Did finally get some velocity data after trying the mandrel die and I DID definitely see an improvement in SD. Went from 15 to 9 SD for a 4 shot string. The 5th shot blew it out to 13 but Im hoping thats just variance from the Chargemaster or since that batch if brass has been resized with the ball twice before using the mandrel for the last 2 loadings. .308 Lapua brass.
It’s actually .007”. A .30 cal projectile mics at .3091”.
It sounds as though he goes ‘till he likes what he sees.
If my resized and mandrel-ed cases measure .302, does that mean I have .006 neck tension? Sorry if thats a dumb question but Id rather be correct than assume.
Another great Podcast guys. I can't say how much I appreciate what you're doing for the sport. Look forward to something in the yoga department. Keep up the good work.
So when your chasing the lands and working your way back what do you use as your stopping point? For instance, do you keep going back .030, .060, .090 till you get to the book listed COAL or do you go further?
If you are using a temp stable powder are there bracketed temperature zones? Does a 20-27 degree day all shoot the same? I guess what I am asking is how much of a temp change do you have to worry about a change in your ballistics? Is there such thing as a temperature node?
Its good to hear a reloading perspective from a practical rifle shooter, so much info comes from a bench rest frame of reference. I have wasted sooooo much time concentrating on the minutia of loading unnecessarily for my purposes.
I'm glad someone on Scott's level said these things about loading. I posted a thread on Sniper's Hide titled "Dirty Loads" and it received no fanfare, it was a rundown on my abbreviated method of getting a load figured out so I can just go shoot. I appreciate hearing new ideas, good stuff and keep it coming!
Thank you guys for doing this, I myself needed someone to set the record straight on the process. I tried to learn from the Internet when I first started reloading and it generated so much frustration that the press almost went straight to the garbage. Haven't touched it in 2 years but after this I'm actually looking forward to load development. Thank you.
Really intresting podcast. One question, what charge weight is he looking at for a start when checking for seating depth? Or did I miss that part in the podcast?
