Reload the pipe and smoke again?

That's the way my Dad and Granddad did it, and they were satisfied pipe smokers for many years. My first job after college, I worked for a guy who smoked a pipe almost non-stop. I never saw him with multiple pipes. Personally, I try to limit my briars to one smoke, but sometimes not. Like most of us, I have more than enough pipes to not necessitate multiple smokes in a row. I see nothing wrong with your method, especially if you use a pipe cleaner between smokes. If the pipe gets sour, clean it. After all, they are hunks of wood meant to burn tobacco.

I do that all the time. My main thing I try to be mindful of the heat. If it has been smoking hot or wet, I'll let it rest so as not to risk damaging the briar. Other than that, as long as the blends are not ghosting or the tobacco tastes fine, then why not?

Mine depend on the pipe and what I'm smoking. If I freight train a pipe I let it rest. If it ends up being a wet smoke, I let it rest.

My poor old Grabow and my cobs will often get smoked all day long, several times a day.

I do this with my cobs at work, but not in my briars or meers at home. Not to say I wouldnt if the urge to smoke another came over me. But definitly clean and return to its home after smoking.

My father had only one functional pipe at a time and smoked it repeatedly throughout the day, week, month, etc. At the end of each smoke, he simply banged it out on an ash tray. He only ran a pipe cleaner through it when absolutely required and only cleaned and reamed his pipe when it became unsmokeable, i.e., the cake was so thick that it would no longer draw and/or he could no longer get tobacco into the bowl. He was happy with just one tobacco blend, too.

That said, he considered his pipe to be a utensil rather than a collectable or a functional work of art. He bought inexpensive pipes and smoked them until they fell apart. IMHO, he was a pipe smoker and I'm a pipe hobbyist. There were hobbyists in the past too, but I think the majority back then were smokers, whereas the majority today are hobbyists. Nothing wrong with either. Whatever floats your boat.

Do it all the time and it doesn't effect the pipe one bit, enjoy

There was once a time when I would never reload a pipe with the same tobacco,’or heaven forbid another blend. Lately I’ve been more relaxed about adhering to the ‘sacred pipe rule’. Life is too short for me to get hung up over trivial matters. Yesterday, i smoked three bowls of KBV Burlier Morning Pipe in the same pipe. I say do what makes you happy.

I smoke the same pipe twice per day for a week before changing pipes. Sometimes longer.

I reload all the time. When I'm out and about for the day, I'm not carrying a bunch of pipes. Maybe the Joe Case bent egg, because it's a real handy size for carrying and clinching, and the Devil Anse cause it's even handier and fits in the tobacco pouch in my saddle bags or jacket pocket. If things look like they might could eventually get a little woolie, I'll switch right over to the Devil Anse. It has nothing to do with what tobacco I might be smoking. I'll smoke anything in anything. I'm cowboy like that. Any saddle on any horse, it dont matter. Just get 'er done.

I do it all the time, I cant be bothered with several pipes and blends in the shooting/ fishing vest. When at home, and if I think about it I mat switch pipes but I really need to put an effort into doing so.

Let us settle this once and for all gang.. When someone buys a "Seven Day" pipe set..how many pipes does the set include? does it have fourteen? Twenty-one? Twenty-eight or even Thirty-Five?? No...... it will have SEVEN. One pipe for each day of the week, anything more than that is the preference of the pipe smoker.

Yes, I do that. But most of the time, I am at home, and just grab a different pipe. 
I do batch cleaning, usually a dozen or so at a time. 

I would smoke a pipe about once our twice a week in the summer months, so this isn't an issue for me. However, on those odd occasions where I have the opportunity to smoke another bowl, I usually choose another pipe, just so I can experience a different pipe.

If I'm out somewhere and have the opportunity for more than one bowl, I'll just reload the same pipe. I've never had an issue, but I would run a pipe cleaner though the shank and bowl for good measure.
