Thanks for the information, as usual I'm over thinking things.

I went to pick up the supplies needed according to my Barnes manual. I got Remington 9 1/2 primers, the Barnes 80 gr. TTSX and was supposed to get Hogdons Superformance powder. However Bass Pro was out, so I tried to get H4350 and they were out of that too. I settled on RL17, anybody have experienced with RL17 and the 243? I have a starting load of 43 grains. Is IMR4350 the same as H4350?

I stand corrected starting load of 38.9 max load of 43.3. do you actually go up in .1 increments until you find an accurate load, or do you go up in say .5 increments until you find one that looks good and adjust up and down to see how it reacts?

My advise for what IRS worth: start at the lower range of suggested load. Look for signs of pressure. Work up in (1) grain increments. 1/10 is way too small in the beginning and maybe too small for all but the most precise competitor. With that Barnes back way off the rifling. 50-70 thousandths. Shoot and see how they do at the same COL. Chances are you will find something good quickly. Then tweak from there. Might not even have to mess much.

Why so far off rifling with the TTSX?

My Barnes manual says .050 minimum I think. I need to review it. I prepped 20 cases last night once fired Nosler brass resized, trimmed and primed. I think it has something to do them being all copper which causes and increase in chamber pressure due to higher friction and less compression. It is also the reason they have the relief bands on them.
