1st time .257 Roberts w/ 100AB

[flyfish]

Well, I've been meaning to do this all summer but I'm just getting to it.
I'm going to try some 110AB in my Ruger M77 257.

I had called Nosler and they said to use the reloading data for the 115 gr BT. I have loaded for the 115BT before and that load in my gun was a tack driver. So tonight after work I'm going to give them a try. The load is 33.0 grains of IMR4895. I also have some IMR4350 that I may try too. I was think of using about 37.5 grains of IMR4350, does that sound reasonable? I don't have the current Nolser reaoding manual with the 110AB loading data.

Any help or suggestions is always appreciated.

Go to http://www.nosler.com and look for their "ballistics room" under "information." You'll find that they've got some great data posted, including data for your .257 Roberts.

Here's a link to the .257 Roberts page:

Good luck! :grin:

I had loaded 5 rounds and shot them yesterday a@ 100yds. The first shot was from a cold/clean barre and was off to the left a bit. The next two shots were close to each other. I shot two more rounds. One joined the other two holes making it so I could cover three shots with a dime ( or just about) the last shot well, lets say the jerk behind the trigger made it not so good :roll:
The load was 33grs of 4895. I may try going to 33.5 and 34., just to see if the group improves.
