velvetant · Aug 16, 2012

Can someone do a quickload for me.
243 ackley improved and vihtavuori n165 with a 85 NPT and 95 NPT. Not sure the C.O.A.L. as I have not picked up some bullets yet to try.

25-284 with 115 NBT and vihtavuori n165, this one would have a C.O.A.L. of 2.950"...not a typo I seat them long in my single shot
Have four pounds of this powder and would like to find a use for it.

Thanks

My 243 AI has been with me for so long I cant remember when I got it. I use it for coyotes.
I did fire form 550 pieces of brass when I first got it, the brass is still going strong and I'm on my 3rd barrel.

The 25-284: Well I always liked the 25-06 and when I had a spare short action laying around I decided on the ballistic twin.
Now I really wish I did a 6.5-284 but at the time I didn't have a love affair with the 6.5 cal......My 6.5 Creedmoor will have to tide me over for now.
