243 Win. Ammo and loads?

[JDeere]

95gr BT's over IMR4350 shoots lights out in my old model 600. Back in the day before I started reloading it was the Rem 100gr Core Lockts...

It is probably more common with rimfires, but finding a happy place may require trying several factory loads to find the gem. Mine likes the Remington 100 gr. Core Lokt.




37.2 gr IMR 4895 and an 85 gr Barnes TSX shoots pretty well in my 77RSI. (In Ca it is lead-free or bust.)



Good luck finding the one(s) that work best.

Stay safe.
