I have shurched the net for info on useing HP-38 in the 30-30 and the 7-TCU.
With not much luck and in looking at the burn rate it is very close to the rate of Unique. I also know that Win-231 and HP-38 is the same powder just a different lable Win-231 is just a litle bit faster than Unique and is slower than Trail boss by a good bit. Any thoughts on this ive been loading for quite some time and Im aware of the rules of substuting powder with another. I have about 10 lbs HP-38 on hand and use it for my 44 mag, 38 spc,357 mag and 9 mm.
Im Wanting to use this in a Contender for a plinking load with cast Boolits both Barrels are super 14's
