Sure. I use Vyse brand ordinance gelatin and follow Shawn Dodsons procedure at
www.firearmstactical.com . I bet there would be many people here interested in your 6.5 Grendel results, myself included.
Gelatin is actually pretty simple to make (at least it is now after two years of doing it
). Basically, I used to follow the above procedure to the 't' but have modified it recently in the interests of saving time. What matters is that the block calibration information is recorded and the block has been given enough cooling down time to reach a complete cure, so whatever gets the block there is just as good as anything else.
I generally now skip the '4 hour hydration period' - after the solution is poured into the mould, I place it immediately in the fridge. To help speed cure time, I elevate the mould off of the refrigerator surface (using two pieces of 0.50" square tubing, the higher the better) to let the colder air circulate under the mould and also place the mould in the stream of colder air being blown by the refrigeration unit.
Please look for blueprints of an aluminum mould with integral cooling fins in the near future - I am looking to reduce the cure time significantly by increasing the effects of the free convection. They will be put up on THR when I get them done.
Oh, I use 10% gelatin powder concentration - 20% is for rich people.
