1000is,
I bought a Lyman 225438 during the peak of the rimfire shortage, and it worked very well in my rifles. Cast from clip-on wheelweights they weighed 43.5 grains, and would put 5 into an inch or less at 50 yards with these loads:
.22 Hornet--5.0 A5744, 1080 fps
.223 Remington--4.0 Blue Dot, 1187 fps
225438 is a gas-check mold, but in my rifles the bullets shot best unsized and without gas-checks. I just cast 'em, rolled 'em around in Lee Alox and loaded them a day later. Pretty cheap and easy way to shoot. The primers in the Hornet loads were CCI 500's, and in the .223's Rem. 7-1/2's.
