Question of Bulldog 440

[DavideSpeed]

Hello to all guys, a greeting from Italy!

I saw the new crossbow Bulldog 440 model with 300lbs, I'm wrong or I'm the only one to think that maybe I'm a little too many 300lbs?
In the Excalibur site, they do not report the power stroke, could someone please tell me?
Are the limbs always the same as the other Bulldogs 380 and 400 or are they new limbs suitable for this crossbow?

Thank you have a nice day

14,5” of powerstroke!
I fear for the duration of the limbs!
