Re: combined technology bullets?
I have a Win M70 with the BOSS chambered in 300 Win Mag and have fired many hundreds of Lubalox coated BST bullets and Fail Safe bullets, have not encountered any kind of build up, the BST load still prints 3 shots into a triangular 1/2" group and sometimes better, have used the same load since developing it in 1998....
My positive experiences with the CT Lubalox coated bullets were the direct result of going to coated bullets for all my guns, have used moly but won't again, Have been coating all my bullets with tungsten, both jacketed rifle bullets and hard cast lead bullets for my revolvers......
Like Lubalox the tungsten does not build up and is very easy to clean, moly on the other hand is difficult to remove if allowed to get out of control and will rust under the layers of copper fouling and start pitting your bore
