Maximum OAL will be about the same as the AR mags, 2.260

I'm a R700 guy, have several, but early issues reported on the 300 BLK chambering kept me away. I own RARR rifles in BLK and 5.56, both with the rotary mag. After handling the AR mag version, the position I carried the rifle and the mag protruding in the way kept me from going there. I'm happy with ...

I also have had the best results with the 208 Amax in a 16" bolt rifle and a 10.5" AR pistol. We stocked up before the change to ELD, wish I had bought more. My best day/group on steel was 3/4 MOA out to 200 with the rifle, with perfect light/no wind conditions. Honestly, I dunno if my set...

Dellet answered your query with a question, one requiring stepping back to the start. Choose an OAL that is similar to printed data, use the start load or something in between. I will note that, using that bullet, you can't get enough of that powder in the case to be harmful...unless seated deeper b...

Both of those young men are a fine example of what a hero looks like. I'm saddened they lost their lives. By selfless action, many others were likely spared. Prayer for the students and parents, this could happen to some of our own. Rest in peace boys.

My experience with forming in the HORNADY sizing has been positive. Once fired LC lubed, inside of neck as well, nicely formed case with zero drama. Out of about 50 cases, I had one needing a second pass, with no split necks. This was something that I just had to try. I now chop first, the longer ne...

In my part of the world, the big 30's are popular due to the longer ranges encountered. I grew up in the timber and mountains of NW Montana, the .243 was a very common youth rifle. More important than a specific caliber, can the young person shoot the chosen rifle from various positions, and be reas...

Amen brother! The whole bunny and treat thing kinda detracts from the message of Resurrection Day. Dinner here around 5, two of our kids and their total of six grands. The other two boys live out of state, one in NYC and the other in Portland. My bride in the kitchen now, I'm staying out of her way,...

I'm certain this question is one the most common, and with that in mind, you will no doubt receive any number of solid suggestions based on some who have their personal favorites. I use Dillon dies on my 550's when possible, but in the case of 300 BLK, I'm using the Hornady dies. I can use different...

The 300 Whisper and 300 BLK have always been pretty much subsonic in design and application. Yep, we can do supers in both...bonus. The HAMR, like the Whisper/BLK, appears to be a mod of another round, in this case, the 7.62X40 WT. The design criteria is for a supersonic .30 cal. round in the AR-15 ...
