Re: Stable & Unstable
Well....
Being that your location is in Kalifornia, with the fast approaching deer season opener, coupled with the CRAZY law about lead free ammo in the "California Condor range".....
You went from lead cored bullets to solid copper and retained the same weight bullets. Lead is denser than coppper so your new copper bullets in the same weight as lead are longer, your rifle barrel is not twisted fast enough to shoot the new eco-friendly bullets.
For example; you have a 25-06 and it always shot 117 gr SST's great. You go down to the local wally world to pick up a box of lead free hunting ammo and they are loaded up with some "high speed top of the line gauranteed to kill grizzly bears but not harm a mythical bird with lead poisioning" Barnes copper bullets which are 117 gr. Now they dont shoot for shit, as a matter of fact they are tumbling through the air and entering your target wherever they decide, sideways. That is due to the larger bearing surface of the copper bullets in the same weight as your old leaded bullets.
Solutions: 1) hunt north of Mariposa County (zone D6-north)
2) Rebarrel your rig with a faster twist rate barrel
3) drop down 10-15 grains in the copper bullets and cross your fingers
4) run a bullet with no exposed lead and cross your fingers
5) take up bow hunting
I have been hearing of a lot of inhumane shots (not kills) since everyone south of the mason-dixion line was forced to switch to the lead free ammo.
