Well, there you have it, 50 rounds that you will shoot in one sitting, be it with a lot of cooling time in between.
This is the fan I ended up getting. https://www.amazon.ca/dskaoo-Electr...cordless+air+matress+pump,aps,140&sr=8-6&th=1
With the crazy price of components I usually do a single charge, plus 0.3 grains starting in the mid range area ladder test that I shoot at 200 m. I record all the hits on the phone through a spotting scope, and then analyze this data at home and decide which powder weight to concentrate on.
Then load 3 of each load right around the best groupings from the first test. Usually 3-4 sets of 3. Then work on my seating depth, again usually in 3 shot groups longer and shorter than the set length that was used for previous testing.
Then usually load up 5-10 and verify on one last group. You can do all this without a chrony as well.
