6MM Creed or 243

[urbanrifleman]

Never had a donut in my match rifle's brass. I have reloaded brass over 6 times and no issues. I only have one .243 barrel now and it's not on the rifle so not worried about it but the .243 is a viable option if he wants to stay with it.

I assure you, you have a donut after 6 firings. The brass has to flow somewhere.

You can short size the neck and let the base grow. That is what I did. But standard resizing will have a donut.

I can assure you I do not. Sorry it's not what you have experienced but no issues at all with my brass.

I like the .243 with a 30* shoulder. a little barrel life, and a little more velocity.

No it doesn't. Ran one for years and still have one in a short action and works fine. Have run 105-115s in it with a short action.

If you running 115's in a short action 243 you reducing your case capacity significantly to cycle through tha magazine, you may as well use the 6MM ARC, plus your using a custom twist. The 115 surely needs a 7.5 or a7 twist to stabilize. You might get away with 100 yards.

No it doesn't what?

Look at what he quoted, he bolded the part he was addressing.

Got it fixed, clearly seating way back into the case reducing power capacity.

No you aren’t. I load in aics mags in a short action and can load them out to 2.870”. No problems and no issues with pushing too far in case. Not every short action is a Rem700 with an internal 5 round mag and limiting to 2.820”. Even the. Notching the feed ramp can be done at home and makes it easy to load longer.
