Does the type of hull really matter

When going by a reloading receipt does the type of hull you are using really matter?

It is not just kinda important, it is critically important! Depending on the load mix involving selected components: primer, powder, wad, shot weights....the load might be a blooper in one type of hull and a potentially explosive gun destructive load in another type of hull. Stick to proven published loads and buy and use a good powder scale.

Go online and look at the FREE loading data from powder manufacturers. There’s no excuse when the data is free online.

There are 2 basic types of hulls being straight walled or tapered walls. Within these types there are a multitude of variables that vary depending on the brand of hull and components used.

Don’t EVER ASSUME a load is ok unless you find it published in a reloading manual or it’s online from a reputable source. Switching components is never acceptable. Do your homework before proceeding. Good luck!

The OP asked a basic question the answer to which lays bare a significant amout of complexiity.

There are lots of differences between hull types (depending on what you mean by "type"). Generally speaking, there are 2 "types" of hull: (1) tapered walled hulls (win AA and Rem) and (2) straight walled hulls (Fed and all Euro hulls).

Wads are designed based on these 2 basic hull types. Then, you get into issues such as base-wad height. Not all the straight walled hulls have the same base-wad height, which leads to variation in the height of the crush section of the wad needed.

So it does make a difference and you can't start with a bushel basket of mixed hull types and expect to run a single recipe through them all and expect uniform results. You will have to separate then by type and then again by manufacturer and use different recipes depending on hull type and and manufacturer. It's simple.....

Change an ingredient in a baking recipe and the end result will most likely not be favorable.

Reloading recipes are not indifferent.

That stated, there are minor cross overs that could/kinda of work with select powder/wad combinations. Crimp won't be ideal but they'll shoot.

What recipe and hulls were you in question of interchanging?

I guess that's possible, but let's look at this from another angle.
Does this OP, actually believe that the powder manufacturers, Lyman, Claybusters & Downrange, just to name a few, actually spent the hundreds of thousands of dollars to produce their data for nothing?
Sorry, I can't buy the, benefit of the doubt reasoning.

Explain. How so? You've never seen a kaboom with a factory shell? They happen, I have seen several. The worst I've seen with handloads is having to knock wads out, and the occasionally embarassing shell where the shot practically rolls out the end of the barrel.

If you're just messing with Charlie, I understand. ;)
