thumper50, what I heard from my friend was between 25 and 30 I am hoping it will be a bit less than 30; it will be interesting to see how it works out it is supposed to have less pressure than 777 but more velocity so you should be able to get the same velocity with less powder but from what I have seen its only a little faster than 777FFF but if this is all true then I should be able to put together a mean hunting load. If you get close to 2000 with a 100 gr load and it has less pressure than 777-ff like they say what will a 150 gr clock out at?
This is not done yet but will be of interest to some of you when it is finished.
