Painless load development (mine)

[Sponxx]

Gonna work up some loads for the 243, as I run out of 7828
I have 95g BTs and 105 Hornady BTHP
I have 7828SSC, RL17 and AA4350

Where would be a good place to start? I can think of 25 different ways or more to complicate things, but I would rather keep it simple
Load up a pressure "ladder" to find max loads of each powder? Then compare groups at max load per powder?
Or is there a better powder to try?

For the 95gr BT, they shot great at 3000fps, so I would try to get to that speed, is 7828SSC close to plain 7828?
For the 105s I am clueless

is 7828SSC close to plain 7828

The difference is kernel size only. Same compound with different sized powder kernel.

Meaning I could transfer the load pretty closely dropping a bit to accounting for different "batch", and then work up?

Any powder/load recs for the 105 BTHPs?

First time reloading.

Read this thread before and resolved to follow it because why make life hard?

Shot 9 shots yesterday to find where I hit pressure because it’s my first time doing this and was being cautious. Loaded up at what I thought was a good place below max and came back today to zero.

Did two sighters, followed by 93 more shots at 100 yards. Can vouch that this method works. Now I’ve got 104 bullets down the barrel and won’t clean it for its entire life.

Thanks Form for putting the knowledge out there.

Wow that’s a great group! 93 shots!! Well done
