I cast up some 200gr LSWCs from my H&G #68 4 cavity mold awhile back. (I owe someone some of them too, this week!)
I shot them the same day I cast them and noticed I had some leading in firearms I have never had any in before. I did make them a tad harder than normal but not real hard, around 15BHN or so. The only thing I forgot was that they take a while to get there. After letting them sit for a couple of weeks and shooting them today, I was back to the "leading free" zone!
What I wanted to do was get this bullet into the 800fps area. The load I shot today was just under that though.
I did find an interesting item though. The Speer #8 is a "WEENY BOOK" when it comes to this bullet with SR7625.
Current data from the Hodgdon site lists 6.2gr as a starting load and the Speer #8 lists 6.0gr as a MAXIMUM LOAD! What a 'WEENY" manual!
The maximum from Hodgdon has 6.9gr with a velocity of 952fps. Their 6.2gr data says 836fps and that would be pretty close to what I would think I would get had I used that load.
What I did instead was used the maximum load from the Speer #8 for this bullet/powder combination, here are my results:
From my M625JM
Low 739.1fps
High 802fps
Avg 766.2fps
ES 63.25fps
SD 31.25fps
From my PT1911
Low 761.7fps
High 800.2fps
Avg 781.1fps
ES 38.5fps
SD 15.05fps
I have always gotten better numbers from the Taurus. Accuracy in each firearm though was superb. I didn't put them on paper, no need to as I am not planning on using this load for anything in the future. I just had some free time and this partial can of SR7625 sitting around and thought I would head to the range!
You want to know how I know they were accurate? I used a "fun" accuracy criteria, "minute of plastic bottle" accurate.
My wife gets me "Powerade Zero" for my lunch everyday. I was wondering what good those bottles would be good for, so I found a use for them! Now, these bullets were accurate enough from each firearm to put a second hit on a bottle as it was still in the air. Good enough!
They were a pretty clean load too. I think it would really clean up good as the charge weight was increased. I just don't need a 200gr bullet going any faster than this from these firearms.
I haven't had any reports for awhile so I thought I should get busy!
