Hi Tek question

[Grmps]

Hi Tek rules to help avoid problems:
1)don't use to much coating
2)don't coat/tumble/swirl to long
3)MAKE SURE COATING IS COMPLETELY DRY BEFORE BAKING
4)It helps to pre-warm the bullets either set the pan on spacers on top of the countertop convection oven or use a heat fan if you had a house oven
5)make sure oven is set to reach 385 - 400 degrees in the middle of the shelf you bake on
6) make sure you bake long enough (12 min is safe on most countertop ovens with testing you can trim bake time off ) *baking to long does not hurt performance, it just darkens the coating.
Hi-tek coating (actually a stain) is a great friction barrier BUT is not a substitute for proper bullet diameter to bore size and proper alloy hardness for the caliber.
I concur with texas G about cutting the sprue to soon on a hot mold, the coating looks a little grainy meaning you tumbled / swirled it to long -- when the sound starts to change (15-20 seconds) the bottom of the buckets starts to dry out, dump them. it's OK/ better to dump them a little wet than to dry.
If you don't have a PID setup on your oven, set 2 oven thermometers i the middle of the shelf you bake on and adjust the oven temperature until they read 400.
Lining the bottom of the oven with ceramic briquettes/ fire brick/ (any hard substance that retains heat) will help the oven maintain temp and recover from opening the door.

What sizing equipment are you using and what gun are you shooting these out of?

Tumble lube the coated ones with LLA or whatever and shoot the coated ones. Tumbling too long leaves a rough surface that can get pulled off when sizing. Clean the sizer good and use a bit of H2O (anything else will contaminate the boolits so coating doesn't stick - except HiTek lube) as a lube in the sizer. Dirty or leaded sizer can scrape the coating. I just use the choreboy on the sizer.

Lone wold barrels are notorious for poor throating, Causing bad leading.

what is hytec and where to get it?

Hi-Tek is a polymer coating(stain actually) developed 25 years ago in Austrailia to coat lead bullets with eliminating the need for bullet lube and limiting a person's contact with lead. Typically 2 coats are applied.
