I ordered 200 Remington 150 grain Corelokts from Cabela's and I got the 170 grain version. I know it's a good bullet but my rifle is already sighted in for the 150 pushed by 29 grains of RL 7. I have a full can of 3031 so I will try 30 grains of it under the 170 and see if it is as good as you guys say. I used this bullet in factory loads in the seventies and it appeared that very little expansion was going on. Any comments on the current version.
