That was the plan ole LSS.A little prototype action, circa 2014.

So it was a take off barrel? Still seems to hold its own!Ten rounds. Not too bad for a near 40yr old Douglas tube.View attachment 7371738
Awesome, gives me some faith in using my take off. So that’s a 700 with a Douglas not a Hart?It’s a take-off barrel. Didn’t even have to cut it or the action. It screwed on and head spaced, so we let it ride.
That's right. Douglas. It's a SWAT rifle.
Thanks, Mr. Huskey. It's a retirement gift for my first sniper team leader. I learned an awful lot from him and he's one of my best friends. Walked through many doors with him either right in front of or behind me. Go anywhere with that guy... You know the type.
From little things I've been able to get him to say over the last two years I've been scrounging parts, I think this will be exactly like his first FBI sniper rifle. I even got within about 2,000 serials of his, which he still has the logbook for. I'm very excited to hand it to him.
A question, how effective are the shorter barrels? I know we talk on here a lot about how they still keep their accuracy, if just a little velocity loss. It seems to me that would be a small adjustment. And, providing all the precision is put into the rifle, it shoots just as accurate? The gain in manueverability in tight areas plus not needing a really long-range rifle make it worth doing it that way I think. What's your take on that?I've gotten several questions via PM regarding the FBI Remington 700. They pre-date me, but in talking with guys I know in Quantico, here's the scoop.
With regard to the Remington: There is a distinction between a SWAT rifle and an HRT rifle.
SWAT:
Rem 700 action
Douglas #6, 12twist, carbon steel
Leupold 3.5-10 Vari-X III with either Duplex or Mil-dot
Leupold or Redfield scope mount, bottom screw rings
HRT:
Rem 700 or 40X action (due to clip-slot for Unertl mount)
Hart #7 contour, 12twist, stainless
Unertl mount and "10X Sniper" scope
McMillan Hunter, A2 or A3 stock for either, depending on timeframe.
That's pretty interesting. I picked up a FN PBR a year or so ago, and wow, does that thing wants to fly all over. Load it with light/moderate rounds and I can control it.The short barrel guns are plenty effective for what LE snipers do. In the case of the 16" FBI gun, the few hundred of them I have seen/helped chronograph run about 2475-2500fps with Fed Gold Medal Match 168gr ammo. And, they seem to all shoot "about" 1MOA. They shoot ok, but not great. And, getting that 1MOA performance takes work. It's an unforgiving rifle to a shooter who's not applying the fundamentals. I've seen more than a few students come through and complain that something is wrong with his/her rifle... "I shoot an AI on the weekends and can stack rounds on top of each other, but this is all over the map!" Give them a new scope/rifle and the same thing happens. If you think think you can do the free-recoil, thumb-on-the-side, gamer crap, this rifle will quickly reveal your weaknesses.
Overall, while I can't deny the size/length of the rifle lends to its mission effectiveness, I don't like firing it. I don't like the chassis, the butt stock, the scope, the muzzle device, or the twist rate. I much preferred shooting the HS in its original form.
Long story short, the size is right...
I wonder if anybody here in the topic remembers when Federal dropped speed on the 168 Sierra from 2750 to 2650, and why....
A comprehensive test to determine the relationship between velocity and accuracy at various ranges was initiated by Frankford Arsenal in 1961 and completed in early 1962. These tests were conducted at ranges of 200 to 1000 yards using velocities of 2300, 2400, 2500, 2600, 2640, and 2700 fps. At the conclusion of these tests, it was determined that for ranges up to 600 yards, the best accuracy was achieved with a velocity between 2500 and 2600 fps. On 23 August 1962, an Engineering Change Request was issued that changed the velocity specification from 2640 ± 30 fps to the present specification of 2550 ± 30 fps.
In response (to poor accuracy of M118 from the 1970s era) in 1980 Lake City began developing a more accurate 7.62 NATO cartridge for match use. The primary focus was on bullet quality with examples from Lapua, Nosler and Sierra being tested. The result after two test NM lots was the M852 match cartridge, which utilized a Sierra 168 gr. match projectile and 42.0 gr. of IMR4895. This load showed a nominal velocity of 2,550 fps at 78 feet, which corresponds to an actual muzzle velocity of approximately 2,600 fps at the muzzle of the M14. The new load was very successful, as the accuracy variability between lots diminished. While the new load showed accuracy similar to the old pre-1968 M118 NM lots, the load was not suitable for long range use, that is at distances over 800 yards, as it went subsonic around 860 yards. This was primarily due to the lower BC of the Sierra 168 gr. (~.441G1) vs. the 174 gr. Lake City projectile (~.514G1); therefore, for Palma or events past 800 yards, M118 or service team developed handloads remained the only solution available.
