For a long while I thought bullets were not that great for snuff. Lets face it, they were around a long time before the snuff revival and really made to snort other powders where you need a much smaller dose than the average pinch of snuff. I always found that a medium snuff would tend to clog a bullet and every other dose would be a blank, ie, turn, tap, sniff but nothing comes out. Thats because a little plug of compacted snuff forms just before ther dose chamber. I also found that I would need several hits to equal a pinch. Anyway, in the end I made the switch to full time snuffing by just using the pinch. A while back I tried Dholkia white and found it so penetrating that even with 30 odd years snuffng experience I would get it in the throat half the time, sooo I tried a Toque metal bullet. This proved excellent and, for me, gives a hit something akin to a pull on a cigarette. I figure the standard advice of stopping smoking by pinching snuff whnever you need a cigarette would work very well with white and a bullet. If you are at the stopping stage and still not figured out the exact way to stop just try this: fill a bullet with white, a toast/scotch or Indian fine snuff and whenever the urge to smoke comes on take two doses from the bullet. If anyone is at that stage I would be interested to hear what you think…
The main mistake I made was to go for the snuffs aimed at the quitting smoker (McCHrystals S’Nuff, toque quit). If I had stuck to them I would never have given up the ciggies as I found them too much for my newbie nose. Instead I put together a moderate order of a variety of snuffs and then found a few that I liked. After that the migration from cigarettes was made a lot easier as the snuff was an enjoyable experience rather than an eye watering baptism of fire! McChrystals blends allowed me to use enough snuff to quell my nicotine cravings without excessive pain, and would consider it a good start point as an introduction to the move from smoking to snuff. I have enjoyed the Toasts I received in the post today, however if that was my introduction to snuff I may have progressed no further and may still be chuffing away like a good one 
I used a bullet with Brutons today, and took too big of a sniff. I coughed and the dust puffed out of my mouth.
I prefer a pinch, however I played around with a bullet for a while. I found it best to not block the other nostril when using the bullet, and to inhale as gently as possible. Rather not inhale hard enough and try again than send it shooting down my throat and into my sinuses - now that does hurt!
whether bullet or pinch you still need to go gently
