Ooops, my mistake. I ordered multiple springs and got 'em confused. Let this be a lesson kids, don't drink and drop items in your cart. It has this 10kg spring from Amazon. Yes, it is difficult to pull the hammer back, probably impossible for young nerfers. I also suspect it might be near the stress limit for the plastic hammer and trigger. For comparison, the BlasterParts Metal Hammershot kit has a 9kg spring.

I think LT is probably correct, it would be nearly impossible for people of average strength to prime a 14kg hammer with one hand. However, because of the design of the hammer/trigger interlock, it isn't necessary to have a stronger trigger spring. But having fired this Hammershot a few dozen times, I won't be surprised if the plastic trigger mech wears out before long.
