Remington 783 .243 hand loads?

[Brapp891]

Just acquired this thing and looking for any in-site on what works well for hand loads I have a box of 90gr Speer hot cores I’d like to get a rough idea what powder and charge it likes to work off of instead of trying at 8 powders I have for it… thanks!

I second this! I also have a 243 that I am going to home feed. Mine will get 100 grain Sierra Gamechangers.

4350 or 4831 will do you fine, any abbreviation up front.

I've used H414/W760 forever with 85 grainers...Meters real nice and gives great velocity and accuracy.

Have found most new book loads are very conservative old books used 2-3 grains more than they publish these days and I concur with the old data.

You'll want to try the 90gr Sierra TGK unless your 243 has a 1:8 or faster twist rate

It's 1 : 9.25

More 4831 and don’t load them so long. Same advice I gave you over text last week

Not reloads, but 100 grain Federal factory stuff works great. 1/2 MOA in my wife's gun.
A little work to free float the barrel and stiffen the forearm of the stock to avoid contact will go a long way to improving accuracy (I've done that to her gun).
