I have used both. Although it's been several years since I used JLK. The JLK's worked well for me with hunting whitetails. I used their 185's. I now use the Berg 215 hybrids. When I quit using the JLK's it was not due to anything negative, I just decided I'd try the AMAX, then went to Bergers. I think the JLK's are a great bullet.
