The guys here have it summed up well. If you are not a member of snipershide, RUN to join. Their version of the swap meet is unfucking believable. It took me a bit to learn what everything is since I’m on my own up here but once I got to the point of knowing just enough to be dangerous, I went thru it like Sherman marching to the sea.
I bought all 4 of my bolt guns, 2 Hensoldt and 2 S&B scopes, magazines, mounts, bipods, tripods, LRF, cases, etc. from there. Like PB said, the LR/ELR guys are a finicky bunch. Not quite like the knife guys but close. People apologize, take close up pics and circle even the lightest scope ring outline. It’s amazing to see but you can get some screaming deals. Be patient and your brand, power and reticle WILL pop up eventually. Huge deals on S&B 5-25s like I have never seen.
I eventually will try a Horus type reticle but I’m a S&B P4F devotee. It is very popular and for me at least, easy to use. My Hensoldts are 4-16x56 with their NH1 reticle. I don’t do QD mounts on my bolt guns. I use Spuhr and Recknagel mounts.
The Hensoldt 6-24x72 is known as the “Hubble” by shooters. It is a sight to see as it were. The Hensoldt 3.5-26x56 is the best scope I have ever looked through but for $7k, it best be.
The NF ATACR in 7-35x56 is a smoking good scope. You can hammer nails with NF scopes
Kahles is a solid choice with a great eye box and glass. Their LPVS for 5.56 or 7.62 guns to me are better than the Short Dots.
I have some Steiner “ACOG” type fixed power scopes on a couple of carbines. Their glass is very nice as well.
Calibers are a separate thread but just to follow what pointblank said, the dreams of mile + shots and the equipment to go with it are usually just that....a dream. I loved the .408CT rifle I once had but that round can almost shoot across my state. Even my current .338LM is WAY too much for me . Classic case of eyes way bigger than your stomach.
Except for high end shotguns and double rifles and machine guns, LR/ELR shooting is a fun but wicked expensive hobby.
