I just ordered a dozen of the 300s. I was wondering if anyone else uses them or has tried them?

I used ' em and they are very accurate.I did have a couple break from deflection on the shot and that was mostly my fault--overall i' m happy with the job they do.I think you' ll like the penetration they get.

I have hunted 2 seasons with ECE' s, and am very satisfied. I use the 400' s on my setup.

FYI, they are the same arrow as the Bemn ICS. So if one happnes to be cheaper than the other you will be gtting the same thing.
