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!
