	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 .

	I think that the 257 Roberts would be a poor choice on an original 44 1/2 action. The 30/40 Krag is a marginal choice as it is so long and the rim diameter is large enough that loading is not easy to clear the hammer I was told when I had CPA rebarrel my rifle. The 257R is a 50,000 psi round when loaded by somebody down the line tries to make the 44 1/2 into a Ruger #1 and it has a larger case diameter than the Krag case. A 25 Krag would be a better choice but I went with a 25/35 after discussing it with Paul Schuttleworth. If you need more than a 25/35 Improved would be the ticket. However, Ned Roberts had a Neidner built 44 1/2 in 25 Krag so the best riflemen of the day had 25 Krags on the 44 1/2. My rifle sports a lightweight 28" barrel with a 1;9 twist and is a tack driver and deadly hunting rifle for mule deer and antelope. Extraction is week so the Improved version of either the Krag or the 25/35 might help. I have a Borchardt that Curt Hardcastle built for me in 30-40 Ackley Improved and it extracts perfectly. I also have a Ruger #1 in 7mm Ackley Improved for when I want to reach out and touch something! The Krag case is easy to neck down to 25 caliber. Just my 2 cents and now that they don't make pennies might not be worth much. Attached is a picture of my 25/35. Tom

	(You need to *Login* or *Register* to view media files and links) 6x51R I could see 7x57R brass being good parent brass, but 444 might lengthen enough. It did to make the 6x51R. I ended up cutting about .20 inch off the necks. On an original 44-1/2 I think I’d stick with something on a 30-30 case

	I have a Merkel K1 and in 7x57r that’s what got me thinking about the 257r but sounds like A bit much for the Stevens I have a 44-1/2 49 that I put on a barrel in 25-35 for offhand maybe a light barreled 25-35 on another action is the way to go. Thanks for the input. Dale

	Dale, my 44 1/2 25/35 has a 28" lightweight barrel and is a real pleasure to hunt with. I went with a 1:9 twist Douglas barrel and it shoots 100 gr to 120 grain bullets either cast or jacketed. I have a tapered 115 gr cast bullet that I breech seat with two plugged cases per instructions from Paul Shuttleworth, one to get the bullet started and the other to seat it completely. Tom
