Bought a 311284 mold from Midway a few months ago, before I started reading this forum (or I would have known better)!
First outing yesterday with said bullet in 2 of my 30-06 Springfields, results were beyond terrible. I could have done better using a 2'' .38, blindfolded, and left handed at 100 yards. Bullets went everywhere, couldn't begin to get a group even at 50 yards.
Load was as follows: 311284 approx 214 grains, as cast, .309-.3095 body, .299 nose measured w a micrometer (not a caliper).
LC 69 brass, Win primers, 19.0 gr 2400, no filler, OAL 3.252", bullets seated out to lower edge of first driving band based on the throat of my vintage '03 target rifle. There was no evidence of leading.
After that dismal showing, I loaded the '03 target rifle with 168 Sierra mk's and 43.0 gr of 3031. Put 10 shots into a measured 1.3" at 100 (iron sights) and my 66 year old eyes. It's not the rifle.
I suspect I have one of the undersize Lyman molds mentioned in some older threads. IS THERE A SOURCE OUT THERE THAT CAN FIX THIS MOLD AND BUMP THE AS CAST SIZE UP TO .310-.311 body and .301 nose??
I have a 7.5 Swiss. Should I try them in it? Really don't know how their barrels size out in bore and grooves.
Or should I just put this up for sale on ebay and be done with it!
Help appreciated. Thanks!
