17 Remington load data needed

[sbranden]

Anyone shooting IMR-4320 in their 17 Rems and if so, can you share your loads please? I found a buddy who had a pound of this powder on-hand, so plan to take it off his hands now.

Also, for whatever anyone is shooting in theirs - have you found this caliber to be very finicky about seating depth? I'm trying to figure out if I should be trying to seat as long as possible (or what's even possible with 25gr hp bullets), or if I should be able to find something 1/2"@100 capable at 2.150" (published OAL).

Well, got my hands on a jar of 4320 yesterday. Probably won't get back to this project until Feb or March now, but will be watching for any other good inputs.

Mine was most accurete 15 off the lands

but it was minute of mouse at 10 off and 20 off also....just a little tighter at 15 off

Yeah, that's what I figured. The guy at Woodchuck Den who I bought my first box of 200 from (25hp, .050's) seemed to suggest I try to tuck 'em up to the rifling pretty good.

Get that new seater stem in and with this 4320 powder now, well... I will probably try to get my buddy to swing his gun by so I can do some measuring before loading up another batch.

Thanks for this feedback.
