Delta 4blade with 100gr adapters

[ymountainman]

Hey I just picked up some steel 100gr adapters to put in my 4blade Deltas and they don't reach all the way to the bottom, so i have a hole. I don't want the hole, Do I? I figure it will whistle? I shoot a nonvented broadhead because they are so quiet. What do yall do with the Hole? Thanks!

Cliff,

That's been my experience is that they will whistle... don't think it makes a difference, but I've also been told that it a place that make the head more subject to fail at that place...

In the Delta's the only adapter that I know of that reaches across the gap are the old Sweetland Longs, which are next to impossible to find anymore...

I got a few packs of em that I don't use for the same reason.      

Wish I knew where to find the "perfect" adapter.....

I know Terry is a diehard delta 4blade guy. Maybe he can help.

I've used 4-blade deltas with shorter inserts in the past such that the bleeder blade slot wasn't fully closed.  Never had a problem with them making noise, and never had a head/insert fail on aluminum arrows.  The gap that's there is pretty small.  Could probably drizzle some hot melt on it to close it.  Some fill the front part of the taper with lead shot first to increase point weight.

Thanks Guys!The steel adapter is hollow. I cut the end off a 16penny nail, about 3/8 inch. I fit it where it was snug with the adapter made up. I jb welded it in place and the hole was filled with the jb. I weighed it and it is 257grains on my Rcbs scale.Im gonna let it dry and shoot it tommorrow.I hope it works. Thanks.

Good idea Cliff.

There was a shortage a while back on aluminums ....like last year this time....but I've never had a problem other than that....and I've got a hundred pack of two different kinds....both work and fit like always....I'm talking about the longs.

I've shot the shorts...and some whistle and some don't....that was decades ago...just went to the longs and stayed there....makes them more durable too.

Don't know much about he shorter steel ones though.

Virtually all long adapters will leave a gap in the Zwickey, I don't like it either so I usually fill it up with hot melt.

We carry the Sweetland X-long adapters for just this purpose, they fit great and no gap.  They are only 36 grains though, so if you're shooting higher point weights you might need a brass insert to boost things.

You can stuff a little cotten in the gap.  One of your wife's cotten balls will do a bunch.

alot of different ways to fill that gap. I cut the tip of a point tapered wood shaft, just a little piece....
