CROSMAN vs UMAREX C02 (Surprising results) 

Nice video. I've never used Crosman before but I hear that Umarex is cleaner. That's been the main reason why I have only run 12g Umarex carts in my TCP. Power-wise I never expected big differences but some report them. To properly assess the statistical significance though you need to do an online 2-tailed T-test plugging in the number of samples, the average among the samples, and the standard deviation (also called variance). It will give you a P value. P

Thanks for the much needed review. Last year, I bought 3 40packs of the Crosman cartridges for less than $14. each

This was exactly the information I was looking for. I really appreciate your scientific approach. Now I can rest easy knowing I got the best product for my kit.

Thanks for this excellent comparison of the two CO2 brands. The results are certainly food for thought.

This was a fantastic test. Thanks so much. Excellent!

Did you used any lubricants? Silicone spray or something like that? Will it make a difference? Did you try? Would be great to see. Thanks

You didn't control for humidity or atmospheric pressure though. And you did not measure the before and after weight of each cartridge

I think these tests can go either way

I've seen vids where umarex is way up on Crossman. I wonder if it makes a difference what pistol you're using 🤷

Thanks for the data.

That was a very good and interesting comparison on the two different brands of CO2 cartridges. Now, would it make any difference if you were to test again with another weapon? Would the Crosmans come out on top again? I like your channel, you have a new subscribers.

Fluke have done many many test have never had crossman out perform umarex co2 very strange......

Is this HDP 50 stock or did you do some mods?

Nice video and yes I subscribed 👍😉

Here is what I am seeing compared to what i experience. 1st of all. your Umarex look like my Crosman and vise versa. The cartridge w/ a narrow shoulder is lower filled than the cartridge with the broader shoulder.

Brother ,can I say that if the neck of the cartridge is fatter , the gas is more , which maintains the shots more energy ~ ？xd
