When I got started 2 years ago, the only place around me that I knew of was Cabela’s. I had press, dies, and 1000s of fired 9mm that I’d saved for 2 1/2 decades...knowing one day I wanted to reload. I also had Hornady 9th edition (came with the press). My wife and I went to Cabela’s where I looked at the shelves of powder and picked the only one I saw with 9mm recipes on the bottle...HP-38. I also grabbed a brick of CCI Small Pistol primers (without seeing the tiny red letters M A G N U and M). Who knew it would be a fine powder for every pistol caliber I ended up reloading, save the .357Mag...which I am loading with .38 Spl recipes? I also grabbed a box of Berry’s 115gr CPRN and got busy.
Nearly all of my early powders were serendipitous purchases, as I took huge advantage of the bullets.com going out of business sale in early to mid 2018. I ended up with Vihtavuori 3N37 (4 lbs) and N320 (1 lb), as well as 3 bottles of Silhouette and 1 of WST. I tried to get more VV N320, but all of the VV powders went quick.
Since then my powder purchases have been more thought filled, as I had specific purposes in mind...and I‘ve assembled multiple ARs. My H110 was with thoughts of loading the 357 magnum, as magnum loads. It remains unopened at this point. CFE Pistol was a strategic purchase to test against 3N37, but with (hopefully) cleaner results. I recently picked up a jug of N330, as everyone was out of N320, and it appears that N330 will fill in for nearly all of my favorite loads, and the Vihtavuori app has as many loads for it as it does N320.
My “rifle” powders are all focused on .300 Blackout...thus the IMR 4227, Accurate 1680, Vihtavuori N120 and N130, CFE-Black, and the H4198.
This takes me to my largest stash of powder...and my least favorite...I picked up 16 lbs of Universal on a Gander Outdoors clearance. When you pay less than $10/lb for powder....maybe something’s not right. Fighting terribly with this powder...but with 16 lbs I’ve got to keep working at it. The loads just aren’t right...and thus...EVERY load I‘ve tried with Universal is limper than a limp noodle. I’m at maximum on some 9mm loads, and nearly every tested firearm fails to cycle. The only pistol that tends to eat all the loads is my Kimber Micro 9. Taurus G2C fails, Beretta 92FS fails, Kahr CM9 fails, Smith & Wesson Shield fails, the Ruger runs some round, and the Glock is worst of all.
Long post...but it makes up for the fact that no one else is responding.
