I have 1000 55gr Super Roos I'm about to start using in my 223. So this will be a change of bullet. Currently getting about 0.7moa with the old 55gr soft points I'm using. (very mild load) This is strictly for hunting usually pretty sensible distances, say out to 170 yards.
Long story short I have lost about 70-80 S&B cases I have used in the past and now have a mix of S&B, Winchester and ADI. All sorted into brands. About 60 S&B and about 40 of Win & ADI. I will be keeping them sorted.
Ill load a few test rounds tomorrow to find a decent load/group when I get a chance to test them.
I have no intention in chasing velocity. The first load I get shoots good groups will do me, so I expect lowish pressures. (S&B Cases)
Now the question. If I develop a load using one brand, with S&B cases is there likely to be a significant difference in accuracy if I use the same load in the others?
Please don't tell me to test all of them. Just wondering what peoples experience has been & what to expect.

My load is 27 grains of 2208 and 55 Rooload in the Win and ADI cases. You cannot get 27 grains of 2208 into the S&B cases without seriously compressed loads. To match the velocity and accuracy the S&B cases are loaded one full grain less at 26.

I recently changed brass in my 357 from Fed to Geco and found it made bugger all difference as I chose the low node and which was 0.6gr lower from the high node. If your chasing out right speed and accuracy then thats a different story.

Id be surprised if you found much more then 0.1 gr diff in case capacity with diff brand cases with the 223

Bill is talking about case capacity. Lazarus is about case weight.

Like I said I've only been loading for a few years so the things I don't know far outnumber those I do.
They can't be bigger in the outside dimensions or they wouldn't chamber so heavier cases should have slightly thicker walls and consequently a smaller internal capacity. Or am I missing something obvious, wouldn't be the first time.
Now that's just my theory, I know many things can be counter-intuitive

It would be interesting to see how parallel loads performed, ie same powder weight and seating depth in the heavier S&B compared to Win or ADI.
