NOTE: Eagle View Research Center Has Assumed All Operations For The 5mm Craig Cartridges From Certech, Effective January 2, 2004. Lowell and Ardis Kenney Will Continue To Provide 5mm Shooters With Our Renowned High Quality Service and Superior Reloading Components.
What is it?
The 5mm Craig is a wildcat cartridge, which externally is dimensionally identical to the original 5MM Remington Magnum, except for the primer pocket and flash hole. It will chamber in Remington 5MM models 591 and 592 and Thompson/Contender 5mm barrels with no alteration to the chamber. The wall thickness at the neck is the same as the original to allow 5mm bullet seating. The wall of the rest of the cartridge is thicker than the original. Velocity with our 30 grain bullet goes up to 2350 fps: original velocity of factory ammo was 2080 fps with a 38 grain bullet.
How do we do it?
We have the bolt modified by cutting the firing pin slot in the bolt head a little deeper than the original. This work is done very slowly in order to preserve the hardness of the steel. A new firing pin is fabricated from tool steel, hardened by oil quench and tempered.
What about loading components and data?
Bullets - Standard bullets are jacketed spitzer: 30 grain JHP Slick-Silver.
Loading Data
Primers Recommended
Powder Funnels - Our custom aluminum funnels work very well.
What about Safety?
We have tested several converted bolts for over several years, put hundreds of rounds through several rifles and have not experienced or had reports of any failures or other safety problems with converted bolts. According to Remington, these firearms were built to very high quality control standards. The chamber and extraction system were specially designed to safely function with the high pressures generated by this cartridge (SAAMI specification called for 37,000 psi with a maximum product average of 42,900 psi, and a maximum proof pressure of 62,000 psi). However, this is an after-market, wildcat conversion with no connection to Remington, and is not sanctioned by anyone. In short, we use it ourselves and believe it to be safe, but stress that extreme caution must be used just as you would do with any firearm or handloading product. With respect to the brass cartridges, they are machined, and are not as hard as drawn brass; it is possible to load cartridges hot enough to cause primer pocket expansion to the point of allowing gas leakage, so the recommended loading maximums must be strictly followed.
What is the Fire Lapping Set?
The Fire Lapping Set listed on the price sheet is for uniforming the rifle bore and produces a mirror finish on the inside. It consists of a series of laboratory grits in paste form (220 to 1200), with 2 steel plates. Bullets are rolled in the grit prior to loading, wiped clean, then loaded, fired through the barrel. This is easier than conventional hand-lapping, and results in improved accuracy and easier cleaning. The kit will lap 10 - 12 rifles or pistols. In rifles we lapped, accuracy was improved by 30% to 50% at 100 yards.
