You used my method ? Ok.
I've noticed that some 4a'a have even heavier thick sections than the Leupold Heavy Duplex, that and their more open feel make them a good choice for those that don't need the ranging/hold off or hold over qualities that I like in the duplexes.
What I thought you were trying to say was that the etched reticle of the Swaro was somehow sharper than the electroform reticle of the Leupold. That hasn't been the case from what I've seen. But it is if the user doesn't go far enough to focus both the reticle and each scope's image for the same range.
Nice to hear from you. E
