I was working up some new loads so didn't shoot long range. I kept it to 500 yards to find the most promising loads and then carry them out to long range on my next trip. All the bullets shot well enough to satisfy most hunters and none shot poorly. However two loads in particular were outstanding with accuracy and velocity spreads. Both shot just over two inch groups at 500 yards. One was the 208 Amax with H-870 powder and the other was the 200 grain Cutting Edge with Retumbo. The Amax was loaded with 103 grains H-870 with a fed 215 match primer and seated to an oal of 3.829". The velocities were 3137, 3139, 3136, 3137 and 3139 in a five shot string. This is a light load but just shot like a dream. I drove the 208 Amax to over 3200 fps with no pressure signs out of the Schneider polygon 26" barrel with H-870 at various seating depths but the accuracy node was right here. I shoot where the accuracy is and let the rifle tell me what it likes.
The other top load that was equally accurate was the new 200 grain Cutting Edge bullet loaded with 93 grains retumbo at an oal of 3.984". The velocities were 3334, 3333, 3329, 3335 and 3333 fps. Again just over 2" at 500 yards. I have been looking forward to testing this new offering from Cutting Edge after the success I have had with other bullets from them. They list a BC of .62 and I plan to test that independently as the summer progresses. I know Durvin at Cutting Edge has tested it with actual long range drops as he does with all their bullets and has it down pretty close. It is a beautifuly sleek bullet quite a bit longer than the 210 Berger or the 208 Amax. It shot well out of the 1-10 twist barrel even though it is very long.
I was anxious to test this bullet in the EOL Outdoorsman with the Schneider barrel to see if I got the same results as with some of my rifles. For some reason the cutting edge bullets shoot up to 75-100 fps faster than standard lead core bullets with what seems to be equal pressure loads. Something in the alloy and/or the design of the bullets maybe. This bullet was no different in the Mcmillan rifle. It shot 80 fps faster than what seemed to be equal pressure loads of the 200 grain Nosler Accubond which also shot extremely well in the test. This tendency combined with the high bc per weight of the Cutting Edge bullets give them an advantage at long range shooting. They are extremely accurate and have not been critical to seating depths in the rifles I have shot them in. 3330 fps is fast out of a 26" barrel 300 RUM with a 200 grain bullet however this did not show pressure as a hot load. I regularly shoot 94+ grains of Retumbo with a 200 grain bullet in the 300 RUM.
It is getting late. I will get more loads in tomorrow.
My camera is not working so I can't get pictures up of the groups the past three days but some were very impressive. I thought it just needed batteries and it seemed to work fine taking the pictures but it will not download to my computer. Something has gone haywire in the internal electronics I think. I am taking more pictures tomorrow with my son's camera.
