I did a little experiment today with my 243 with a small handful of range pick up Hornady 7mm08 brass. I paper clip checked them for head separation issues and found none. So I ran them through my 243 FL die and loaded them up.
A mix of old CCI 200 and Rem 9 1/2 primers was used.
The dial on my Redding BR30 measure was set to where the last part of a pound of IMR 4350 was throwing 42 grains on average. The cases were filled with thrown charges at that setting. Don't worry, 42 grains was already known to be safe.
Some fifty year old 100 grain Sierras were seated to SAAMI max length.
I shot six rounds at 200 yards, and they went into a 3" group. So that's about 1.5 MOA for a six round group. Not too shabby given the haphazard load preparation.
Using holdover, I shot four rounds on a 300 yard gong, and the palm of my hand covered those.
Like I mentioned earlier, with actual load tuning involved, you can get a good 243 ready for deer season in one loading and shooting session. Heck, even with my mix and match stuff today any deer inside 300 yards or so would have easily been in mortal danger. Good to know. Thanks for sharing. BTW, I enjoy reading your posts. I'm an engineer, so I love it when rifle loonies the talked nerdy.
Don't speculate when you don't know, and don't second guess when you do.

RL15 works great in my Sav Mod12 with 70gr bullets, and RL17
puts 105A-max's into 1/4" groups. Tried RL17 with 70gr bullets,
but both velocity and accuracy were disappointing.

I had pretty good success on the first time out. 4 different charges of Varget combined with the 70 grain ballistic tip gave sub 1" groups at 100 yard. Also, 41.0 grs of H4350 under the 95 grain ballistic tip resulted in .75" groups.
My question now, what charge of H4350 are you guys finding to be max with the 95 grain ballistic tip? I loaded up to 42.0 grains and no sign of issue. Although, accuracy dropped off at both 41.5 & 42.0 grains.
I had a snafu with my chrono, so I was unable to collect velocity data on this session.
