been out of the reloading game for a while, and I cannot for the life of me find any of my reloading books, i think my dads got them at his place some where. Im trying to find some load data on 77 grain SMK's and CFE223 that i recently picked up. I have written down on my scratch pad that 22.5 grains is the start load, and 24.3 is the max load, with a COL of 2.260. does this sound correct? looking to make some TAC & CFE loads for my SPR testing.
not looking for anyones secret recipe, just looking for the general safe load data. (i do have my TAC data already)

Thanks all.

I found that 24.0gr of CFE under a 77gr SMK shoots quite well and doesn't display any signs of pressure. Shoots well enough I didn't see the need to try the extra .3gr maybe I should give it a try on a 30 round batch and shoot three 10 shot groups.

Look at the Hodgdon reloading page. They have data for the 77gr SMK and CFE223.

I personally did not find any nodes with CFE223 that beat my TAC loads for velocity, SD, and group size in 77gr bullets. I think the burn rate for CFE223 is slower and it pressure spikes faster once you reach the max. That said I didn't load over the published max for hodgdon data. It's possible a good node was past the published max but I don't like pushing those limits much.

I should also add that CFE223 seems to leave a metric-crap ton of greasy carbon in the gun on lighter loads, but zero copper as advertised. :)
