Thank you for your reply.
The reason for the same cases-primer-powder and charge was to eliminate variables.
The only thing different between the 2 loads was the bullet. 50 V Max vs 50 Nosler Flat base.

Hi Soup. I didn't see this thread again, until now. Someone brought it back to the top. Maybe you have a good load figured out by now?
As for "saving" components, generally you should work up a load for each bullet. Especially in a rifle that is known to have accuracy issues. As in the Ruger #1. However, it sounds like you had Penrod do some work to yours, so that may be a non issue.
When I read your OP, I gather that you are alright with the accuracy you attained from the one bullet, but it was 2" off and you didn't want to adjust your sights/scope? If you are alright with the accuracy you are getting, go with it. Just be sure to know that if you are going to shoot that bullet/load at distance it's going to be off by a fair amount. At 400 yards, it's going to be off a minimum of 8 inches. That's before any shooter error and wind is thrown into the mix.
Like I said before though, Id work up a good load with each bullet you want to use. When switching to a different bullet, re-zero your scope. That can be done with 1 shot, if you don't want to waste components.
This accuracy stuff is always fun to discuss, but it's ultimately you that needs to be happy with it. If 3 shots into less than an inch works for you, go with it. Like I've said many times before, I generally use 5 shot groups when working up loads, 10 shot groups to confirm a load, and when that is done, you can shoot all the 3 shot groups you want. Because you then know the load is viable and you will know (not guess) how consistent it is.
You are working with a 22-250 and a 50 gr v-max, so lets look at something that explains how I generally work up a load. I'll use my buddies 22-250 as an example. With these pics, you can see how much I increase powder charge. In the 22-250, I'll generally increase charge weight by 1/2 grain increments:
Started at 34 grains:
34.5 grains:
35 grains:
35.5 grains:
We did more testing and found out that the 35gr charge wt load was the most consistent. Also as these pics show.
Now, my Tikka Varmint model likes a slightly stiffer load of 36 grains of the same powder with the 50gr v-max. Also notice the OAL is different too. I always run .020" off the lands with this bullet, in all of my rifles. However, you'll see in the last picture that the 50gr v-max is not particular when it comes to how far off the lands you run them:
The same Tikka, testing a load I developed in my Steven's 200:
10 shot groups^^
Proof that some rifles are just less finicky than others.
When you say you wanted to "eliminate variables", that is what you want when you develop a load. Some variables you need to know: Know your seating depth, and how far off the lands you are running, and since every bullet make produces a different pressure curve, you should really be starting at the start. Hence, safely and properly working up a load.
