I should have remembered the rule and followed it . But what fun would that be .......
I have been working on cast in a 308 on and off over the last few months & slowly but steadily getting better results until today . Today my 100 yard groups look like my previous 300 yard groups . They were so bad I checked the rifle to make sure nothing had came apart .
I have been using coww's + tin cast NOE 311-180 FN , gc sages .15 copper checks , 35 gr of IMR 4350 , Winchester brass , win Lg rifle primers . Easily getting 2 - 2 1/2 inch groups at 100 yards around a 1/4 sheet of paper groups at 200 , and all on a sheet of notebook paper out to 300 yards . Loaded on a progressive press .
I know many here do much better , but I have been tickled with my meager achievements .
# 1 Well I cast me up a nice bunch of new boolits but I used my 50/50+ tin blend by mistake , not panicking I decided I'd give them a shot because I have already lube sized and checked them .
# 2 I decided to use some sample gas checks on some not perfect cast boolits . Just to see how they would shoot .
# 3 I started in on a batch of once fired 68 RA brass instead of the Winchester cases . I have been playing around with the powder charge and found the 35 gr charge in the Winchester brass was about as fast as I could push without the group's opening up .
Well I decided today I would zero the scope at a 100 yards , and set the caps on zero since I have been playing around at longer ranges trying to get a idea of my drop adjustment . I figured it would be a good time to shoot up some of the culled boolits ..
It didn't work out 10-12 rounds down range had me back in the house checking the rifle to make sure nothing came loose . Now I have to figure out what went wrong .
culled boolits , alloy , gas check , brass & or Powder charge
