Does anyone make or sell any 11/32 screw-in adapters greater than 125grains and up to 200grains??
I have misc. BHs that I want 300gr total to use for small game with the arrows I ALREADY have tuned. I have never seen any and can't find any so maybe they don't exist. Thanks.

I don't think they exist. 125 grains is the heaviest I know of. There are limitations associated with the specific gravity of steel and the size of the adapter.

Think about using a 200 grain broadhead with a 100 grain adapter:

Or maybe a 175 grain broadhead with a 125 grain adapter:

You can get the Tusker Aztec as a 175 glue-on, or with a 125 grain adapter already glued in:

I know this doesn't get you where you would prefer since you already have glue-on broadheads of lower weights, but it's the only solution I know. Of course, there are always several models of 300 grain screw-in broadheads around.

125g adapter and 175g Abowyer or 225g tuffhead and 75 g adapter....or

Thanks for the suggestions but I am trying to use what I already have...trading time maybe.

Really not feasible to make a steel adapter more than 125 grain from both design and machining costs.
