MikeBurke300 Whisper
Does anybody have any reloading data for the 300 Whisper shooting 200 grain and 220 grain SMK. It is for a bolt action rifle. Any data with N130 would greatly be appreciated.
I have been shooting Corbon ammo loaded with the 220 grain bullet. I have enough brass to start reloading so any info would be appreciated.

Ol'SpookMike, N130 is very close to AA-1680, which does well for me @ 10.3 grains....assuming you're shooting susonic?
N110,H-110, and AA#9 also work well in this caliber.
Lost of 300W info

DuggaBoyehaven't used N-130--
My best accuracy with the 220's came with 7.5 gr of AA- No. 5.

MikeBurkeThere is a load with 10.5 grains of AA7.The load Ol'spook posted is 10.3 grains of AA-1680.
The N-130 burnrate is between these two, I think I will start with 10 grains.
My rifle is built in a Stiller action, 40X stock and trigger, with a Lilja barrel. With Corbon factory ammo it shoots one hole groups at 50 yards.
