no i do not. but then, i'm not the guy about to blow
up his rifle.the o.p. is. i'm the guy that asked a
legitimate question and hasn't posted any critism

And I've pointed out to you that a load that's "about to blow up his rifle" isn't going to be made safe with a .2 grain charge decrease, even if it does bring it down to compliance with a published max charge. I don't recall posting any criticism myself, either. You asked questions, you got answers.

Hopefully nothing I posted came across as criticism as it was not meant as such.
Just pointing out wide variances in published data shows there is no exact max written down in a book that is the magic real max... too many variables

That's the bottom line. As handloaders, we are on our own whether we're comfortable with the idea or NOT.

I'm not answering for the original poster or anyone else but I'll answer specific to me. Freebore is one big element that controls pressure and the guns I run over published max loads are single shot guns that have bigger freebore than most folks limited to magazines can do. Now for the answer...there are two things that beat the wind, BC and speed so I shoot the highest BC bullets and push them as fast as I can and still be accurate. I'll give up speed for accuracy but I'm always going to look at the upper node first.

I don't really care what the book tells me (I do use it for starting points), I run a ladder test and find my own reamer/barrels max. When this is done it is always done in extreme heat (summer) or high humidity (rainy/misting preferred)...once I've located that for a specific reamer it will be duplicated very closely on all barrels it's used for (assuming I stick with same bore diameter).

Just an update on an old post. I backed my load down to 41.8 gr IMR 4064 (which was another accuracy node I found when doing original load work up)

I'm not getting any pressure signs now, but I'm sure I've lost substantial velocity. Either way it's accurate and gets the job done.

Old thread! What were your before and after velocities?

I wish I knew I don’t have a chrono
