I had no problem getting the pressure infro from RST, Polywad, Fiocchi, Kent, Gamebore, or the Bismuth folks. Federal responded but was vague "It generally runs between 9000-10,500 psi" Remington, Eley, and Winchester never responded to my requests, and I intend to purchase shells from those that did.
Rev,
Given all the cautions about American ammo mfrs ammo that "must be assumed to be maximum SAAMI pressure because lots of powder drive pressure all over the place and only velocity is maintained", and the confusion with conversion from one system (LUP/psi), the Armbrust finding of a error or misunderstanding, and the fact that some of these mfrs don't publish pressure data but 'responded' with data, and lastly the small but precious fingers and eyes that you have grown attached to, ....wouldn't it be prudent to get independent pressure data, rather than trust an email?
Over the years, the reloaders on this bbs, for various age guns, have exercised conservatism in selecting loads by dropping pressures below what they believed the subject gun was proofed/built to handle. For an older gun, I think its equally wise to do the same with factory loads, especially given the confusion over conversions between LUP/piezio psi.
Arbrust's services or a Pressure Trace will look very cheap after a serious problem.
Just my thoughts on all the discussion in this very informative thread.
