	Not considering doing this. It's an idea for a story I'm writing. Thought I'd run it by you guys. Is it reasonable (that is, safe) to think about converting a beat up No. 5 roller in 7x57 into a coyote rifle with a heavy barrel in .223, set up to use military surplus ammo?

	I wouldn't. But I think DeHaas did some rebarrels to the #5 I wouldn't do either.

	I think one would have to weigh just how dangerous what could go wrong could be if anything did go wrong.

	In the last few weeks there have been two rolling blocks on Gunbroker that started out as 7x57, but one was rebarreled to .257 Roberts and the other in .260 Remington. I’m thinking neither one was a great idea……..

	I think I read somewhere that 40,000 psi pressure as an absolute maximum pressure. For a coyote rifle I'd look at the 25-35, or the rimless 25 Remington cartridges. Me; I just left mine in 7mm and load at the bottom of the recommended loads. George

	I actually saw one in .223 this last Saturday at the Kallispel gun show. I didn't pick it up, just glanced at it and saw the small hole. It was laying next to one of it's unmolested brethren. My first reaction was, "Some things are just wrong." The second thought was, "who ever shoots that thing needs to dial 911 before pulling the trigger."

	At the GS at Puyallup many years ago I saw a rolling block, an old rolling block in 6 or 6.5 that chambered a rimmed bottle necked case. It was a very old original outfit. Once in a while I still kick myself for not buying it. It's funny how many time bombs are out there that never seem to explode. Look out! Look out!!

	I saw one rebarreled to .257 Roberts by a gunsmith who I thought knew better. A customer had the thing rebarreled for his son. I'll abandon that thread in my story. It might give someone a bad idea. Thanks for the input.

	The 223 case head is a lot smaller creating less back thrust than the 7 mauser. Not saying it would or would not be safe. There are better combinations for an old rolling block.

There are better combinations for an old rolling block. The 7mm Mauser rounds of the early 1900's chambered Rolling Blocks were nowhere near the pressure of modern 7mm ammo we have today. So thrust pressure wasn't the same as today's ammo either. But even those modern smokeless Rollers in 7mm are often found with some headspace issues. Maybe from being fired with modern 7mm ammo?

	I wouldn't do it, personally. But, I'd look at the actual thrust as already mentioned. AND I wouldn't chamber it in '223'. I'd use a NATO chamber for use with surplus ball of whatever spec' and origin. And brass is 'one and done'.

	I remember back around 1960 when my father contacted PO Ackley to see about rebarreling a Model 5 to a 22-250 which was still a wildcat at the time. He said he would do it. Thank goodness my dad didn't follow up or I might be missing some fingers or an eye or two. I would go with a 219 Zipper if I was building a 22 caliber rifle. I have a #5 rebarreled to a 6mm/30-30 Improved that I load reasonably for and it had no problem taking an antelope a few years ago. I wish 25 Remington brass was more available as I really like the rimless cases in my #5 rifles as the rim can get behind the extractor and you are out of business until you tap the case out. Don't ask me how I know that! Curt Hardcastle has installed a limit screw on my 50-70 and 38-56 to eliminate that problem. Tom

That is precisely what my thoughts are for the story I'm writing. What are the differences in the two chambers? In my tale, a shepherd has a coyote problem, access to a lot of formerly military ball ammo, and no interest in or need for reloading. Brass is "one and done" but the empties are sold or traded, never discarded. The rifle needs to have a very simple & rugged 4- or 6 X scope. what brand should I mount on the rifle?
