Need load for cast bullet in .223

[Single Shot]

Hi all,

Newbie to the site. I have an old IDEAL bullet mold in .224 It cast a 50 grain bullet similar in shape to a Hornady V-Max but uses a gas check.

I am using clip on wheel weights as an alloy source. If need be , I can heat treat to a BHN of about 30.

I have a NEF VARMINT bull barrel in .223 that I would like to use this bullet in.

Any suggested loads would be helpful. I may shoot this bullet without a gas check to get a "Boat Tail" effect.

Whats your opinion, and suggestion?

Thanks.
