257 TCU Load Data

[JCMILLER58]

Does anybody load for the 257 TCU? Load data is scarce as hens teeth. The 25-45 Sharps is the same basic round. Lots of info for the 6, 6.5 and 7 TCU but I cant find anything published for the 25.

You can use the same load data as the 25/45, it is very close, only the TCU has a 40 degree shoulder adding a minimal amount of added case capacity. The .25 TCU & .30 TCU are far less popular than the 6, 6.5 & 7 TCU.

I purchased two boxes of 22/45 from Sharps. I have not shot them yet so at least I will have some factory loadings to compare my hand loads to.

I did locate this info. I have two 8 pound jugs of H335 so I will be starting with that.
