	Premod, I appreciate your suggestion. This is the knowledge I love gleaning from this group. In studying the group over dinner, I too noticed that yaw. That load starts out at 1288fps. I have not crunched the numbers yet to see if is nearing sub-sonic at 200.

	According to the JBM calculator, I have dropped well below sonic at 200. It is showing 956fps.

	The early tip ups were chambered (rarely) for the .44-65 and .44-50. These were to make a centerfire version of the .44 RF long and .44 RF Extra long. The .44-65 is close to a .45-70. A couple of experimental were made with a reinforced action in .45-2 4/10" Sharps. The .38-55 was a common chambering. These were used with back powder and the tip up was discontinued in 1900 about the time shooters started using smokeless. Most of the early target shooters like the .38 caliber but slowly gravitated to smaller cartridges like the .32-35 and .32-40. Of interest is that the .32-35 Maynard is different than the .32-35 Stevens.

	One of the projects on my list of things likely to never be started is to build a tip-up frame from modern steel and test it to failure. Not something I'd likely get away with doing at an ordinary 'range', but I know some people ... Same goes for a Ballard. I'd guess the 'new' ones were tested at some point, but probably no way they'd ever release any of that data.

	Two Tip-Ups that I have owned and made new pivot pins for, were near failure. One pin broke and exposed a large grain structure that was very crystalized. I intentionally broke the other after removal and it easily snapped with crystalized grain as well. Pretty sure I posted pics on this forum a couple years ago. I made new pins from AN aircraft bolts and line-reamed the hinge hole of both the barrel and frame oversize. New pins were fitted very tightly on the frame and a very snug slip on the barrel. I have seen a couple older references that the Tip-Up frames were cast steel. If anyone had a junk action it would be very easy to do a spark test of the material.

	The supply of tip up frames was from the Malleable Iron Co. and for that matter they supplied frames for the 44 actions. The 44 1/2 frames were forged.

	SBoomer if you think the bullet mould that I made you is a bit to long don't hesitate to take some off the top of the mould to shorten the bullets length.

	I'm still thinking about a rebore of my gun but I will have it marked "38-55 black powder only" Theoretically, that would relieve you of future liability, but there's always the chance that some future owner will "know better". In any case, you might well consider fitting a larger, tighter-fitting hinge pin made from a tough grade of steel. A shooter I know also machined an enlarged, widened, and knurled head to his new hinge pin to improve his rifle being a "take-down". Bill Lawrence
