Loads needed: 243, RL17, 105gr hybs, 115gr dtacs

Hello Gents,

I finally got my barreled action back from my gunsmith. Here are the specs:
Bartlein 1-7.5" twist 5R 28" length
Chambered in standard 243win
Throated for 115 DTACs

I have some RL17 powder, 105gr Berger hybrids, 115gr bn coated DTACs, and 215m primers to start with.

I'm just looking for some load specs to start with and some of your experiences with these components.

Thank you.

My 115g load is RL25 46.5g Nosler case Federal match primer 2995 fps and pretty accurate.

According to QL, I'd start at about 37Gr's of RL-17 with the 105 Hyrbids and work up in .3 to .5 gr increments to approx. 39.5 Gr's keeping a close eye for signs of pressure. Pressure may show up a little sooner with the 7.5" twist but starting at 17Gr's you should get into the ballpark rather quickly. Good luck, let us know how it works out.
