Yeah...you're just glad you finally got 'em through that steel plate! I remember your hints of hang-dawg when they didn't make it all the way through on a previous post... :lol: Can't wait for the action production!

Mine LOVES 45 gr under 230's. Action cycles flawlessly, brass falls in a pile. they'll blow a small block chevy water pump in half too. :shock:

I've been through about 250 at that loading, worried me at first, i'd pull the bolt after each session looking for damage, but none. They feel almost tamer than the factory loads to me. I seem to have less extractor marking/brass abuse with these loads than the factory loads as well.

My experience has been similar. The action seems to cycle very well and my brass looked great I've still got some pictures to review and a video to finish.

The MagTech 230 gr FMJ is listed as having a diameter of .451 vs .452 for the Hornady 250 gr and 225 gr FTX. I am assuming that the missing .001 is not significant?

Also re the bullet drop chart, while the BM round and the .308 look pretty much the same out to 400 yds, I am wondering what the actual drop is. Since the vertical scale is 1200 inches (100 feet, if my math is correct), I think there is still a difference of 20" or so at 400 yards, which is not visible on the chart.

Now, to go read up on the LG crimp. Unless someone would like to explain it further here?

You should be able to find the LG crimp discussions and pics using the search function on the campfire here...

Due to liability concerns, and the fact that every rifle has small variations in chambers, I can't load for others. These loads MUST be carefully worked up in the rifle that they will be used in. I'm very sorry. But your safety is most important.
Also, for what it would cost you in the components, brass and ORMD/HazMat shipping costs, you could probably get a good start on a set of dies. I wished there was a short cut but fact is, QuickLoad indicates that these loads have the potential of exceeding SAMMI pressures.

And they do, remember I say that Hornady's Lawyers won the engineering argument, for they were the ones that set the SAMMI Spec., as your loads seem to prove. BUUTTT, as you said ..""These loads MUST be carefully worked up in the rifle that they will be used in. I'm very sorry. But your safety is most important.""..

Meaning, it doesn't matter what I or others say, Standard Safety Procedures are your responsibility and yours alone!!
