20/222 load
 

Right guys just finished bottle off v133 I was using in my 20/222,cannot get this powder any more here in Australia was thinking off using 8208
What is everyone else using and how much
Cheers jack

I use H322 and 40gr Bergers in my 20-222. I'll have to look later when I get a chance but if I recall I'm using 22.5gr H322 with those 40's.

Fair dinkum Jack, 2207 or BM1 are the answers to your prayers, I use 2207, cause I have a heap, Marcus uses BM! cause he gets good speed out of it and flows better through the powder measure. :)

I use 8208 in my 20 Extreme with great results. 21.2 grains with either the 40 or 55 grain Bergers does the trick. It is a bit of a stout load so start lower

Hey camel was going too try benchmark 1 but was talking too tony z the other day and he’s using 8208 with good speed and accuracy.
Thanks for the replies guys will be using 32grain zmax as I have a 1000 or so off them 5o use up

Yeah, Tony Z seems to like 8208, not much difference in the three powders from what I can see, guess it comes down to which one is readily available in a continuous supply, I buy 2207 mainly because I can get it easily out here in the sticks, it works well in my other 222 based cartridges, and when I started with the 20/222, its what I had, haven't seen the need to change. :)

Ok update on load development tried from 19.5 up to 22 grains off 8208 going up in .3 to .4 grain intervals looked promising right from the start, first session was 19.5 up to 20.7 nothing overly ugly then asked tonyz were he got to with his 20/222 so back to reloading room and start at 20.7 too 22 grains.started at 200 yards 20.7 still looked good up I went to 21 not good opened up so onward and up 21.4 not bad then 21.7 looking good measuring 5 shot group.78 one stepped right and up next 22 grains 5 shots .588 from memory so very happy
So now any body tell me what sort off speed that might be
