This might be a dumb question but would i use the same load data as 240 gr swc if i can not find any? It is for a 44 mag super red hawk.

Thanks

I have loaded the 170gr Keith in 357 mag. when I compare it to a 158gr LSWC the 170gr is nose heavy and takes up less case space. My powder charges are very close between the two bullet styles.

240 grain info for 245 grain? If you start on the low end and work up for your Redhawk, you will be fine. Typically a lighter bullet uses more powder, but 5 grains isn't a whole lot of difference.

About 2 per cent.

I am with RC check Lyman #49. Not knowing your expertise with reloading I would hate to see you start to develop bad habits which could harm you or a loved one or even and innocent bystander at the range. It is usually not considered good practice to use loads for a lighter bullet for a heavier bullet. Though within reason it can be acceptable to use loads designed for heavier bullets for lighter bullet loads.

Get the Lyman #49 its well worth the cost!

240 grain info for 245 grain?The thing is, Lyman lists the #429421 Keith SWC at 245 grains when cast from Lyman #2 alloy.

If you cast it from pure lead, it might weigh 250.
If you cast it from Linotype, it might weigh 240.

If it actually does weigh 245 out of the mold and you size and lube it?
It will weigh 250 because of the bullet lube you added.

Bottom line is, load data for cast bullets should be based on the bullet mold design, not the actual weight the mold throws with the alloy you are using.

+/- 5 grains one way or the other matters not at all.
How many driving bands and lube grooves and total bearing surface it has is what matters.
