Pellet weight too heavy?

[Laz]

Hey guys, its getting closer to finally getting my HW97KT and I'm curious to know if the JSB Exact Jumbo Heavy 18.13gr would be too heavy for the spring and even strain it to damage? Curious to know because I have about a 1000 of them. The darn H&N FTT 5.53mm are always out of stock everywhere here but JSBs are abundant and are good. After a break in with cheap ones, I have a Benji sample pack, JSB 15.89gr, JSB 18.13gr, JSB 13.43gr, RWS Superdomes, and some Stoeger X-Hunt's too try. I will try the JSB Express 14.3gr too.

18's quite likely too heavy for a 97K in .22 cal ... this JMO

It's on the edge... You can use it, you won't damage the spring, but you will notice a huge pellet drop after 30 yards, I would prefer the JSB 15.9 grain as better alternative.

Thanks guys, I am kinda iffy about it and will just save them for the disco.
