Can someone send me a photo from the Hornady book with load data for 243 Win 100gr?

I’m trying to work up a mild load for a friend’s kid using 100gr Interlocks.

I’ve already got references from Hodgdon and Nosler, and things are all over the place. Also I can’t even get close to reconciling it with Quick Load.

Also any suggestions for a 2550-2600 fps MV would be helpful. I know I can get there with H4895 with some work up, but I’ve only got less than a pound left and I’m using that lot for my son’s 270 and 30-30 loads.

I’m hoping I can get to that MV range with H4350 or IMR-4064, as I have a ton of those powders - but don’t want to be below the minimum recommended charge weight.

My book shows low end values as
IMR 4064 = 31g @ 2600 fps.
H4350 = 37.4g @ 2700 fps.

It doesn't list any of the other powders on your list.

IMR 4064 is wonderful in the 243 in that weight range of bullet. I would think it is one of the most highly regarded powders for that application. Should be able to load a ton of options that will get you at or close to the MV and recoil that you are looking for.

My book agrees with jrock's numbers but does show 29.4gr of IMR4064 @ 2500fps before 31.0gr @ 2600fps.

Ok. I’m presuming it’s a 1:10, like 95% of 243’s. Could be even more twist than that. I’m going to get the gun from him this weekend.
