Red, it all depends on what type of hunting you plan on doing. Mentioning that it’s a 30-30 sound like it’ll be in heavy bush so I would suggest the heavy duplex but if it’s open plain I would then suggest the duplex or wide duplex. I’m have never used the German reticles so I can’t comment on them. The dot is usually used for target shooting. The best thing is to go out and check them out in person if you can. Good luck....
