Hi Guy,
I have been searching this site for a couple of hours. I apologize if this has been answered some where else.
I have the Lyman 452374 225gn Mold and a LEE TL356-124-2R 124gn RN.
'Casting up a storm and loading .45's and 9's and shooting around 500 rounds of the .45ACP and about 100 9's. No noticeable flaws grouping pretty good at 25yd and excellent (for me ) benching the guns. no case deformities, primer flattening, or case splits
Ok here where I came up with a concern. I purchased 2 digital scale and retired my manual powder scale due to eyes and fed up with it getting out of wack, I have gotten to the point of tracking and checking my reloads since building a pistol range and want to get back into shooting matches by spring. So I started checking my boolits on the .45 and it seems that I am throwing anywhere from 211gns to 228gn. Then checked my 9mm mold and it is throwing 108-118gn suppose to be 124gns boolits. This is using linotype and or WW. I even pulled out some pure lead I had for making 58cal minnie balls and still don't get correct weight. Scales have been verified with certified weights. I have over the last few days been adding a little WW to Linotype this started me up to between 222gn to 226gns an the average, straight linotype was low as is the WW's.
I have both quenched and air cool my castings and no real difference. So should I quit checking the grain weight of rounds, and keep using them as 225gn for the .45 and 124gn for the 9mm?
I flux with Paraffin, lube, and solder flux. I have no thermometer, but will be getting one, have adjusted the temp range up and down on pot. I have no Zinc WW they were removed in first melting of WW. I get no wrinkles after first two cast (either mold) and when a round gets frosty I switch and mold the other caliber.
I am really curious now that I have checked the grains of cast rounds. I have checked my other bullets that are commercial, FMJ and HP Hornady, Sierra, and some Sierra Lead rounds and they are on the money. A couple of tenths plus or minus wouldn't concern me even one grain wouldn't concern me but we are talking upwards of 10 grain differences here.
So am I missing something here or getting paranoid? I load at specification out of 4 manuals now, I have two Sierra manuals, and the last two (48 & 48) Lyman manuals and I have as of yet to bump any pressures.
Thanks an sorry a little rambling but been reading this screen all day and want to give as much information as possible to what I have been doing and doing. I am not loading anymore rounds till I figure out why the differences.
