muzzleloaders.
From tip to base, this bullet has everything...
62 grains of Powder "X" produced over 3500 ft lb of Kinetic Energy at the muzzle,
800 ft lb at 600 yards and 1500 ft lb at 350 yards
Test muzzleloader: Remington 700 'Hybrid' 28" barrel
Let me start out by telling you that I am very excited to bring you our latest creation; .45 Dynamo.
We needed a bullet that would stand up to the velocities generated by the many custom smokeless ML barrels that are on the market today. Pure Lead bullets, which are all our other bullets, work great for their intended use. Blackpowder replacement powders generating velocities up to 2100 fps are where pure lead shines. Beyond that velocity the lead bullet will actually expand on the way to the target. Our barrels are capable of generating velocities of 2400 fps+ and we needed to offer our customers a bullet to match that ability. But not just any bullet.
After 24 years of making and selling millions of pure lead bullets, we knew exactly what we needed in a jacketed bullet. After a lot of soul searching we decided that the best way to get exactly what we wanted would be to just make it.
Four different machines set up; each doing a separate job. Exposed lead Tip to rebated step-base; every dimension perfect; every detail with a purpose.
Bullet diameter: .451"
- Saboted overall diameter with MMP 3 Petal sabot: .501"
- Saboted overall diameter with MMP HPH 24 sabot: .504"
- Saboted overall diameter with MMP HPH 12 sabot: .5055"
- Saboted overall diameter with MMP 'STANDARD': .507"
Note: All sabots listed above are High Pressure and suitable for Maximum charges of BH 209 and smokeless powder.
Yes, that is correct. You will find 5 different SKU in the shopping cart for the .45 Dynamo. One includes no sabots, for 'bullet to bore' application while the other 4 allow you to pick the overall size that is the perfect fit for your barrel and load combination.
An example of the benefit of having perfect sabot fit was re-enforced to us while doing our energy and accuracy testing of the .45 Dynamo. By switching up to a sabot that was only .0015" larger in diameter, we saw a velocity increase of just over 150 fps. That combination ultimately did not yield the best accuracy. For large game hunting with a 12"-15" kill zone, however, that combination would have been the ticket.
Hunting boots come in sizes to correctly fit the hunter; we thought it was time muzzleloader bullets came in sizes to correctly fit the hunter's barrel.
310 grains was selected for a couple of reasons. 310 grains shot the most accurately in our test barrels. We ran the weight gamut from 250 grains to 330 grains in our 1:20" to 1:28" twist test barrels and day in and day out, 310 was the magic number.
From an energy standpoint, the powders that we used, generated the best kinetic energy per grain of powder burned when we kept the bullets between 300 and 320 grains.
Jacket thickness: .0125"
We needed a jacket that would protect the core from extreme ML velocities while being thin enough to allow expansion of that core at extreme ranges, where the velocities will be quite low. Effective from zero to 400 yards with muzzle velocities of 1750 fps+.
Core material: pure lead
Base design: rebated .050" step
We needed to design a base to protect the critical junction of the sabot where the petals meet the base. Flat base bullets are very hard on sabots. Round cornered base bullets are difficult to repeat in production. Our rebated step base is swaged in three of the four steps and allows the bullet to be seated into the sabot without flaring the petals and protects the base/petal junction.
For 'bullet to bore' applications, the increased surface area of the rebated step base helps retain the bullet on the powder charge. We found that more powder becomes 'trapped' around the base thereby adding additional resistance to help with accidental bullet movement.
Ogive: continuous 2S
The nose portion of our bullet is a copy of our Dead Center .45 that has served us well over its 22 year existence.
Exposed lead tip diameter: .250"
Meplat diameter: .100"
Functioning muzzle velocity range: 1750fps + (no upper limit)
Effective White-tailed Deer range: 600 yards; Elk / Moose 350 yards
G1 drag coefficient: velocity dependant; .300 - .320
Intended game: White-tailed deer and larger
