Can I use this on a 22-250

I use it on 308, 40 rounds. No problem! (So far...)

by SamB, Verified Owner, March 26, 2026
I see a lot of reviews for 22lr shooters will this scope handle recoil from a 308 or 6.5 CM ?

I try it on a 12lb. 308 with muzzle brake.
No problem!

Vector Sentinel-X 10-40x50 Review by Cliff, Verified Owner, June 1, 2023

I don't give many reviews but this scope is one of the best for the money buys out there. It takes a good scope to get the most out of the Anschutz rifles. You can only hit what you can see. This scope proves that you don't always have to spend $1000...

Perfect for 22LR 50yd & 100yd match use by HPK, Verified Owner, December 18, 2021
I mounted this on my $300 Savage Mark II 22LR for use in NRA and ARA 50yd and 100yd matches. While 40x may seem a bit long for such short distances, this is precision shooting and it really helps to have some good magnification. I especially like t...
