Thanks.

what the heck is a 284 Jarret?

MD

fyi I shoot a 7 Mashburn Super and old cat from the 50's.

284 Jarrett is a 7mm/300 Win Mag

sounds to me like Jarret tried to do the same thing that Mashburn did about 50 years ago.

I've used the 7 Mash Super quite a bit, am on my 3rd tube. I use the 300 Win case to make my brass. Originally they used the H&H case and then when the Win Mag came out it became that much easier.

I have a 7mm/300 Win Mag and some data for the 140 Nosler Accubond. My reamer is throated to where the bearing surface for the 140 stops at the neck/shoulder junction. My rifle and another friend who built one tuned with IMR7828 at 77.5 grains. Another 2 for 4 total were built so far and another friends tuned with H4831SC. That rifle just went on a sheep hunt in Alaska`s Brooks Range. I don`t remember the H4831 load but I can get it if you think it interests you.
