I shot couple loads with regular primer with RE-17
and 1040 gr slug in 12GA FH NEF, and it does great.
Tested loads that were cooled outside a while.Perfect ignition.
I fired loads RE-17 8ga plastic,in my 8GA FH on new NEF long
heavy barrel that was a 10 ga and RE-17 is great. No hesitation,
it fires off as good in 8ga as the 4759. Remember
I couldn't get good ignition in 8g with 4227, but so far
RE-17 is magic. In 8 ga all it would hold under the 8ga REM
wadcup with 770 gr slug is 200 gr of RE-!7, with the
wadcup pressed down, compressed real hard,good crimp,
and it really bellers.2400 plus.Going by case
expansion about 20k pressure. Which don't bother
those one piece compression molded super strong
8ga REM cases. You must have real tight proper
roll crimp in plastic cases and good tight
taper crimp or rolled in crimp in groove
in the brass cases. In RMC brass I size it so slugs
have to be shoved in with press.
And this RE-17 doesn't break up the kernels when powder
gets to a certain point, like the 7383 does, causing burning
rate to speed up more than what it was designed for.
I tested 7383 in my 700HE, and when up to 35-40k it's
pressure went up fast, much more than linear progression.
I still like 7383 at shotgun pressures, but I really like
RE-17.Just pour case full and shoot with lighter slugs.
Ok- for those who want to get into the 12GA FH and get
the long strong 3.85 inch cases Rob on AR got some made,
you can email him to get some-

He can also tell you where to get reamer.Ed.
