Why is that? Is there 3x the difference between a $300 optic and a $1000 optic?
I’m curious about that as well. What are the major differences that make it worth it?
I do agree with what WCB said to some extent but I definitely see a big difference in a $1,000 Zeiss or Swaro scope over a $500 Leupold, Vortex, SWFA or similar. The picture is much clearer, it is clear all the way to the outer edges, it gathers more light (VERY important at first/last light and in timber) and lets you pick out detail much better, like making you confident that what you're seeing between those two trees and one bush is the crease of an elk's shoulder, rather than just a patch of tan-colored fur. And perhaps the most important thing, the clarity remains when you turn the scope up all the way to maximum power. Cheaper scopes just don't do that.
My line of thinking has always been:
$1,000 Budget: $500 each for rifle and scope. You can do very well with both at this price point! (Winchester XPR and cheaper Leupold, Burris, Nikon, Athlon, SWFA, Sightron)
$1,500 Budget: Same $500 rifle with a $1,000 scope. You will love the improved glass! (Winchester XPR and Zeiss V4 or Swarovski Z3)
$2,000 Budget: $1,000 each for rifle and scope. (Browning X-Bolt, Weatherby Vanguard, Winchester Model 70, Bergara, not for me but Tikka and Zeiss V4 or Swaro Z3)
$2,500 Budget: $1,000 rifle and $1,500 scope (Zeiss, Swaro, NF, Kahles)
$3,000 Budget: This gets tricky. You start to get into some very nice factory rifles at around $1,500 - $2,000 (Christensen Arms Mesa or Mesa Titanium, for example) and I do see some benefit to these lighter, well thought-out rifles. I might drop back to a very solid $1,000 scope for a rifle like that.
These are just some things that I like. Others have their favorites and nobody is clearly right or wrong. We all like what we like.
After slogging up and down mountains for 45 years dragging along too many rifles and scopes to count and hand loading my own stuff, I have now settled into great comfort knowing that the absolute best factory rifles, ammo and optics are being produced right now. I would quite happily finish out my days with a new Winchester Model 70 Featherweight Stainless or EW, Browning X-Bolt Hells Canyon or Western Hunter, Weatherby Vanguard Backcountry/High Country/Weatherguard /Wilderness topped with a Zeiss V6 or Swaro Z5 and shooting whatever factory ammo the rifle liked best.
ADDED: I am a big-time Winchester and Zeiss fanboy, so take that for what it is worth!
