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.
