When is the best time to chrony your loads? Ive heard that velocity will change on a clean barrel vs a fouled barrel. At what round count would you consider a barrel fouled and start taking velocities??

When to Chrony your loads

That will vary considerably from firearm to firearm, as well as with the bullet being used.. Start with a clean barrel, and you will know for sure if there is a significant difference between a clean barrel and a fouled barrel with your rifles, and your loads.

You are not "wearing out" the chronograph! Shoot all through it. I have a many year old Shooting Chrono - does not cost any more or less to shoot once or 20 times. Shoot clean bore, shoot dirty bore. Keep notes. Tell the world what you have discovered about your rifle.
I agree. Run everything over the chrono and find out what your guns do - then tell everyone what you found. It seems silly to ask a question that will provoke lots of strange responses when you have the tool to find out the real answer for yourself, your loads, and your guns. Except for the times I'm too lazy to set up the chrono, I run everything over it. It has taught me a lot of things.
I'm kinda surprised it was so quick. Interesting.
So do most of you guys just skip past initial few readings till the bore is fouled and calculate that into your average or take the whole string?? Or does it really matter at all? Been a long time since Ive really used a chronograph.
Cheers!!

Record EVERYTHING.
Look carefully at the numbers and look for trends, patterns, changes, accuracy, results relative to load data, components, lot numbers, adjustments or modifications to guns, results on game, or anything else you notice. You will learn more from your own good reloading records than you will from these forums. Forums are full of anecdotal "evidence" based on statistically too small samples of all kinds. If you record everything, after 20-30 years of loading for your own guns, you will have lots of real data from which to draw conclusions.
