I want to eliminate some of the powders that I have on hand. I know each gun, bullet weight and barrel makes a difference but there has to be someone in common either between calibers and weights. For those that know how to put together a matrix how about a little help.

Caliber 223 55 gn bullet powder preferred
68 gn bullet powder preferred


Caliber 300 BO 130 gn bullet powder preferred
150 gn bullet powder preferred
168 gn bullet powder preferred
220 gn bullet powder preferred

Caliber 308 150 gn bullet powder preferred
162 gn bullet powder preferred
168 gn bullet powder preferred

Caliber 6.5 CM 130 bullet powder preferred
140 bullet prowder preferred

Caliber 45/70 350 rn bullet powder preferred
405 gn swc bullet powder preferred

Not looking for loads data but tired of buy 5 different powders for one gun and 4 for another the to find out there is a common group of 3 that will work for both guns

Yes this will take some time and each bullet is a variable but what I am looking at is the grains of each bullet to compare.

I got way too much powder that really I should not have ,bought but when I go into reloading again 5 years ago I bought what every I could get my hands on. Instead of buying 1# cans it would be nice to buy 5 or 8 pound cans of the better powder at a cheaper rate.

I hope you are following what I am trying to do with a LOT of help.
 
Each gun is an individual as is each caliber. Case in point, I have 3 Rem 700's all in 308, all with the same stock and all with 20" bbls. For all practical purposes, identical. Rifle 1 loves 150 grain Sierra's and 3031 powder and will produce cloverleaf groups at 100 yds. Rifle 2 hates the above load and shows preference for 4064 and 168 SMK's. Rifle 3 I haven't worked with enough to determine it's quirks but I can tell you that it will be something different.
There are "stand by" powders that seem to give decent results in a given rifle but don't really shine in any of them. A load has to be tailored to a specific gun and may or may not excel in any other gun of the same caliber...
 
Open excel
1 row per caliber/bullet
1 column per powder on hand
Put a "1" in the cells where you have a match
Sum your rows/columns
Make decisions
 
For 223, whenever I load 55gn bullets it is usually for plinking. I like H4198 since they are lower recoil rounds and more economical to load (less powder). But a lot of people like standbys, like H335, TAC, etc.

Also in 223, when I load heavier bullets (typically 75gn) I am usually loading for precision, and I like Varget and 8208XBR. I've had others recommend H4895 and 3031.

Can't help you with the other calibers.

I know there is a lot of truth to this, but I've also heard that Federal Gold Medal Match shoots awesome in everything. How do they manage that? BFM?

B = Black
M = Magic

Federal is top quality ammo loaded to very exacting standards and will in fact shoot very good in many guns but a hand load custom tailored to a specific gun will shoot better in that particular gun.....
