My 98 Mauser that was sporterized is finicky on loading cast boolets. I've been using the Lyman/Ideal 358318 RN to feed from the magazine for this 35 Whelen rifle, but can't say I am enamored with that particular slug. FN boolits will not load from the magazine at all if they are full length, a common malady with these.
The other day found in my kit some 158 Hornaday Hollow point jacketed SMC's I loaded 20 years ago for fun. Shot a few for old times sake and it was very pleasing. They are short enough to load flawlessly from the magazine well. With a hacksaw, drill and a couple files I took the 358318 and turned it into a 180 grain LFN boolit, which is the weight I was looking for:

This matches the hp swc for length perfectly:

If I keep the exposed portion of this wide flat nose (.250" meplat) to .30" then this, too, cycles perfectly in the rifle.

Problem, I can't find a current mold maker that makes something akin to this with a gas check design. I want to potentially spit these out from 1,800 to 2,100 fps.
Have any suggestions on where to find what I am looking for?
