DrMike":2nhb0hvw said:Surveyor,
First off, welcome to the forum. Unfortunately, the excellent .307 never captured the imagination of the shooting public. It is an excellent cartridge chambered in a classic rifle. There is data available, but it is somewhat limited. Scotty has offered to look up in his books, and I'm certain anyone here would be pleased to provide data if you tell us what bullet you want to use and perhaps the powders you have available.

I am looking to see if anyone has used the 170 gr. Nosler Partition in the 307WIn. I developed a load for the 170 gr boat tail soft point that Nosler made years ago for the 3030. The load data is 40 grains of WW748 powder with a Winchester LR primer. I get three quarter inch grouping at 100yds. I am now down to my last seven rounds of that bullet and working on the 170gr Partition. I tried using the same data. My grouping are no better than four inches, which is terrible. Hopefully we can come up with something. Maybe Nosler can address this problem with some testing. Thanks again

You are using your 30-30 data in teh .307...or did I misread that?
But sorry, no experience using WW748.
If I were to use the 170 PT, I would likely start with Varget or RL15

Wow! That really would make that 307 and 170gr PT rock! Scotty
