Finding the perfect Load

Well, as a newbie, I was wondering what the most efficient approach is for sorting through all of the different combinations that a guy could try while searching for that optimal load that my rifle likes most. The way I see it, there are at least 5 variables.

Bullet Brand
Bullet Weight
Powder Brand
Powder Weight
Brass brand

If you add up all of othe possible combinations that I could come up with, that's a LOT of shooting. I'm shoot
Do you stick with one specific bullet and weight, and cycle through different brands of powder and different powder amounts . . .

or do you stick with one powder brand and cycle through different bullets at one measure of powder. . . .

or do you just pick what you think is a good bullet and try different powder brands and measurements . . .

If I went through all of the different loading permutations that are available . . . I'd need 3 different barrels just to get through them all with 5 shot groups.

Any help would be appreciated.

I'm leaning towards Retumbo and Berger 180's or Swift Scirocco II 150's. I'd prefer the heaviest bullet that I can get accuracy with, as I'm hunting Elk and Mulies.

Re: Finding the perfect Load

I would like to know what the preferred method is too. I am new to the forum, but for years all I knew to do was pick a brass and primer, 2 preferred bullet choices, 2-3 powders, then load 5 rounds in .3gr incriments and record results. This last barrel experience kicked my ass. 120 rds and best group is 4" at 100yrds. Normally I can figure it out in 50-75rnds. As groups tighten or fall apart I know what direction to go. After finding this forum I realize MANY more variables exsist. COL, COAL, flash hole size, the list is longer than I thought. Any expert advise would be appreciated.

Re: Finding the perfect Load

research and start with quality tools and components.

Pick one your interested in, reaserch it, then decide if it fits the bill for you. When you find one you like you'll also be noticing a trend as far as loads go, then cross reference with your manuals. No need to go try this and try that unless you really want to. But one thing you really really need to keep in mind, is to take interwebz loads with a grain of salt untill you verify them with your manual that their not way over loaded, some guys will make you wonder how they don't blow their guns up.

And for making it all go in the same hole you can play with the primer selection.


And do it all one more time.


Good luck.

Re: Finding the perfect Load

Not trying to be rude but your response is to see what other people claim they use for loads, refrence a manual, and vioalla, sub-moa load? These modern manuals give me low confidence. They don't hardly publish cups or psi, they allow scary pressures for some (like 7wsm) while cut back loads on proven rounds like the 300 h&h. with all the variations in freebore, and components I am looking for some kind of checklist or process to narrow this down.
I bought a 7wsm this year and want to dial it in. With its reportedly high pressures I don't want to screw it up. I also don't want to load 200rds to get there.
Sorry to hijack this thread. I just want some thing technical to study and aid the process.

Re: Finding the perfect Load

I'm asuming your talking 7mag?

Bullet Brand
Inside of 600 yards=160Partitions(my walkabout 7mag), past 600 180 Bergers(dedicated heavy long range).Not saying others will not work but these two have proven to be easy to find,very effective and easy to get to shoot.
Bullet Weight
Most factory or standard barrels will shoot the 160-180.Have burned up a lot of lighter bullets without much seccess
Powder Brand
This one is kinda barrel preference but Both 7 mags do well with Retumbo.Can get more speed with a couple others but Retumbo holds good accuracy at the top end.
Powder Weight
Start low and work up....You cant miss them fast enough but reasonable to high speed works.
Brass brand
Lapua if you can find it,Hornady works good or Winchester.

Ya you can burn up a lot of supplies finding the perfect load or you can pick a bullet suited for the perpose, a couple of powders that are known performers and adjust seating depth. A couple different primers will help fine tune the end result.
