John, I found the 205 gr data but I don't have any H414 and don't want to buy any just to try that bullet. I tried some loads with IMR4227 that weren't impressive. I made these for my .303 British but they all keyholed, so I thought I would try them in the Savage. I guess the .303 Savage & 30-30 don't shoot heavy bullets well or there would be data available. I will just melt them down again and mold something else. Thanks everyone for the advice.
As with any cast bullet you intend to use in any firearm, square one is to slug & determine the bore daimeter. With a calibre of this size, I've had good success sizing the bullets 0.001" greater than the bore diameter. With
some of the 'stuff' 44cal and larger, I'll go as much as 0.002" over.
For the .303 Savage, some sources of info indicate the use of 0.308" diameter bullets and the next 'suggests' 0.311". While the Lyman 1st Edition Cast Bullet Handbook states " use same bullets & charges as listed for the .30-30 Winchester", they
also suggest a cast bullet diameter of 0.311". In Pet Loads, Ken Waters also states "0.311" cast bullets are vastly superior to 0.308". Again, to start with, I would suggest determine your bore diameter. Oh, in the back of Lyman 1st edition cast book there is a cartridge chart and they show three
suggested cast bullets;
# 311291........170gr
# 311466........150gr
# 311413........165gr
In Pet Loads, Ken Waters makes the following statement;
Among the cast bullet loads which performed the best were two:
(A) Lyman # 311291 with 17grs of IMR-4227 with mild ignition provided by Winchester # 111 Large Pistol primres -- a combination that would shoot five shots into 1/16 over 1" with four shots in 3/4"
(B) Lyman # 311375 & 19grs of IMR-4198, fired by Remington #9 1/2 primers, averaging 2" to 3" for five shots, and approximately 1 5/8" for four. Anyway, going to a more conventional bullet weight for your .303 Savage might be the route to take.
Before you go to melting down the 217gr bullets you have, I'd suggest making contact with hs4570 for input. He's done some similar required experimenting with unlisted bullets for some different calibres. Hope this helps you out a bit.
