Devcon 10110 putty is the best I've used.
I stored it in the Fridge and it worked great two years later.
A guy on Longrangehunting did an experiment a few years ago ,he made some one inch blocks using JB weld ,Devcon and another epoxy of some type.
He didn't use any kits designed for bedding though.
Anyway his intentions were to measure the one inch cubes over time and see which bedding material would shrink over time.
Devcon was best that's why I ordered some ,but JB Weld has worked fine on a couple of rifles I bedded years ago.
Steer clear of the fast set up stuff as stated ,it outran me once and was a lot of work hogging it out.
