Here’s the setupâ€
Brand New Ruger M77 Hawkeye 30-06 All Weather
Bullet: 165gr Hornady SST
Powder: IMR4350
Primer: CCI BR2
Brass: Federal
Prep the brass using the following method:
Tumbled
Full Length Resized
Trimmed, cleaned primer pockets, champhered,sp?) and re-tumbled
Wiped down and blew out cases with compressor
Weighed each piece of brass and grouped
Hand Primed
Now with the brass ready I measured each charge working from the min to the max according to Hornady. My lee manual’s max was a little lighter than the Hornady manual I was using.
Tested the rounds and as I approached the Hornady max of 57grs the groups were tightening up. I never reach anything better that 1.5â€. My velocity topped out at 2800fps on the max charge rounds. Needless to say I started perusing borrowed manuals from reloader friends and I find a lot of conflicting min and max ranges more so on the max numbers. I have in my hand right now a IMR load data sheet listing 60grs max for a 165gr bullet in 30-06. This is 4grs more than I loaded as my max.
Who should I use as a max?
Why are there such varying data out there?
Anyone with experience using my components listed above?
PS: Absolutly no pressure signs
