I picked up one of the covenants 24 power in second focal plain to put on my savage stealth in 300 win mag. For 250 bucks I and everyone who's played with it have been very impressed.
I'm at around 80 rounds with no issues, reticle is crisp (its not as thick in real life as it shows on cabalas website), glass is clear and very comparable to the vortex diamond back line, adjustments are positive and on the money, eye box is decent and I didn't have an issue getting the reticle crisp and targets to focus at longer ranges.
The tac 32 reticle is very, very easy to use and with my data entered into strelok it was dead on at 500 (plan to test at longer ranges when the weather cooperates). Buddy and his 15 year old son both tried it out and had first shot hits at 500.
The only downfalls are it lacks a large amount of elevation adjustment (40 moa) so if you like to adjust by clicks it may not be the scope for you unless you have a 20 moa mount, and no zero stops on the turrets. I like to sight in at 100 and use the reticle so this did not affect me.
I've had a chance to use some higher end optics (night force & vortex viper line) its not them, but all and all for the $ I have no complaints and plan for pick another up for my wife's 308 build.
let me know if you have any specific questions.
