I have found my load on the Sierra 125gr OTM with Hodgdon Lilgun. Sierra 125gr OTM Noveske 300BLK Pistol length gas system 10", 1:7 MagPul PMAG, 30RD 125 gr Sierra OTM Hodgdon Lil'Gun 17.2gr LC 5.56, reformed to 300BLK Case length 1.358" 2.210" OAL CCI 400 Small Rifle 1/2 turn light c...

I have both the L.E. Wilson and the Sheridan Case gauge. My rifle is a Noveske 10" 300 Blackout. I am curious as to why all of my reloaded ammo will not drop into the Sheridan Gauge, but it will drop completely into the L.E. Wilson Gauge. The rounds function perfectly in my rifle; no cycling or...

With as many loads people have worked up, it is disappointing to find so few loads listed in the Load Catalog Index. I have been reloading supersonic only so far as I have been waiting t...

H2, my brother has an H I can try. I may give that a shot this weekend too. This rifle assembly has been a nightmare. Between damaged parts, lost orders and parts availability, I am ready to be done with it! Just need to work out the last couple of kinks. For a pistol legnth gas system, you want to...

I am using a mix of parts. I am using a Spike's 10" Lothar Walther barrel. The ejection issues I have been having is that the bolt will lock back on an empty mag but will not eject the spent case. If I load more than one round in the mag it just crams the next round into the spent case. I have...

I am glad to see this thread! COAL for the 125gr OTM is something I have been struggling with. Last week I loaded up a number of rounds with a COAL of 2.21" like many others have. While the bullets shot well (I ran into ejecting issues, but I think I have an extractor problem as the bolt holds...

So from my tests and there is more than I posted but they follow the same pattern so I did not include them.

It looks like he said the other tests DID follow the same pattern.

I'm getting similar results using 17.2gr of H110, 2.22OAL. I started at 17.8 and worked down by .2. @ 17.0 the groups started opening back up. http://i757.photobucket.com/albums/xx218/euricf/image-5.jpg The highest load I have done is 17.2gr. I did not see any signs of pressure so I guess I could g...

Today I went to the range to test another work up of this round and I think this is the sweet spot and the load I will use for this bullet. Noveske 300BLK Pistol length gas system 10", 1:7 MagPul PMAG, 30RD 125 gr Sierra OTM Hodgdon Lil'Gun 17.2gr LC 5.56, reformed to 300BLK CCI 400 Small Rifle...
