Hey all, been a while since i've posted here but i've come to a stand-still with my handloading and i knew this is the place to go. To make a long story short, i found the pet load for my current rig (Remington 700 AAC-SD in a B&C Light Tactical stock) a few months back. I was loading brand new Lapua brass as the following:
Lapua Brass (FL sized)
42gr Varget
Fed 210m Primer
Hornady AMAX 178gr
Set to 2.800" COAL
My first groups after finding this load were consistent .5moa at 100 yards, more than fine in my book. After sticking with this, i cleaned/neck sized all my brass and reloaded. I noticed after reloading the first time i had 4-5 fliers opening my groups to about 1.5" here and there. I figured maybe my shooting was off that day, wind etc and didn't care too much.
My biggest problem was last thursday at the the range. This brass is on it's 3rd reload by then. Same recipe, same COAL, but not my groups were opened to 1.5" occasionally a really wicked flier here and there. Sometimes i'd be lucky and pull a nice 1" group, but average was 1.5-2"....
My question is could it be because i'm neck sizing instead of full sizing? Or maybe i need to anneal the necks? Is my brass volume changed after it's been fired? I've never used once, twice or three times fired brass before (all from one rifle obviously). Any ideas as to what my deal could be???
