7.7 Japanese help .
Posted: 26 Sep 2021 17:18
They strike again this time in a type 99 Sporter .
The situation .
The groove dia is .316 so for cast I need at least a .318 and it takes .320 to fill the throat . This ensures a gas seal and lead bullets are no match for 20-45kpsi so no worries there .
The current die set sizes for the spec .310/.312 jacketed bullets so it takes the neck down to and ID of .306 and back up to .309 . A new expander ball is a great idea except it's been a couple of years since Herters stopped selling dies . I can just make an expander of course but it's hard on the brass .
What I need .......
I need someone or several to pull the expander out of really any 8mm with a 2-2.25 case length , size and measure the neck dia . An 8×57 would be ideal . I need a neck OD of .344 ideal under is better than over .
I'm considering an RGB set as my actual chamber is closer to the 8×57 than spec for 7.7x58 .
Ps ;
Titan Reloading has set up a life time discount club that takes Email attached orders back to I think April 2017 for values with a how much you've spent discount scale . I think its stepped at ;
$100 @1%
$500 @2%
$1000@3%
$5000@5%
I missed a step ...... Its not much but it doesn't take much to get to the first step and it's not a huge discount but they already sell well under MSRP .
