Using different brass for the same loads?

Post by NukeBOMB88 » 13 Feb 2014, 2:00 pm

Hey guys I'm new to the forum and reloading so go easy on me.

I was just wondering if using different brands of brass for the same load can have can effect on accuracy ?
I'm not looking for MOA accuracy , its only use will be for fox eradication on my property.

Thanks,

He's new! Get him! :lol:

j/k, welcome to the forum mate.

Short answer is yes, it can.

Brass wall thickness can be a little different between different brass. Thicker walls = less internal capacity = a little more velocity from your loads. And vice versa.

That's just in general though, the difference could be slight, or could be nothing at all.

If your hunting it probably won't mean anything to you.

Changing might alter your groups a little, or change your point of impact, or do not much of anything.

In any case, it's not like if you're shooting 0.5 MOA with your Winchester brass you you switch to Remington it starts shooting 10 MOA... For what you wan't to do it will be fine.

If you're interested in some reading, you'll see that a lot of the F-Class boys batch their brass by weight and measure the internal capacity and all this business, but that's serious long range stuff.

Busting bunnies or foxes and 100 or 200 metres, shouldn't be a worry.

A slight increase to your group sizes could be expected, for foxes though no big deal.

You can still expect MOA if you've got an accurate rifle with a good load worked up.

I shoot mostly Winchester brass but have a bit of Remington and a few Federal in the mix.

With my 7mm-08 I'm consistently getting sub 0.5" groups with mixed brass.

If you are loading at the hot end of the scale the change in capacity may be enough to spike your pressure up sky high.

My old man had this happen recently a load that was safe in one brand of cases started to seriously flatten primers and leave cratering in another brand of brass he decided to use because it was laying around.

Funny a the difference little things can make.

Obviously there is going to be a margin of error in manufacturing... Everything can't be absolutely perfect.

Being able to stay within the 'safe' data range and still be flattening primers isn't encouraging though :(

A little less margin of error wouldn't go astray between the brands.
