I haven't tried the Mk 60mm as a clipon yet (to busy using it as a rifle scope) ... but I thought I'd try the new IR-Patrol.

Image

That's the Patrol in front of a Burris xtr2 1.5-8x cq-mil scope.

The reverse USGI 3x (pvs-14) magnifier is screwed in to the back of the PVS-14 lens on the rear of the patrol. This shrinks the clipon mode image in the patrol and might also extend the focal length of the lens on the rear of the patrol. However it works, I'm getting about the same 8x out of this sucquer I got out of the SNIPE. Those of you making hollywood movies out of the backs of your day scopes might need to stop at 5-6x, but it is WAY better than the 1x you get just using the raw 14 lens on the back of the patrol.

Thanks to Pete Lesbo of i2 tech for the tip. I don't care what they say Pete you are a GENIUS !!! :D

Finally got new NF 7-35x Tremor-3 scope. Was 6 weeks in the waiting ...



Mounting on .50BMG today. I will probably first shoot it off the .300WM, but mounting it on the .50 since he has no scope right now. Everything seems to fit.

Weekend summary

==
.50BMG familiarization
.50BMG(32)
Night Force 7-35x tremor-3
spec rest tripod

Fired 11 rounds of API reloads, my "plinking" ammo.

8 from 100yds and 3 from 500yds.

5 of the 8 from 100 were from the tripod and 3 from prone.
The 3 from 500 were from prone.

Image

The first two off the tripod both caused the gun to come out of battery.
I removed the bipod and seated the forward tripod yoke in the bipod slot.
That solved the out of battery issue.

Image

The wind was still blowing me around too much for zeroing standing up, so
I switched to prone.

Image

The rounds were still moving around too much, so I checked the scope. I torqued down
the ring screws, but I forgot to torque down the mount screws. The mount was loose.
I hand tightened and the wobbling stopped.
I got 3 rounds in the 10 ring at 100yds, but call those random hits.
I still wanted to try 500yds because I thought I was close enough to get on paper.

Image

So I moved to 500yds and fired. The hold was 2.4 up. But I was low with all three rounds.
The sight height was 2.75 inches and later I checked it and that was correct.
I think I was "muscling". If any gun does not require muscle it should be this one,
since it is 25 pounds empty.

I got some decent practice moving this crap around. The tripod is 50 pounds, the gun
is around 30 pounds. The 150rds of API felt like another 40 pounds.

Got practice removing and reinstalling bipod, had never done that before.

Got practice tearing down and setting up.

The most surprising aspect was that the felt recoil, was significantly less from the tripod
than from prone, that is, once I got the out of battery situation taken care of.

The magnetospeed worked fine. I checked it after every round and it remained tight.

But I wonder if the magnetospeed affects the bullet flight path. Like you can
sort of "pre-zero" with the ms on there, but need to take it off to
tighten up zero?

The raptar mount came loose. I don't have a tool to torque down one of the
screws, it is down in a long hole. But I increased the torque on the
other screw to 22.5 up from 15 and hand tightened the one in the hole as much
as I dared. They make long armed bits and I have a few, but not a T10 (yet).

==
Creek walk
5.56(18)
L&S mk6 3-18x tremor-3
raptar
rmr
m190 tripod
ops core bump with comms
pack

Image

This is in preparation for a group night walk in 3 weeks. Wanted to first practice
in the day with light load.

Walked a mile in the creek and along banks. Setup and the tripod twice and scanned
into surrounding fields. Also leaned against trees and scanned.
I realized I don't know how to adjust the diopter on this sucquer.
Later I looked at the manual, but it tells you how to adjust for mk4s and this
is a mk6. I don't want to turn the eyepiece too hard and break sommething, so I will
call L&S Tuesday. So that made things a bit fuzzy even with parallax removed.
But I could still see fine. Cows at 3 miles were identifiable on 18x.
Some folks think Kansas is totally flat. Not around here in the flint hills.

Image

Image




Moving up and down the banks requires care, it is quite slippery with plenty of mud.
When I got back in the house, the bipod fell off. The keymod came loose.
Something else to check.

==

Image

ODIN as a clipon in front of Burris 536. Tried the reverse 14 3x magnifier on
the back of the ODIN, which is a pvs-14 lens. It is a little fuzzy at 5x but the
main problem is parallax. I will try it, but I don't expect it to be accurate
enough to hit mice at 25 yds. You have a 2 inch target and the parallax wobble
might be able that. But I will try it.
It could be these reverse 3x thingies will work on parallax free or parallax adjustable
scopes, but not of non-adjustables.
The M69 mount is nice because it allows the optic to be raised or lowered
to line up the verticle.

Charles Hathcock behind a field modified M2

Image

==
Same weapon with more resolution in the pic.
Image

That's an 8x unertl scope for which Hathcock made the mount for the M2.

He used it to kill a 12 year "mule" moving a cache of arms forward to the enemy ... and 2,500yd shot. Well 2 shots ... the first disabled the bike, the second killed the primate. A record shot that stood for 35yrs.

They don't make 'em like Charles Hathcock any more.

The M3 tripod under that M2 has the "traversing and elevating" attachment. A wheel to allow fine adjustments and a twist lock to lock/unlock traverse. Not all M3 tripods have the T&E by default. Hathcock's did. The designer of my Spec-Rest tripod, shown above with the Barrett .50BMG also has the equivalent T&E capability.

Jeez Wilkerson.... another $8000 rifle on a $1200 tripod to punch some holes in plywood ?.... being that wealthy must be cool.... I can't imagine how many things I'd have ahead of that on a list of things for $10,000... but you have your own priorities I guess...

What I paid for that gun on GB 2 years ago, wouldn't buy one of your boats ... it took me 2 more years to accumulate the rest of the crap I needed to shoot it! That's the single shot version!

She got herself a new wrangler with her bonus ! :)

Attempted to test ability for PVS-14 3x magnifier screwed on behind ODIN monoccular, to act as "clipon" for Burris 536 scope on .22LR.

Here is the .22lr upper with the ODIN, 3x magnifier and 536 scope installed, prior to the activity.

Image

==

Here is the .22LR on the tripod at 25m. I zero the .22LR at 25m (or yds previously) because the .22lr is used as a "ratter" and critter control system around the coop ... and typical engagement distances run from 10yds to 60yds ... and the eley 36gr subsonic double zero is 25/50 m.

Image

This was one of the easiest zeros I've done. Three 3 rd groups, off the tripod, tight enough for my purposes, my goal is 2 inch accurate and precision as that will take out the rats and mice. First three round group low and right, second 3 rd group low and right but closer, ,third 3 rd group dead center.

Image

==

Then mounted the ODIN on the M69 mount with the 14 3x magnifier on the rear. Fired 10rds in pairs. Kept adjusting the odin reticle, but even wild adjustments made little impact on the POI. After 10 rds, I tried adjusting the ODIN height up a little on the M69 mount. Fired another 8 rds in pairs. By holding at 11 o'clock on the outside of the circle of this scope (a circle dot 5x scope) I was able to get within 3 inches of the center of the handwarmer.

Then fired 8 rds with aim point a tad to the 4 o'clock, that is with a gap about 1/3 the thickness of the circle in between the circle at 11 o'clock at the lower right corner of the handwarmer. That put most of the rds on the handwarmer.

Image

Unfortunately, I do not think this is a viable solution for controlling rats. Tiny amounts of change in the POA produce wide changes in the POI. So I am calling this idea a no-go with the ODIN. Will try with the Patrol, maybe it will work better. And will first try with less magnification on the day scope, the 5x might be an issue.
