Re: Cutting Edge Bullets
I have been shooting several rifles the past week and just got off the range today. I am in the process of switching several of my rifles over to the Cutting Edge bullets after shooting them quite a bit at targets and seeing a few animals shot with them. So I thought I would add an update here.
I have been focusing on three bullets so far in the rifles I am switching. My 300 winchester loves the c21 180 grain and will hold under .5 moa to 800 yards with it. I have some excellent loads in my 338-300 RUM, 338 Lapua, 338-378 wby and 338 SIN with the 225 grain D62 bullet. The 338-378 is my favorite long range rifle and over the past week it is holding 6"- 8" three shot groups at 1000 yards. I dropped the velocity down from 3510 fps to 3460 fps to save brass and hit a consistent load with extremely low velocity spreads. All of these have 28" barrels except for the sin with a 24". My accuracy loads this week are 3235 fps with the 338-300 RUM, 3320 fps with the 338 Lapua and 3065 fps with the 338 SIN. These velocities may help some of you to know what you can expect with these cartridges shooting the 225 grain so you can run it on JBM and see if it is something you are interested in. These are not max velocity but where the bullets shoot good in my guns.
This morning I got my 300 RUM dialed in with the c32 180 grain CE bullet. It has a 28" 1-10 twist. Yesterday I shot several groups all good ones averaging 3510-3530 fps varying seating depths, and retumbo charges from 98-99 grains. My seating depth I feel I have right on now for best accuracy and today dropped the powder charges to 97-98 grains. I hit the jackpot at 97.5 grains Retumbo and a coal of 3.785". I hit my best group of 1.72" at 500 yards with this load. The velocity spread was 3462-3468 fps. This rifle is ready to hunt.
The best load in my 300 winchester, is with the bullet seated exactly to the depth recomended on the website for the c21 bullet. The 300 RUM and 338-378 wby best accuracy is with the bullets seated deaper into the case. I have never got better accuracy seating longer than recomended. So if you try these start out at the recomended depth and seat deeper if needed from my limited experience. These three I have nailed and am working on some others.
Predictions are difficult, especially when they involve the future
