I don’t think so.
*Update* today I sent my headspace with the go gauge. After it was set I used 1 piece of scotch tape (.0015- .002) on the back of the gauge and my bolt won’t close so I’m good there. I might have turned the barrel 1/16 of a turn from where it was. Anyway new lapua small rifle brass I started today down another grain so 37.5gr of n160 with a cci 450 primer and smoked and blew out the primer on the first shot at 3058fps. I came down another 1.5gr to 36.0 those 3 rounds stamped the brass hard with an average of 2967. Still over vv max velocity while being 5 grains below their max charge and 1gr below their starting charge. I give up on n160 not worth it to me. I Loaded 3 with 39.0gr of h4350 and had no pressure of any kind 2974 avg fps.
Not 1 thing has added up other than this power is hot as piss in this rifle. No explanation
I can relate, I did not have a good experiene the first time I tried VV-165 myself
Velocity was fine , but accuracy was down the tubes with it compared to standard powders,
I am not on the VV bandwagon myself, when there are so many other powders out there
1 bad experience with a powder is more than enough for myself
Your experience is quite extraordinary to say the least and would imprint a bad memory for years to come.
---------------------------
Glad you switched powders and got it figured out,
4350 has always been a solid accurate performer.
---------------------------
Also I MUST add here, what load works for one rifle may not work for another of the same calibers
Recent experience
(2) different 260 rifles but both chambered the same by me with the same reamer
One Long Barreled faster 8 twist load was safe with 41.0 grns of AA-2700
Second rifle with a shorter slower 9 Twist Starts to show pressure signs with 39.0 Grns
and 41.0 being too hot - again seemingly contradictory to what one would think.
--------------------------
Both rifles worked up with the exact same jug of powder
But both needing to be at aleast 3 grains apart in powder load
Point being - try to take any listed load advice for a particular powder very cautiously
--------------------------
I have interestingly found some very accurate loads when starting much lower than one normally would
such as 5 grains lower then a medium power load and thought "its slow but dang is it accurate"
So that is another added possible benefit to starter lower than most would, you may find a nice low recoiling light load that just shoots extremely well.
