I got a very helpful reply from @Hoser on my .222 question. Trying again with another cartridge.

I have an M77 Mark II - K77RVT (VBZ) chambered in .243 Rem, manufactured in 1997, with an old Weaver 8 60-B scope attached to it. That's an old Weaver scope, but it's functional. I'd like to load up some ammunition and give it a try at distance. It will either be a waste of time or it won't.

I have not yet measured the twist by hand and will have to do so after the kids are in bed tonight. I thought it was a 1:10, but google is giving me 3 answers; 1:9, 1:9.125, and 1:10. I am reasonably sure the 1:9 & 1/8 twist is a Remington thing and not relevant for my Ruger. It is Model 07886.

It's this rifle:

Based on twist I think I am looking at using shorter bullets, I don't know that a 1:10 will properly stabilize longer match-grade bullets (if they'll even chamber). I don't know a lot about 6mm bullets, but I suppose most anything from 70 to 95 grains would probably shoot okay.

I understand I'm limited based on equipment, but it's paid for and gives me something to mess with. Suggestions on bullets/loading for longer range shooting in this old rifle?

Thanks

I assume you have a 243 WIN, and not the 6mm Remington.

I have no experience loading that round, but I would say that you are often surprised at what works well in your gun. Grab a smaller pack of a bullet and try it out if you have something in mind. In other cartridges I have found that what you may expect to perform well doesn?t and what does may be out of the sweet spot that people tell you is there for that twist.

That's part of the beauty of loading your own.
