I need to pull the HVA M38 barreled action from the B&C stock, but am having trouble unscrewing the set screws on the Henshaw trigger shoe that was installed when the rifle was sporterized.
I thought I had every size Allen wrench known to man, but am wrong! None of them fit!
Can anybody tell me the correct size wrench I need to use to take out those pesky screws?
Thank you.
(There are no publicly available reference charts extant for the Henshaw trigger shoe line.)

Are they Torx and not Allen head?

Grab a Dremel tool and a cutoff wheel, shave a bigger one down until it fits.

I don't know the specific size that your shoe uses, but many of those set screws use tiny hex head screws that are not included in most sets. Your local hardware store should carry a selection. My guess is your need a .050, but they do make even smaller ones. They aren't expensive.

I ordered a set of “off size” tiny hex wrenches, including a .050. Ace and Flaig use that size, so hoping its a standard for shoes. Thank you for the suggestion. Will update when rec’d,

The new set of miniature odd-sized Allen wrenches did not contain a wrench that would fit these set screws. However, I was able to stone the .05 wrench to fit and got the shoe off and the rifle out of the stock.
Still not sure of the final size of the wrench required, but that shoe is not going back on the rifle to stymie the next person who needs to get it apart!
