thank you Charlie , 🙂 i bought a aluminum 454 round ball mold from Midway for the heck of it , but the accurate i think i will buy the iron ones like you say , now how hot do you get the lead for aluminum pure lead , and how hot for the iron , i heard they are a little different temps ,
i had a guy that cast a lot tell me to clean the mold then use kroil on the aluminum mold -soak it over night , then take a Q tip wipe it out then hit it with the lighter like you said , he said /claimed this works great , he said if they come out wrinkled that the temp would be to cool , if they turn out frosted that, that was caused by to much heat .
i got the shoebox test running again , i had another oring fail again this morning , so i took everything out of the cylinder cleaned it , then i sighted down the cylinder to see how the piston rod lined up , it was off a bit , i had to bend the plates that that the roller piece slides back and forth that holds the lower rod , to get it to alien right , cross my DAM FINGER’S ! this time it works for a while , god i hope ! 🙄May 5, 2011 at 3:39 am #133418
I have never tried Kroil.
My mold I seasoned as I described, and put a little graphite on the sprue plate and top of the mold.
I can open the sprue plate with a gloved hand when at the correct temp, and the bullets fall out most of the time without any tapping with the rawhide mallet.
Watch the cut sprue, it will tell you if your opening it too soon, if it looks like it sheared solid metal your okay, if it starts to look like it is breaking you at the verge of too hot, if your getting lead smear on the bottom of the sprue plate your too hot. There should be some resistance to opening
the sprue plate.
I add lead to the pot when it gets too hot to cool it down and leave a cast bullet and sprue in the mold while the pot heats to temp again for casting.
Remember, any oil on that mold will result in wrinkled bullets for a long time.

re-edited post – i am still trying to get the shoebox to work again , got off the Phone with Tom K going to keep working on this thing, and try to get it going , as Tom is willing to help out with parts or new unit .May 5, 2011 at 5:42 am #133424quote roachcreek:
Charlie those bullets look GREAT ! 😆 😆 good job man ! 😆 you got me all exited to do this ! 😆 i just know it will be worth it because we can make what we want , and need for these gun’sMay 6, 2011 at 8:58 pm #133523
I have to say the trigger on this gun is AWSOME 😉 😆 😆 on a few other threads we had a few members that decided to put Dan’s trigger down before they had ever shot this gun well i have shot it some 400 time’s now , and i can tell you it has shot / trigger pulled perfect , there is no inconsistent rough spots at all , it is just perfect butter smooth even until the gun goes off , it was like this new out of the box ! 😆 PERFECT ! 😆May 9, 2011 at 1:35 am #133620
I did some shooting today , tested out RoachCreek-Charlie’s 45-425b bullets , the gun really liked them a lot 😆May 9, 2011 at 1:43 am #133621
The picture did not come up, how did they do and at what speed?

around 900 3 shots right next to each other , i will try again to post the pic up , the 340’s were almost 1000 fps i cleaned the lube off them , before i shot the 45 425b’s ,May 9, 2011 at 1:53 am #133623
It is not fair comparing your groups to mine, your 8 inches closer to the target. 😆

HA ! HA ! thanks again Charlie , those bullets you made hit like a sledge hammer 😈 😆 😆 BOOM ! ——-BAM !May 9, 2011 at 2:09 am #133625
They don’t seem to like the Lee Alox I guess.

That was shooting them with no lube at all 4200 psi , 50-60 yards , I was tethered to a 44cf tank , god that was fun shooting , i can see now what design of bullet that gun likes , that 408 ,and 340 both shot well , got hit by a hail storm up there and had to put everything in the Yukon quick like 😯 , before i could get my table down the ice /snow was 1 inch thick ! 😯
we had a couple of Army special ops guys up there today , they both shot my gun , and were amazed , these guys were blasting gun nuts i must say , my ear plugs were in the whole dam time , i don’t know how many clips they blasted through 😆 😆 😆 those guys set up targets in all direction then ran around and aggressively , un-loaded clips on all targets , they said they were headed back to afghanistan for more Killing ! one guy showed me 2 hollow point 40 cal bullets opened up like flowers that he said went through some taliban members ! CRAZY ! 😈May 9, 2011 at 4:49 am #133629tofazfouParticipant
YEP, those big bullets of RC’s are keepers for sure. These big bores with their current twist rates really seem to like the 300-400+ gr bullets. Very nice shooting and very nice casting by RC.May 9, 2011 at 5:37 am #133630butcher45Participant
Nice shooting…..whole lotta power behind that accuracy!
Take a good look at that Accurate Molds’ 180grain version of the EPP/UG for a lightweight alternative. Worth a gamble, as the regular 154grain EPP/UG’s appear to work stellar in RoachCreek’s Ranger.May 9, 2011 at 1:15 pm #133636
I am not a gambling man, now there are a lot of people who would disagree with that considering some of lifes adventurers I have been on.
The EPP UG is a nice bullet, but it is a name that is hard to say. 😆
Last night I was getting together an order for Tuesday morning, when I was looking thru the Midway mold section and I saw a 165 grain 452 RF bullet in a double cavity mold for less than $20.00, I already have a RB mold in the cart and I added the RF bullet, anyone ever had experience with that one?
