Chamber cast is cheap insurance.

Bretheren: I believe I have narrowed it down to where I can fireform the correct cartridge with a small charge and a cream of wheat w/seal. Please see if my madness checks out. The bore diameter measures .250 when a proper micrometer is used. The 6.5x55 and now the 25/06 Rem. WILL NOT CHAMBER. The 250 Savage WILL CHAMBER. The .257 Roberts WILL CHAMBER, as well. Ergo... If the .257 Roberts CHAMBERS IT CANNOT BE A .250 Savage, as the .257 Roberts is TOO LARGE to chamber in a .250 Savage chamber due to the shoulder diameter being .414 on the .250 Savage and .430 on the .257 Roberts. Therefore since the bore is .25 caliber, and the chamber is too small to be a 25-06 and large enough to accommodate a .257 Roberts, by process of elimination it has to be a. 257 Roberts and even if it is a .257R ACKLEY IMPROVED, firing factory cartridges, merely fireforms them to an AI. The other three .25 caliber cartridges 25/20 and 25/35 and .25 WSSM don't enter into the equation for obvious reasons. What say you to this theory?

6 mm Remington and .257 Roberts has same parent case i.e. 7x57 so it seems that yours rifle is either .257 Roberts or .257 Roberts AI.

I had one of these...once

A fireforming load in any case you can chamber,won't build up enough pressure to hurt your rifle.Have at it.

I suggested fireforming a 6 m/m Rem case several days ago. I expect it will blow out to .257 Roberts dimensions, or some improved version thereof. Use new or annealed brass so it fills out nicely without any splits. Of course, using .257 brass for your fireform load will work too. I suggested 6 m/m because it sounded like you already had that cartridge on hand.

The .257 Roberts is a great cartridge for your wife to use, so hopefully you'll get the standardized version that is available in off-the-shelf reloading dies. Good luck.

THANKS EVERYONE! LAST QUESTION: Does everyone agree, that my Process of Elimination resulting in the .257 Roberts, being the PROBALE/LIKELY cartridge is a sound one? Jerry

yep
