Hey gang,
I am a long time service rifle shooter (one of those weirdos that uses a sling) and this is my first precision rifle with a scope and bipod.
I bought the rifle new and as of this writing it has 300 rounds down the pipe. After testing out a few different bullets I have decided to stay with the 175 SMK for my loads. I have put everything from 155's to 178's through this rifle and it will shoot everything into the neighbourhood of 1/2 inch. Even 7.62 Nato M80 went into 3/4" consistently. I freaking love this thing!!
I went out today with 5 different charge weights to try the 175 SMK's seated 25 thou off the lands with IMR 4895 powder in lapua brass and CCI #34 primers.
I loaded 40, 40.5, 41, 41.5 and 42 grains. No pressure signs at 42 which should be well over 2600 fps in that barrel.
I am still getting used to this type of shooting and frequently send one round out of the group but I am getting better each range session.
The gem of the day was my last 5 test rounds at 41.5 grains which came in at .268" !!! I really hunkered down and gave it my best on that one and I did not screw it up for once!! I have never shot a group that small in my life!!
So 41.5 looks like the ticket giving me two good groups: 5 rounds into .268" and 4 rounds into .227" (I screwed that one up with a flyer).
The results were as follows:
(all are 5 shot groups)
.268" 41.5 gr
.333" 41 gr
.428" 40 gr
.504" 41.5 gr (flyer) .277 without the flyer.
.709" 40.5 gr (horrible flyer)
.781" 42 grains (flyer)
It definitely opened up a bit at 42 grains which is getting a little warm anyways.
Next I need to scrounge up a chrony and see what kinds of velocities I am getting and then on to the dope and off to the races. I also ditched the rear bag setup when using this rifle and find it is steadiest with a block of wood under the ground spike so I can make fine adjustment from there.
Hope you enjoy the pics.
