Loading for the 9.3x74R, Quick Load Request.

[Oldtrader3]

Could somebody please run QL for me on the 286 Nosler Partition for the 9.3x76R with IMR powders at 50K PSI? I took my Number One Ruger with the 22 inch barrel to the range today and started the sight in process at 25 yards. I was there anyhow with a couple of rimfire rifles getting them sighted in. So I figured I would start shooting some loads, just to get acquainted.

The Number One 9.3x76R is a thumper in a 7-1/4 pound rifle with only a 1.5-5x20 Leupold VX3 on it, to bring it to about 8 pounds even. I shot loads including the 270 gr Speer, 286 Norma SP and Partition 286 gr, all at about 2400 fps. I have used three powders so far, including H-380, IMR 4064 and 4350. The IMR 4350 and the H-380 both shot very small groups (one hole at 25 yards) and the IMR 4064 with the Partition shot poorly. However this was only a beauty contest and not a serious 100 yard group test.

I also need to add some 250 gr Accubonds to the mix and see how they shoot at 100 yards. The 286 grain bullets let you know it when you pull the trigger in that light rifle! However, I have just begun load development and testing.

Charlie, I remember Scotty and Aleena discussing this somewhere, only it seems like they were discussing Woodleigh and Norma Oryx bullets, hopefully one of them or both of them will see your post. That is a sweet old caliber Charlie and a very nice set up. Best of luck working up your loads

Charlie, I remember Scotty and Aleena discussing this somewhere, only it seems like they were discussing Woodleigh and Norma Oryx bullets, hopefully one of them or both of them will see your post. That is a sweet old caliber Charlie and a very nice set up. Best of luck working up your loads

Sean, I will look for those conversations, thanks for the feedback on the caliber, so far so good with loading and shooting.

DrMike, thank you very much for the QL data on the 9.3x74R. I will go through it over the next couple of days and see how it compares to what I am doing so far with loading.
