I fianally have my custom 300 RUM complete! I have also had a chance to shoot it some.

The rifle was built by Homer Strickland of Accuracy Arms in Anchorage as money permited.

After a brief break in period and a cleaning, the rifle's very first group measured .232"! The second group was .234"!! These were during load development and were of differant charge weights. So far I have 13 targets of 3 shot groups of various loads, different bullets, and charges shot over the course of 3 differant days. The average group size so far for the development is 0.5965"!! These are even unfire-formed cases. I am super extatic to say the least. There has been only one group to hit the 1" mark.

The only thing I am slightly dissapointed about is I seem to only get 3230 FPS safley from a 178 AMAX. Can anyone offer any insight?? Powder used so far has been RETUMBO and H-50 BMG. 102.0 H-50 BMG offers 3230 FPS and I am not comfortable going any hotter. 95.0 of RETUMBO sticks the cases at 3400 FPS.

The rifle was built on the Rem 700 ss action with a Lilja 27.25" #7 straight taper 12 twist, McMillan HTG stock in forest cammo, steel bedded with a custom desighned brake (kicks 1/2 as much as my 308!

.)

I have a 300 RUM with a Kreiger 1-13" twist, 27.875" barrel and have used RL22 to get 3350fps with 178-180gr bullets. This rifle seems to lean towards the slightly faster powders to get its best accuracy. Best load is H4831SC w/190 SMK at 3100fps, load is mild. 3 shot groups, .5moa to 1000yds, 3/8 at 100.

Congrats on your new rifle. with the shorter pipe, you are not going to realize the full potential of that large case.

Also, vel is not important relative to accuracy. You are definitely going fast enough.

You might want to look at heavier bullets if going LR shooting. The 178Amax is a wonderful bullet, but any 'low' BC bullet will not be as effective at LR as a high BC bullet going slower.

Nice shootin

Thanks guys,

I had just picked up some 200 grain accubonds today just for that reason. I figured if I cant drive em fast, I ought to drive em big!

I think the 200 Accubond is around .588?? Hope the 12x stabilizes them alright. I also am going to try RL-25 tomarrow.
