Re: 338 EDGE vs. 735 YD. PLATE

JD,

Sorry I forgot, you can build the 338 EDGE on a Winchester puch feed with a wyatt's box mag. I run as short as 3.685" for the HS box mags, but really like to be around the 3.775" for the Wyatt's. I have built a couple in single shot mode that run over 4.000" while they run well it is difficult to eject a live round even with additional cuts.

Shawn,

SWEET!!! Nuff said on the rifle and shooting!!

TO everyone else, if you read Shawns posts you will have noticed that he said he was going to be building some 338 Allen Mags for customers. This is not a typo.

Shawn contacted me quite a while ago and asked if I would be willing to allow him to build 338 AM rifles for customers.

Because of my dealings with Shawn in the past and knowning the quality of smith he is and more importantly the kind of man he is I quickly agreed to release a 338 AM reamer to Shawn and Defensive Edge so now there will be two sources of 338 Allen Mag rifles. Both reamers, My original and Shawns which will be coming soon are identical in dimension so the same dies will work with both.

This will be however, the only Allen Mag available outside my shop and Shawn WILL be the only other smith that has approval by me to chamber and build the 338 AM.

Did not mean to hijack your post Shawn, just wanted to clarify our agreement to the boys before alot of questions started popping up.

Now I just have to make sure I can build my rifles as precisely as you do!!!! [img]/ubbthreads/images/graemlins/grin.gif[/img]

Good Shooting my friend and great rifle and round!!

Re: 338 EDGE vs. 735 YD. PLATE

Kirby,

Thanks. It nice to be included in a project with as much potential as the 338 AM has. I believe that the 338 AM portable version (sub 16 lbs) has potential for many applications. I believe that it would be "the" round for my initial vision of a portable "HTIR" Hard Target Interdiction Rifle that I started the 338 EDGE on. I have been looking at the BAT action specs to determine if a CF box mag feed is realistic. About accuracy of the pictured rifle. I tested 2 things on this one, 1 a break design that would tame the 338 AM on a lighter rifle (worked well). I will do a thread about the break testing later. Second was to figure the weight past the crown needed for the best accuracy and incorperate it in the brake (worked very well). The 338 EDGE is the most inherently accurate large round I have worked with. I would love to tell you I knew that when I started with it, but in reality I was just lucky. I am sure that the 338 AM is a 1/2 MOA setup, but hoping for 1/4 (you know, more whiskey, faster horses etc).

Re: 338 EDGE vs. 735 YD. PLATE

Shawn,

Yes I hear you on your ideas for the 338 AM.

I am thinking a 375 version will be even better for a HTIR but that will depend on bullet availability, I have been pestering Richard for some 410 to 425 gr ULD RBBTs for this round. I think it would make the 408 CT look silly with nearly the same weight bullets.

From my figuring top velocity would be similiar with the larger caliber bullet compared to the 338 AM, sectional density would be identical for all realistic purposed (.438(338) vs .432(375)) and BC predictions are basically identical at 0.950 for the 338 and 0.94 for the 375. Only difference is we would be looking at nearly 9700 ft/lbs of energy for the 375 and right at 8000 ft/lbs for the 338.

Momentum would favor heavier pill as well.

Only issue will be increased recoil in a portable rifle design. We will have to see how that goes.

Here is a pic of the 375 AM compared to the 338 AM, kind of silly looking with the 260 gr Ballistic Tip but I bet she would be FAST!!!! This would be my pronghorn load [img]/ubbthreads/images/graemlins/grin.gif[/img]!!!
