What's a "standard velocity" load that will function an AR with SS109s?

[Bexar]

I have a considerable amount of SS109 projectiles I'd like to have a plinking load that will reliably function a like knew M&P15 16" 1-9 twist rifle. Don't need and even prefer it not be a barn burner just a tin can assassin.

I have IMR 4895...IMR3031...H335...and BL-C2.

CCI 450 small rifle magnum primers.

Once-fired LC-brass.

I'm saving the new brass for some Sierra SPBT hunting loads.

Thanks

Any data from load books or online PDFs with those powders will function your AR.

I would pick the one that uses the least amount of powder per shell for plinking. Most times, this is the faster burn rate powders.

Don't know about the SS109, but was using 25grns BLC2 with 62gr Privis, seemed to shoot well in my AR and Mini14.

Just a note, you should have asked about a standard pressure load, not standard velocity.

Of the powders you listed with those magnum primers H335 will match up well. With that 55gr bullet I use 25.0gr H335 as my standard AR-15 load. In reality all 4 powders you listed can be used but IMO H335 is the best choice for the .223 w/55gr bullet. Next would be BL-C(2) then IMR4895 and IMR3031 last.

Maybe I don't have the bullet descriptions right but isn't the SS109 a 62-63 grain bullet.

Thanks

My mistake, sorry, the SS109 bullets are 62gr, the M193 bullets are 55gr...

Either of ball powders (H335 or BL-C(2) ) will still work well with the 62gr bullets.

I use 24.5 grains of WC844/H335 under them.

Something to keep in mind is that lower pressure rounds are not going to burn as cleanly. That is the name of the game with an AR-15. You don't have to run max, but don't just get it to barely scrape by.

Any of the start loads for 69gr bullets should operate your Mp. Pick your powder since they all use similar amounts but you can save a little by using the one that has the lower charge wt. Your mag primers will work but are not needed.
