I have used Brownell's Accuglas jel for 40 plus years. Never had problem.
I too, have used Acraglas Gel…..for about 30 yrs.
Don’t see a reason to quit now. It’s easy to work with and results have been fantastic. I will say, one time(years ago) I got rushed/sloppy with measuring and mixing a batch of it and it didn’t cure right(was soft).
So, I dremeled it out of the stock and started over….problem solved.
Just follow the instructions exactly(not hard as it’s a 1:1 mixture).
I tend to be a bit OCD and will usually stir/fold it for a good 5 min. paying particular attention to scraping the sides of the mixing cup to ensure all is thoroughly mixed.
So far(30 yrs and probably 30 rifles bedded) I have not experienced any loss in accuracy or noticed any dimensional changes or loosening in the bedding.🤔
Good stuff in my opinion.
