Load development is going fairly slowly for "deer" loads in the .257 Roberts. The only loading at full power or "in stock" at home is my "practice" load a 100 Hornady Sp at 3075 fps from a 22" tube, this one is MOA. Anybody shot deer with these bullets?

Plenty of antelope at 3300-3400 fps from a Ruger #1 25-06.

All bang-flop.

I shot a couple mule deer with a .257Robt's using the 100gr Hornady SP Interlock at 2950fps. One was fairly close, the other was about 300yds. It's a good "deer" bullet.

Thanks POP, I just didn't want to have to try to get to the range before the opener Saturday to try to test out my TSX load after a powder lot switch or try to finish up the 100 partition load and have to face the boss as her to do list got slipped

The mulie in my avitar was taken with a single shot from a 257 Roberts and a 100 grain interlock.

So nothing fancy just solid plain jane kills and mushrooms? I can live very well with that! Nice mulie by the way. I saw a ton of nice one around O'Neill weekend before last. It'll just be a couple whitetail does over here.
