	Just wanted thoughts on chambering a Stevens 44 1/2 in a 257 Rimmed Robert’s Would this be to much for an original Stevens ? Thanks for any input on this Dale

	I have seen .25 Krags on 44 1/2, so think you would be OK.

	I personally would choose a different action if I wanted a .257 Roberts rimmed or rimless.

	That might be a good idea as the Roberts can create 55,000 plus PSI with its standard loads. Cartridges based on 30-30 brass instead of the 7x57 brass are more reasonable with their smaller chamber diameters. I have a vintage .219 Donaldson Wasp barrel on an original 44 1/2 and I know that Harvey back in pre-pressure test days could load on the hot or hot plus sides but even he recognized he was pushing it and increased the case capacity by increasing the neck length to lessen the pressure slightly. I load for accuracy not velocity so it hasn't been a problem for me. I also have a 6mm 30-30 barrel for that action. A CPA 44 1/2 would have no problems.

	I've had several rimed higher pressure cartridge barrels on CPA's. Issue that limited all was extraction. Modern steel gas escape hole, bit thicker sides than an original Stevens, they should and do handle higher pressure cartridges than originally intended. When I went up in velocity cases were difficult to extract. My .25 Krag vs my friends 25/30 both CPA 's good example he obtained higher velocity and better accuracy with easy extraction in the smaller case. Agree with oneatatime 30/30 case better option .
