I found another great load for the .257 roberts. The bullet is a nosler 120 grain partition. The powder is RL-22.
The max load from the Aliant web site is 46.2 grains and it shows a 48000 Cup and nearly 3000 , fps from a 24 inch tube.
My load is a bit hotter ill let you decide how hot to shoot in your rifle.
I was very happy to see the .40 and .60 inch groups I got off the bench at 100 yards.
This from a 20 inch featherweight ruger.
I hope my short tube will not cost me too much speed I am hoping for somthing over 2800, we will see !
It aught to thump any mule deer walking at 300 yards and prbobly a caribu too !

I just happen to have some R22. Maybe when I start working loads for my .257AI I will look into this one. With added room and a 26 inch tube I should get 3000 with no problem I would think.

With DP 85 it would be a done deal. roger

TJ how about PM'ing me with your RL22 load and 120NP's? I have had little luck getting the 120's to shoot in my Ruger Ultralight. I am trying 115's now.
Post modified: My Alliant book shows 44 grains as the max load for 120 gr. bulets and RL22.
Modified again!: The website does say 46.5 for + P loads. I would still be interestd in your load.

John Barsness's 1st "loads that works" had 48.5gr of rl 22 @ 2,950 fps(?) I tried the load in a 24" m700 clasic & got in the upper dend of the 2,700 fps with so-so accuracy. Hope you have better lunk than I did.

Only 2700 ?
Well I hope I do a little better than that. I got about equal accuracy in the same ruifle with the same bullet and using IMR-4350. I got 2720 fps.
That aint a bad load mind you but I want 2800 or more if I can get it !

There ain't no bad loads for the Roberts, It is always fun to shoot and gets better!

TJ what was your IMR 4350 load? You can PM me if you want.
Thanks, Peter.

I've been loading 48 or 50 grains of RL22 behind the 120 Hornady HP for years....48 gr in Federal cases & 50 gr in W-W +P brass....Outstanding accuracy and approaches 3050 fps out of my 24" pre 64s....

Thanks wood chick !
I just bought a new can of RL-22 and hope to squeez off a few rounds this weekend. I,ll squirt a couple over the chroney with 48.5 grains and if it prooves a little slower than I like I will go up a half grain and see where I am then ...tj3006
