You didn't clarify my first question to you ?

I'm still laughing that you think im putting people at risk!
For what!!Recommending a third fastener?? c'mon get serious !

Second, I concure with your statement on the weatherby but that didn't have anything to do with the statement you made prior. ! you were trying to explain another blow up scenerio citing notes on an entirely different rifle cartridge combination.
I did'nt contradict myself there ..
One can't compare cartridges loaded for and chambered in strong actions such as bolt or modern falling blocks, to those that are to be fed into SxS Double rifles.
we are talking 2 entirely different applications of powder to action types.
Regarding the brass ? I didn't cite any pressure numbers ? Ackley's book volume 1 pg 95 is a place to start maybe you'll learn something !

"The faster the better on the pressure curve" pertains to the use of the DR action and or reduced loads in large capacity cases.
Without doing the math i.e expansion ratios, bore capacities etc.. I would say the loadings in big bore nitro's are infact reduced loads in large capacity cases...sound reasonable ?
I don't have any experience with beretta arms other than with the 302 semi auto 12 ga and it's junk where handloads are concerned. IMO of course.
Hopefully the 302 that I had isn't a true measure of their engineering expertise. My opinion.

I don't claim to be an expert at anything other than at my day job, as should we all be, and I'm surely no expert at gun making but I built an excellent 500/450 3 1/4" magnum double that's both functional and finely finished (yet to be BluedBrownedblackend ) including the stock work on a quality suhl action with nothing other than a copy of A. Grey's book "The Hammerless double rifle" for reference.
I'm not trained in gun making but I've built guns ranging in "belt buckle pistols" to "full scale exact replica Muzzleloading artillery" , so I have learned a few things along the way believe it or not...
I'll get some photos up so you won't think I'm full of it!
