Fired about 14 rounds of the Remington 180 factory stuff and my first three test loads.  So I have now put 23 rounds through the old gun.
The 180 gr Remingtons ranged from 2323 - 2470 ft. sec.  Most were in the 2390-2425 range.  They seemed to be more or less POA at 50 and 100 yards.  Once I got settled down and stopped looking at the gun and the cases every time I tried a little harder to aim properly and the last four rounds were all in the ten ring @ 100.
I also fired my Hornady 220 RN loads I made up with once fired brass.  I used 38.0 grs of IMR 4350 and they ran at 1780/ 1794/ 1817 ft/ sec.  They impacted about 1-1/2" low at 50 yards but I was still spending more time checking things than aiming so that is just a rough idea of what they were doing.  I did not have enough to test at 100 yards.  They seemed to be light loads and less hot than the Remington.  I will try 39.0 grs of IMR 4350 next time and see how much the POI comes up.  All cases looked fine but the fist time Remington loads do slightly distort the base of the case wall.  It appears to be more of a conforming the the wall than anything else.  The reloads using the once fired Remington cases did not exhibit any further changes.

BTW:  how many reloads are you guys getting out of the Remington cases since that is all that is around now?
