Ruger no1 7x57

6.5cm, 6.5x55 and a couple of others in that category.

It's a useful powder but hard to come by. If you purchase any, purchase enough so that you have a supply on hand that you can continue to use, after you've developed your initial loads.

A pound at a time is a waste of money/components/time if you can't find anymore.

Is becoming a real thing, these days - sorta like finding a tray of 100 primers and going to "work up" a good loading. Or a single box of 50 or 100 bullets - And then what? Assume 50 grains per loading - that gets you 140 rounds. So, is easy enough to fire off 40 rounds to find a "good load" - after pressure series, testing for accuracy, etc. So a pound of new-to-you powder leaves about 100 rounds worth. For some people, that is a Saturday at the range. For others, is a decade or more worth of hunting - just not much for practice, or for verifying that scope is still sighted in. For decades, I would just go to local store and get more of what I needed - so I bought single trays of primers, one pound bottles of powder - one or two boxes of bullets. I suspect those days are gone?? Certainly the stores, and their inventory, are.
 
Well I went to the shop and no more Staball 6.5 on the shelf or so I got told( they keep there powder in the back and they don’t keep a list of what they have… so you go in and ask one of the kid and hopefully he knows what you are talking about and go to the back and come back with an answer…. Anyway, there are a lot of pros to live up here and the gun shop ain’t one of them lol!
 
I have a Ruger #1AB [22" barrel] chambered in 7x57. It shoots the 140 AB or Partition best.
Powders that have proven out in it are Reloder 17, Norma 204 and MRP, Reloder 19, N560.

OP - From Nosler book - 51.0 of RL-19 and 150 Partitions was the loading that I worked up to in my 1A - was what I used 2004 until 2015. At that time, I could get R-P cases and Fed 210 primers, so is what that loading consisted of. My notes say that I started at 47.0 grains powder, which Nosler indicates was their most accurate loading with RL-19 and those bullets - I went up 0.5 grains per step and monitored velocity on a Shooting Chrony - ended up at 51.0 grains and most every time was a bit over 2,800 fps - Nosler reports getting 2,831 fps with that loading from a 22" Lilja barrel. They used W-W cases and WLR primers. My "development" was done in summer 2004 and I never changed from that loading.
 
No idea yet, I’m waiting on some brass to show up! And plus I have 3 other rifles to work loads for so maybe later lol!
