i built a 1911 instead of a glock. i have started but the powder i am using are made by ADI, most of them are sold in USA under different brands.
A friend has a glock and he has started loading 135-145gr projies. he is using a powder that is out of production by he has a lot left so this might not help you.
he also mentioned to me that the double tap brass had a 10% fail rate, in that the case cracked, compared to reformed winchester and pmc 10mm cases.
what brass are you using??
