Re: 300 RUM,Retumbo,200g Accubond
I am on my 3rd .300 RUM. The first 2 were Remington Stainless 700's and the new one is a Model 70 Stainless.
In the Remington's, (both) Best performance and .5 MOA accuracy was with H 1000 and Woodleigh Weldcore bullets. In both rifles, they liked 102 grains with the 165 grainers and I got 3477 fps averages. With the 180's, I loaded a grain less (101 grains)and got an average of 3407 fps in both rifles.
Tried the 165 grain loads on pigs, wild horses, and red stag ( about 20 animals in all.)and all dropped as if hit on the head with an axe.
In the Model 70, I began with some 150 grain Sirocco FActory ammo that chronographed at 3582 fps which is about 150 fps over factory specs. I changed rifles and put 3 more cartrisged through the Oehler 35P to double check the velocities and got the 3595 fps again with wasy extraction but plunger markes on the factory cases. This stuff is loaded very hot.
Next I began with hand loads and went over to Retumbo and worked up to 99 grains with the 180 grain BArnes triple Shock. Velocity was 3475 fps which is tremendous velocity.
With the 168 gn Barnes Triple Shocks, I loaded to 102 grains and got 3593 fps and loaded back a grain for better accuracy and still got an average velocity of 3522 fps which is right up there for a .308 caliber rifle.
I have since re checked the chronograph against previously accrued data and it is reading accurately.
Anyone else getting this kind of performance?
