you might have already said this , but I'll ask again .
was this new , unfired brass ? usually new unfired brass , has a slower velocity , compared to fired brass that has been properly resized . I doubt you get 150FPS difference , but there will be a difference . I use Norma...
I have to wonder about making the barrel harder too . at what point does a hardened barrel split because it can't expand . 80KPSI will bring out the weak links , in this chain .
YES , for sure . a guy can slowly add powder and watch for pressure , and velocity . just stop at the first pressure signs . don't be blinded by the velocity you're trying to get .
glad you figured out I forgot the word NOT , in my first reply . I edited that post .
I'm not sure if it's any help , but here's what I have .
only 2 of my books showed H4350 powder . one book has a flat base bullet , the other book a boat tail bullet .
I would **" NOT"*** be concerned over 100 FPS , at the distances you would be hunting with an open sighted 30/30 . with the ammo grouping like this , I'd grab it and go hunting .
EDIT; to add a forgotten word , **"NOT"**
I wonder if a different alloy in the copper being used , could weigh 10 grains more ? If the 160's measure out to the same specs as the 150"s I'd say this is what happened . it just seems like too much R&D , plus machine set up time , to make a 160 bullet on a whim . on second thoughts ...
the problem I see with this unicorn stuff is ; these bullets will be exactly perfect in every way . they will shoot small groups , with zero load development effort . they will expand like no other bullet .they will penetrate into next week . they will be the highest velocity bullet ever...
at one time , my thoughts on V- V powder , was I couldn't buy it locally , and it was expensive powder + the hazmat ,+ shipping costs , made it to where I'm not paying that . then we got into the scarce components saga . now V-V powder is priced inline with other brands , or maybe cheaper...
@ BLKram , I'm going by memory here , so I could be off some .
I'll guess within the past 5 years , Douglas had a Death . I "THINK" his name was "Stan" . I'm not sure if he was an employee , or if he was in amongst the ownership . from what I've read ; Stan , seemed to be...
