At first the whole HTIR concept was all about bridging the 300 to 50 BMG gap with a opperator portable rifle ( not crew served ). As developement goes on I am starting to see potential for the same platform 16 lbs or less that would exceed the 50 BMG in every performance aspect. Hard material penetration with a 375 version could be in excess of the 50 with proper bullet developement. All of the people I know with real hard/soft target field experience complain that the 308 weighs over 17 lbs and most of the 50's weigh over 30 lbs. My initial idea (I started it in 2002) was to cram as much performance in to a package as possible that weighs no more than the 308 version currently fielded. Now I am seeing the posibility of a rifle that truly has 50 performance with 308 portability.
Sometimes Kirby scares me with the way he thinks [img]/ubbthreads/images/graemlins/wink.gif[/img], the part that really scares me is when I go, that's a great idea.
In talking with Richard he has said that jacket thicknesses could possibly range from 0.030" on the light side up to 0.065" on the heavy. Not these 65 thou thick jackets would not be worth a hoot for big game hunting but for hammering hard targets such as light armour and barricaded targets I suspect they would perform very similiarly to the 647 gr 50 BMG ball ammo but should be much more accurate.
A 425 gr ULD with a 0.065" thick jacket loaded to 3200 fps would make short work of any conventional vehicle out there.
I talked with my reamer maker contact and they want to get rolling on the 375 AM right now!!! Seems they like the idea a bit!!
Wonder if we could hit 4K with a 260 gr Accubond??? Bet we could!!
Good Shooting!!

Lets get back to the point of this post, That being Shawns great LR hammer not a post on AMs. Just wanted to bring up a couple points but do not want to totally hijack Shawns post.
Back to the 338 Edge and tiny groups at 735 yards!!!!

I'm almost speechless when it comes to the accuracy of this round. The more I read about it the more I'm impressed. I realize that a lot has to do with the shooter also, but dang, to be getting those kind of groups and that kind of power at that range......wow!
Has anyone shot any groups at a mile with the 338 EDGE?
I hope to get setup for mile shooting very soon. I have an OK location and am building a steel target 18"x18" for mile shooting. I like steel. I will post when I get it done. The futherest I have shot an EDGE for group is just a shade over 1300 yards (1306-1309 were my readings). The best 3 shot I got was 5 3/4" ( I measure with a tape when thay are that big ), the average was 7-9". While this is outstanding performance I had unusually near perfect conditions. I practice on a plate at 1140 yards it is 10" round, same as the one in the picture, in good conditions it is not a big deal to hit it every time. I would be tickeled to death if I could keep all 5 rounds on a 18" plate at a mile. I know some of the other EDGE owners have expressed interest in 1M shooting hopefully they will chime in if they got around to it.
Thanks for the info. Sounds like you're still getting 1/2 MOA or better at 1300 yards with the EDGE. Which is great! I would think that at one mile, you'll still be able to achieve 5 hits on that 18" plate. (I like steel too, something about that "ding" sound just brings a smile to my face [img]/ubbthreads/images/graemlins/grin.gif[/img]) If I remember right, running the ballistics calculations on a 300gr. SMK, it is still going supersonic past the mile point, which will help considerably with getting those hits. This is one reason I decided to have you build a 338 EDGE for me, instead of rebuilding another 300WM.
We're trying to get a "One mile club" going at Parma Rod and Gun club. So we're trying to set some parameters or rules that allow a person into the "club" so to speak. 5 hits out of maybe 10 on an 18" plate might be a good starting point. We were thinking of starting with a 30" plate and working from there.
Let me know how it goes when you get up and running. I'd like to see your results.
