Kevnew to casting
HI,
I had to start casting,as I had no other choice. I really did not want to, but I could not found anyone who made a 570 grain bullet in a .510. I am getting a custom made win86 in 50-110 from MR. Clay and wanted a 570 grain bullet,higher SD .313 with the 570.I sent a 525 grain WFNGC .510 cast performance to Lee to make the same design but in a 570 grain.I will get between 2000-2100fps with the 570 grain bullet as the 525 grain is getting 2150 fps maybe more.My question on the 570 is if someone wants to use one weight bullet for hunting everything,but may want a little expansion on med size game I. E. deer.I have heard that HC bullets can be placed in a tray of water and the top part can be heated with a propane torch this will soften up the tip and create more expansion. I have just started and order the book by Veral Smith to learn more.I would appreciate anyone advice on this as I am just a green horn with casting. Thanks,Kev

KevHI,
ALADIN, thanks for the information you hit another question I am wondering about.I will get a 1:28 twist in my barrel my gunsmith saids it will be better for the heaver HC bullets, if I were to use jacketed bullets and lighter weigh he uses a 1:15 twist. What do you think. Thanks,Kev

aladinOr for that kind of money you could get a Mos custom mold lathe cut to exactly the dimensions you want utilizing the alloy you use.
The David Mos mold is probably the top custom mold made today.

Martin@HinKev:
Like to react to this,first you have a 86 build, I like the 86 I have one in 45/70 it is a rifle meaning it has the crescent butt plate and this rifle loaded to max has a stiff recoil.
Now I am not recoil sensitive afterall I shoot a 50-90 -338/378-416R and a 500As but yesterday I shot my 500AS with a 550 gr bullet at 1950 Ft/s the gun weighs 10.5 LBS has a brake and kicks hard (read very) the point is before you go out and buy a custom mould I would advise to size the 500 gr Lee bullet down to .511" and try it first.
I am sure if you get this bullet up to 2000 Ft/s in the steel buttplated 86 you will find it more than enough.
The twist:my 50-90 has a 1:36 and has a hard time with bullets over 500 gr the 500 has a 1:18 twist and has a hard time with the 750 A max but does just fine with 550'S.
Hope this helps
Regards Martin

KevHI,
I talk to my gunsmith today and the twist will be 1:26. I also will have a pac pad on a custom made synthetic stock to help with recoil. I should slug the barrel to get the best size for a mold, but I do not know to much about slugging barrels? Thanks,Kev

waksupiJust as a side point, I shot some faster loads in my 86, about 1900 fps, with 500gr. bullets. The magazine backed out of the action from the recoil.

KevHI,
Paul H, I did send them a bullet type that I liked, but I have not paid for any mold so I will look at other mold makes and go with the best one, thank you for your suggestion. Kev
