I am going to contact barnes but based on what has been posted here anybody see anything wrong with starting with 22gr IMR4198 36gr bullet wsr primer or 25gr IMR3031 36gr bullet wsr primer. I am using the winchester primers because small rifle primers are very scarse around here and I was able to secure 1000 of them plus the IMR powder I got with all the used equiptment I bought and have about 8# of IMR4350,4198,3031,and I think the other is 4064 which until I use it up will make for some very cheap reloading at the price I paid for every thing. Also I think I will mostly have to shoot these 36gr out of my short 223 encore with the 1-12 twist but what could I do to maybe make them shoot well out of the new 1-9 on my ultra? thanks Kurt
