Every batch of metallurgy is different. Usually the springs with the smallest ID have greater fatigue stresses than larger ID's.So, in general OEM springs last the shortest cocking and firing cycles. Followed by Vortex springs then ARH's springs. YMMV.-Yogi
Personal experience is king, as the variables present in each case could fill a phone book (remember those?). Shoot the new Vortek spring out and you have an answer.That being said, it's not difficult to find accounts of Vortek springs losing velocity early on, relative to other aftermarket makes. Some heavy-duty shooters as well as many professional tuners don't use Vortek springs for that reason. The why's center on both the geometry and the material of the springs.
Thanks for the replies fellas, I hope this spring lasts longer than the factory one did, $60.00 repairs over and over add up and it seems almost like a design flaw in the rifle, I don't want to have to keep doing this. I did search the forum for old posts on this topic and one fella said he's had over 7,000 shots on his replacement Vortek mainspring, but it's been a long time ago and I'm curious if the spring material has improved since then. I shot a few more pellets this morning and I sure am happy with the results 👍

Once you have decent spring guides, springs should only be $20-30 bucks.-Yogi[/quote I'm not sure why I needed the grumpy emoji's but whatever... and having to replace a mainspring every 6 pellet tins seems anything but "normal wear" I purchased the Vortek mainspring and piston seal based on positive feedback from others who have used these products. I am completely aware that these parts are consumable items, all I asked was whether the Vortek springs will last longer than the factory mainsprings.
Wes,Sometimes Yogi over-does-it .
As some of you know I just installed a new Vortek mainspring and piston seal in my Diana 350 .22 and I was wondering if anyone has any experience with the Vortek springs and how well they hold up compared to the factory mainsprings? I bought the OEM drop in replacement version. The installation went well and the rifle has certainly gained power, not sure how much because I don't have a chronograph but it's shooting through 3/4" pine boards at 30 yards and before the new parts it wouldn't. I'm just concerned this is a chronic problem with these rifles and I was wondering if the aftermarket spring will mitigate this somewhat aka more shots before another mainspring replacement?
