I was shooting by spitfires tonight, well actually just one because i didn't want to ruin any other ones and after about my tenth shot the retention clip bent and now it won't shut all the way. I was shooting to the Block. Is there a way to keep them from opening or a way to not ruin them.

The same thing happened to me a couple days ago when I was shooting a Spitfire, trying to decide whether I wanted to try it on deer or not, I shot it one time after it bent, and broke the blade off right above the clip. I cant believe a blade broke on a Carbon Block, or any other target! [:@]

Thye have pratice wings for those things, which simulate the real thing.
for some reason those broadheads don't do real well into foam targets.
Don't fear though they are devestating on a real deer.

When shooting into foam, I will use a couple of wraps of dental floss around the blades to keep them closed after impact.
Allows you to practice as much as you want without bending blades or dulling them.

Bees is right. Drop the $10 on the practice blades and stop worrying about breaking sharpened ones. You shouldn't hunt with blades that have been used on a target anyway. One of the problems with using mechanicals on foam targets is that the foam gets into the slots where the blades go. You have to really clean it out after every shot or your blades may open in flight or break. The Spitfires are worse because the foam gets behind the retention clip also. If you can afford it, buy another set of Spitfires and a pack of practice blades. Use the old ones just for practicing and the new set just for hunting. When deciding if you can spend the money, imagine that you are looking at a 12 point buck of a lifetime and wondering if you cleaned out your broadheads enough to be totally confident in them. Makes my decision easy.

NAP advertises that you should replace the retention clip and the little bolt that holds in the blade and clip after every five shots. Ooops I didnt do that. G2 shooter is right about crap getting into the retention clip. I usually end up taking mine apart and cleaning them out before a hunt. I do this after I get a deer as well.

I would reccomend taking the retention clip out and trying to straighten it out. If not, you will undoubtedly be able to find it the clips at a well stocked pro-shop.
