The most important part about shooting a revolver is learning how to be accurate with it in double action mode.
I'm going to disagree with this statement, only because is it phrased as an absolute. Defensive/combat style shooting isn't the only way to shoot, and for a lot of us, isn't the only thing, or the most important thing.
About half my revolvers are single actions. Not going to be shooting any of them DA.
To me, the most important thing is being on target, and on time. However you get there.
If DA shooting is important to you, then its important. I just don't think it is the single most important thing about shooting a revolver.
I saw mentioned to fire a box of each. Do you think that twelve rounds per revolver will be enough to test or should I suck it up and go for a box of each per revolver?
If you are looking to see what a given load does from a specific gun, you need to shoot enough rounds that you can be reasonable sure that your performance shooting is not a major factor.
Shooting from a rest, having other shooters (of known, proven ablility) shoot a few rounds, to compare against yours, these things help reduce the "you" factor, and give a clearer picture of what the gun and ammo will do. That is PART of the process. The other part is seeing what YOU can do with the gun and ammo combination. The difference between the two tells you which part of the combination needs improvement (if any).
Lets look at a couple of examples, for illustration...
If you shoot from a rest and get a 3" group, but unrested, you can only get a 6" group, then what needs work is you.
If you get a decent group, but its a foot low, and left, but your buddy gets the same size group, dead center of the target, its you.
If load A shoots a foot low and left, and load B is dead on, its not you, its the gun & ammo
You buy ammo a box at a time, split it up between different guns however you choose, Just shoot enough from each one that you can tell if it is the gun, the ammo, or you that makes the most difference in the accuracy.'
one gun a friend had shot wonderfully with 158gr .38 Special. Spot on at about 25feet. Couldn't hardly miss, even very small things. Same gun, ANY other ammo, shot to a different place, and group size. 125gr .357s shot a foot low and a foot left, in the hands of multiple shooters.
That kind of performance is rather common. That amount of difference is extreme, and uncommon, but can happen.
If you have a gun that throws a certain load into a really odd place, a couple of cylinders worth is usually plenty to show that, and shooting a whole box "low and left" (or where ever) is just a waste.
I don't know the MBI brand, so no comment on that. WWB ammo is their bargain stuff. Expect it to work, but don't expect more. If you get more, say thanks to the shooting gods.
Before stocking up on a quantity of ammo, I think you would be better off doing a bit of testing first.
Which is better, cheapest ammo that shoots, say 5" group in your guns in your hands, or more expensive that shoots 3" under the same conditions? And how much more expensive it is, vs what you get, and what you want plays a part, too.
if you get better results from ammo that costs $1 more per box, is it worth it? If its $3 a box, is that worth it?
Shoot enough different loads (ammo brands, and bullet weights) to see if you DO get a significant difference in results. Then, if you do (and you may not get a significant difference), then you calculate if the difference is worth the cost.
And of course, with the shortages still with us, what you can actually get plays a big part in it, too.
Good Luck!
