I think developing this load would get slightly better accuracy but it is really more for entertainment. Remember the sabot also leaves the barrel at the same velocity, a couple of them beat the crap out of my chrony.

I have hit three sage rats with these rounds and pieces flew everywhere. IMR3031 was the most accurate at 4700 fps and AA2230 was the fastest at just over 5000 fps for a very hot load. I used a 55 gr V-max because it's flat base seated well in the sabot. The accuracy was poor (3' to 6' groups at 100 yards) but the velocity was awesome. 22 caliber sabots from EA Brown and loaded them in a 300 Winchester Magnum. This info comes directly from Cartridges of the World eighth edition, 1997, by McPherson, editing and adding to the work of Barnes. It may or may not be safe to forge on and try to force the available components to deliver what they really can't do.Ĭombine this with the fact that even the specially developed factory cartridges never really did deliver accuracy that should have appealed to their most likely market, varmint shooters, and you have a cartridge which is basically an answer in search of a question. They had to develop a special primer with a reduced charge, and neither this primer, nor any like it, have ever been made commecially available to handloaders.Īny efforts to duplicate such performance are doomed from the start. The coefficient of friction that the sabot provided was inadequate to contain the ignition pressure, and the charges would not ignite properly or consistently. The conventional bullets would hold up, but only the harder bullets would hold the accuracy standard they wanted.Īdditionally, they discovered that conventional primers were too powerful. You would probably have to use some sort of Barnes-solid-like bullet to duplicate the required hardness. Remington determined that the bullet core hardeness required was much harder than readily available commercial bullets. The bullet may appear conventional, but it is not. This propellent has never been made commercially available to handloaders, and no commercial propellent has both the burn rate and density required to duplicate its performance. 30-'06 case to contain the charge required to reach 4000fps. They had to use all of the case capacity of the. When Remington developed the round, they had to contract IMR to produce a powder which had a burn rate that was similar to a pistol/shotgun powder, but also had the higher density of a rifle powder. You may not be able to duplicate the performance of the factory Accelerators, because they use several proprietary components that are uniquely developed for this application, and which are not and never have been available commercially to handloaders.
