I'll start off with why I went with the 284. Last year I put together a 7 SAUM with a tikka prefit for my brother in-law. It is a carbon six barrel and it has been very accurate from the beginning. The problem is that SAUM brass is hard to get unless you are willing to pay the price gougers. I am not!
I went looking for different options that work well with a tikkas COAL restrictions. The 284 caught my attention. I knew it would not have the speed of the SAUM but I could get Laupa brass anytime I wanted and one of the top powders is H4350 which I have a lot off. I decided to give it a try. Worst case I am out $450 for the barrel. Every thing showed up this week and I put it together Thursday night.
Specs:
-24" McGowen barrel, #5 Douglas contour. For those wondering this barrel weighted 3 pounds 5 oz. I used their 284 Gap Reamer.
-Ross 4 port break
-Leupold backcountry rings
-Trijicon Credo 4-16x50
-Mtn tactical trigger spring
-Tikka vertical grip
-Total weight is 9 lbs 5 oz
Everything else is stock besides the kydex cheek piece I made myself.
I started by loading 4, 162 ELDMs. I began at 52 grains and ended at 53.5 grains. I shot them over the chronograph and was plesently suprised! 53.5 grains showed no pressure and was 2909 fps! I was hoping for 2850. I went home cleaned the barrel and loaded 5 more at 53.5 grains. This resulted in an average speed of 2911 with an ES of 15 and an SD of 6. Things were looking good! I cleaned the barrel again. Loaded 5 more and shot the next 2 over the chronograph again. Both were 2906.
At that point I took off the magnetospeed and really focused on shooting a 3 shot group. The 7 shot group with the magnetospeed was probably less than 1" but not by much. Maybe 7/8"ish. I CAN NOT normally shoot a group like this and it is not likely I'll shoot one like this again. This could be a fluke but things are looking good so far.
I will keep this thread updated if people are interested. There is a lot of info out there for the 284 but 95% is focused on f-class shooters. Hopefully this can help people out a little and provide some info I was looking for when wanting to build this hunting rifle.
