Hi Ed,
How much are you selling your 375HE brass for? I managed to sell my Weatherby so that will get things going on a build. Planning on the Bat-L action and Bartlein barrel with Lester Bruno doing the build.

For those of you that might have missed it, Applied Ballistics (AB) recently announced a new DVD, ELR Shooting with Applied Ballistics: Applied Ballistics' campaign for the 2017 King of 2 Miles competition." [Available at https://store.appliedballisticsllc.c...oductCode=0009 Pre-order pricing still shown.]

I pre-ordered one and received it last week. In watching it today I noted:

1. None of the AB shooters in the video were using anything "special" in the scope and mount department, specifically no TACOMHQ gear. The three team members in the Top 10 were using NT ATACR 7-35x56 scopes. A shot earlier in the DVD showed an Ivey mount on one of the rifles but I was unable to identify it in the actual competition section of the video.
2. At one point the front end of Derek Rogers scope was visible and I noted that he was using a "modifier disk" - I tried my March modifier disk on my 56mm ATACR and it would not fit. For those unfamiliar with such a device, see http://marchoptics.com/accessories . I found no such product on the NF website (at least in the Accessories section).
3. Anyone seriously considering shooting Ko2M - this DVD is well worth the tab.

Modifier disk is extremely convenient. I’ve been using electrical tape for many years. As much as I hate them you could use a butler creak flip cap and a small hole saw. Buy a few put different diameters in there.

Here is recap simple setup to get faster loads with 12ga sabots

& slugs, Example using break actions...., reaming chamber

in a 12ga break action to 3.5" with a 3.5" 12ga reamer, that isn't

something needing special order, and use 3.5" plastic cases , or

get 3.5" brass cases made. With mag shotgun primers and

our slower powder loads you can get a quarter more speed,

which gives 50% more energy...


585 Hubel Express video, 190ft/lbs recoil, heavy load, gun little light.....

Can a Bat L be used for 416 HSM or does it need a 50 cal action?

Ed: I thought the 416 HSM is to have a rebated rim - down to CT size. That would allow use of the BAT L action (which is available with CT bolt face).

The L is available 2.0" OD, same as the .50 BMG-focused EX, but the L's loading port is only 3.8" long vs the EX at 5.5". If a shooter wanted to load shell-holder-action style (remove the bolt to R&R cartridges), the L that would work just fine.

Any other issue?

You can use the factory scope caps and just have someone with a lathe make an opening for you. Jim Ketchum has made me several for the 56mm Nightforce scopes I use.
If I dig them up I will send you one.

For those that missed what Lynn is talking about, my earlier post in this thread mentioned Derek Rogers using a "modifier disk" at the Ko2K. I noted, that while I had a modifier disk for my March scope I could not find one listed on the NF site for their scopes. With that preamble...

Lynn - then I'd have to deal with junk blowing around getting inside (why I close my factory pop-up NF caps when not shooting). I'm looking for a screw-in solution like the March solution that the pop-up lens caps will fit. Did Ketchum machine the older metal NF lens caps or are you talking about their rubber lens caps? If metal, yes, please be so kind as to find and send me one. I'll live with the junk blowing around.

I found a company that supposedly makes what I want BUT their product listing seems to be a one-size-fits-all because they provide only one offering with no way to indicate which scope you have and list several NF scopes as "made to fit" but that have different part numbers for corresponding sunshades for those scopes on the NF site. I've e-mailed their e-mail address because their contact form does not "submit".

All the above noted, in reading about the mirage-reduction capabilities of "modifier disks", I found that different mirage conditions require different size holes/openings in the modifier disks. Some smart person, opportunity knocks - design and market an adjustable-aperture modifier disk. And post on CalGuns to tell us about it. Thanks.

I will post two pictures showing the modifier discs I use. They are the factory caps that come from Nightforce with the center lathe turned to a given size.
These are threaded with a shoulder and don't vibrate lose so far.
I would think someone with a 3D printer could make them out of plastic and if the shoulder diameter was the right size they would self thread themselves?

A little crazy glue on the end of a sunshade, and you're all set. $43.50 on ebay.
