Loading SS109 projectiles

[teratos]

Can't find a lot. Anyone have good recipes they'd care to share?

I got real good results loading them with 22.3gn. IMR 4064 in LC brass seated @ 2.260'' I was hitting sub MOA at 100 yds. from a 20'' bble 1:9

Sorry, I don't have a velocity for you.

24gr of h335 in lc brass.

Thanks. Going to Cabela's tomorrow to get some powder. Just getting a feel for what works.

May try searching also for XM855 load data (the same boolit)

 

[Bolts Rock]

BL-C2 will also work for that bullet weight.

Couldn't find anything a really felt comfortable saying "I want to load that!"

Gotcha.. sorry, haven't loaded any of them yet, but I'd look for H335, IMR4064 as mentioned, and would even consider Win748 if I were to test some out.

Yep, 3 good picks.

Is OP loading any other cartridges? Might be a consideration that also influences his choices.

I've got a lot of brass and projectiles, so should be a one trick pony for now.

If you can find out who makes the SS109 boolits, you can track down the manufacturer and ask them what powder and charge weight ranges you can use.

Shouldn't there be a standard load? I'm a noob, so not positive.

There is a mil-spec load, but... that's not necessarily 'standard' by reloader's means...

We pick a set of components and load a range of loads to see what it does... if some work, refine them a bit more, if not, pick a different powder and start over.. lol

The Mil-Spec M855 load....

Not really since most factory loads are done with bulk powder not canister powder like reloaders use. Similar but very different fishes there.

The beauty of reloading is that it allows one to refine a load for a given set of components, usually starting with a particular projectile and then work with powder type, charge weight, sometimes OAL to refine a load that work the best in YOUR weapon... they all differ and a 'standard load' is a bit of a compromise that covers 'most weapons' in that caliber.

Reloaders have learned that you can really optimize a load for a given boolit/weapon combination with a little patience and testing that produce the best results with 'that particular' weapon. No two are identical, the all differ a little, and reloading allows you to find what works best in a given weapon.

Another thing is that you can create highly accurate ammo, using non-match components, that can be comparable to store bought match ammo.

If you use match components, you will be able to create ammo that far surpasses factory match grade ammo.

There is also a misconception about a single stage/turret press versus a progressive press, in regards to creating high quality "match" grade ammo.

The people that believe that, have not run a good progressive, that is set up properly to keep the exacting tolerances for the "match" grade reloads. I can run my 550 for 308 and maintain 1/1000th of an inch for OAL, in regards to where I have it set. I can maintain that tolerance across all calibers that I load for.

My dad loads ammo on a single stage and I can maintain tolerances that are better than what he can do on his single stage.

If you are using a Dillon, do not use extruded powder in the powder measure. The Dillon powder measure is meant for use with ball or flake powders.

I attempted to use IMR3031 on mine for 308 and my charge weight was set to 40.0gr on the nose. I threw 10 charges and was horrified to see that the charge weights ranged from 35gr all the way up to 44rg, with absolutely zero consistency. Once I calibrated for ball powder (W760), I was dead on with the charge weight I calibrated the measure for, across all rounds that I generated.

Thanks for all the good advice. These will be the first boolits I load. I'll let the wife fire them and I'll watch from a safe distance.

That's what I do!
