I load them in four calibers, .243, .277, .284, and .308.
They are a good deer and black bear bullet. They are surprisingly good in the accuracy department. Years back I was very unhappy with the accuracy of my then new Ruger in 7 Remington mag. I had tried Remington, Winchester, and Federal factory ammo in it and they proved to be inaccurate in that rifle. I found that I had a keeper when I loaded the Remington bullet in front of H4831.
In 30-30 factory ammunition I have found the Remington Corelokt to be the most accurate in my rifle. After testing the big three brands.
In .277 the 130 grain and the 150 grain have proved themselve to be accurate.
I believe that a powder that comes close to filling the case is a very important ingredient in the accuracy game. I suspect that many times in the distant pass factories selected powders that would flow in automatic loading machines. As a kid we would do the old shake test on a loaded cartridge. It was clear that most loads did not come close to filling the case. Reviewing Nosler Reloading Manual # three and an old Lyman manual most listed accuracy loads come close to filling the case.
I operate on the theory of safety first, review a number of manuals for the slowest burning powder that gives tops performance in a case, and then develope a load. Normally the slowest burning powder will occupy more space in the case. I have loaded Corelokts along side other brand bullets and found that they shot in the same group at 100 yards.
The greatest variance I have found in factory bullets was with the old Remington Bronze Pt. in .277. The variance exceeded 2 grains.
The "old" or the orginal .277 140 grain WW Silvertip bullet is very accurate. Test weight of a number of bullets was 140 grains on the button. The first time I fired this bullet at the range I could not spot one round with the spotting scope. I found it in the very small 3/8 group. Again the powder charge came close to the case neck. I do not know how this bullet will react on a deer.
