If you haven’t used this product yet, you really should. It’s just simply awesome. I was stuck in the rain with my blued Sako 300 win mag a couple of years back, which i had treated with this product when i bought it. Well, long story short, i got home so tired that I forgot to wipe my rifle down for weeks! When I remembered to do it, i was expecting to see rust for sure. It looks perfect! This stuff really works and it will improve the accuracy of your weapons too. Try it. It seems to add some velocity to the bullet because after you apply to the inside of the bore, your bullet will rise which indicates to me that it’s traveling faster. I don’t know, i’m no expert, but bottom line is I now treat EVERYTHING I own with this stuff . . . yes, even my cars. They have specific car treatments! look them up!
