I'll throw in my findings. These are loads I found nodes for with my rifle. Higher charges opened up then came back in slowly, but primers started showing more cratering or a piercing here or there. With the mid range charge weight grouping as well as it did on the ladder, I stayed there and messed with it. Rifle is a Aero M5, 22" Wilson Combat SS profile fluted, 1/8 twist, Steiner 3-12x50 Military Tactical G2B reticle. Hornady brass (trimmed to 1.910) 108g Hornady ELD Match WLR primer (used CCI 200, 34 & BR-2 with no real changes noted) 39.6g H4350 Projectiles seated to 2.800 COAL Velocity ~2940-3000 fps, average group ~.8 MOA @ 100m Hornady brass (trimmed to 1.910)107g Sierra HPBT Matchkings WLR primer 39.5g H4350 Projectiles seated to 2.800 COAL Velocity ~2900 fps, average group ~.7 MOA @ 100m I haven't messed with seating depth yet, but may yield nothing due to mag length restriction. Atmospheric conditions when the Hornady ELD's were run was ~25-28 hotter/~23% more humid/00.14 inHg less pressure. Brass itself was in good shape. No swipes or smears until near/at max charges. Primer pockets are loose after only a couple loadings. I'll be switching brass and primer sizes soon to see what works better/best for my rifles. Groups could be better if the shooter (me) was capable of more. |
Every cloud has a silver lining (except for the mushroom shaped ones… which have a lining of Iridium and Strontium 90)

Hodgdon H4350 powder is obviously the favorite powder for heavy (100+ grain) bullets and 6mm Creedmoor.
Are there any alternative powders to H4350 that perform as well (or nearly as well?). Reason: phoned around and everyone is out of H4350 round here; don't want to mail order. |

To answer your question: I just ordered a bunch of 108 grain Hornady Match ELD polymer tip BT. As far as the powder I have on hand, I am thinking of using H380. I think H380 is suppose to work well in 243. I also have H1000 - but not sure if it will work in Creedmoor (seems too slow). Would CFE work, possibly? (I have a pound on hand to try). I have a RPR in 6mm Creedmoor. Will report back how it goes. Thanks again, |

In response to Hagdaddy’s post about StaBall powder above: - here is a thread on this promising new Ball powder that is temperature-stable: https://www.ar15.com/forums/Precision-Rifles/Win-StaBALL-6-5-powder/10-9833/ |
