I got the 75gr screw in weights because I like heavy arrows (even on my crossbow)I use 2 on my crossbow arrows and my vertical compound I shoot a 765gr arrow and it destroys bones including the humerus and the ball socket joints. My crossbow shoots 303 with the same weight cross bolts but for this build I’m at 660gr and shooting 330fps plenty if you ask me. I give these weights a 5 star because they fit perfectly with no fuss, (.300” i d) the only thing is it does require a special tool for installation which I have already so no complaints

There are different than the last ones I got last year.these are shorter and fatter. Perfect fit for the bolts(Zombie slayers).I use blue lock tight but these are a better/tighter fit. 5 star rating
