That's because you've chemically burned your nose receptors with the Hoppes.
🤪 It actually stinks to high heaven. My wife said "Oh hell no" when I first used it, even though I was in the garage. I have to say I see her point. Last time I used it was 20 yrs ago, but not just because of the smell....it's because...
...I learned something very valuable from a champion benchrester who had won a long range(1000yd) match I shot in many many years ago. I asked him after the match how he cleans his rifle. He said he didn't. One patch of CLP after the match to protect the bore and chamber and that's it. I asked how many rounds shot so far..he said over 800(BTW...he shot sub 5" on last group to win that day). He was a firm believer that over cleaning not only didn't help accuracy but actually hurt it (heresy!!). He explained that copper build up isn't a problem with a good barrel, and the small amount that does occur is self limiting. Shooting with a consistent small amount of copper and powder fouling was the key. Why remove it and then have to manage the build up during the match and the changes to velocity and POI that go with . Its part of the reason benchresters need to shoot a number of practice rounds before a match, not just to dial in to the target and climate, but to condition the barrel. It was a true revelation for me from that point on. I have proven the same point many many times to others over the years. The reason the whole overcleaning practice existed many years ago was because of the lower quality of the barrels. Its simply not necessary today.