Others will know more, but my understanding is that Federal typically loads their 168 GMM ammo to ~ 2600 or 2650 fps - as it is an accuracy node out to 600 yards - verified by the US military during the NM M14 program way back in the 1960s. I could be wrong, but the past 20 years or so, Federal 168 GMM ammo has been loaded with a medium-rate burn powder with a port pressure level that is safe for M14s/M1As. A lot of matches were won with Federal GMM in National Match M14s during the 1980s-1990s for all events out to 600 yards - before the NM M16's took over at Camp Perry.
As your question about 'why' they would load it at 2650 fps? Well, I suspect Federal is still catering to the M1A crowd, and slightly downloads their famous 168 GMM ammo so its safe and accurate in an M1A. (It's still my favorite factory ammo in my M1As, and I use it as my 'control' load when handloading for an M1A).
Here's some history if interested: Federal's 168 SMK match round is listed on the boxes at 2600 fps or 2650 fps (using 24" barrel), based on what is written on their more recent boxes. The old 'red box' ammo from 1988 doesn't list velocity, neither does the silver 1991/93 dated box. The 1998 dated 'white and blue' box lists 2600 fps. The more recent 'orange and black' boxes dated 2009 reflect 2650 for the 168 SMK (and 2600 fps for the 175 SMK).
Here's a link with a lot of info re the old M852 round that used the 168 SMK, but below is the key finding from military testing for the M14 rifle:

All you ever wanted to know about M852,
but were afraid to ask . . . NOTE: In the study cited, evaluations of several commercial match grade bullets for their potential to improve the accuracy of the 7.62mm M118 Match Cartridge. It is inevitable that comparisons will be made between the performances of the various manufacturers as...www.m14forum.com
The 1962 Change Request being referred to re the 2640 fps for the old M72 match ammo (30-06) - was applied to the then-new M118 Match ammo (7.62x51mm) at 2550 fps (both using the same 174 grain FMJBT bullet of that era). I mention this b/c the same 2550 fps was specified 20 years later (circa 1981) when the military adopted the M852 match ammo that used the same 168 SMK that Federal still uses today in their Gold Medal Match 308W ammo. I should note that the muzzle velocity of M852 out of bolt action rifle with a 24" barrel is in the 2600 to 2650 range, but out of an M14 its about 50 fps slower due to the shorter 22" barrel and gas port that bleeds off some of the pressure. (5th picture shows some 1987 era M852 Match with the 168 SMK bullet. Note the velocity of 2550 fps - but not stated is that refers being '78 feet from the muzzle,' per the US military's legacy early 20th century testing methodology).
Excerpt from an online article that has unfortunately disappeared, 7.62 NATO Long Range Match Cartridges, By Frederick Salberta:
I think this is why old-timers who competed with the M14/M1A 'back in the day' - recommend that whatever medium burn rate powder one uses for loading the 168 SMK, try to load the charge weight so its as close to 2550 to 2600 fps at the muzzle as possible - at least that is what I have heard time and time again. In a bolt action rifle, obviously there is no such thing as port pressure, so one can use a variety of burn rates and bullet weights, but that is not the case in the civilian M1A (based on the M14).
(Last 3 pics show Federal's American Eagle 168 OTM ammo that is designed/marketed specifically for the M1A, and is a slightly cheaper alternative to the 168 GMM, - but I will note that velocity is the same as GMM, 2650 fps at the muzzle with a 168 grain 'Open Tip Match' bullet).
(For 1000 yards, typically different bullets were used due to the instability of the 168 SMK beyond 800 yards. I will note that based on that article by Frederick Salberta, for the 1000 yards matches, in the 1980s/early 1990s the USMC did load a very hot 168 SMK load called the "G4" load - and it was strictly on virgin LC brass and it was a once-fired proposition with all that over-stressed brass collected for disposal after the match. The gas system on the M14 rifle was modified with a larger gas port for all the additional port pressure. The long-range M14 rifles set-up for the G4 rounds were dedicated, and no other ammo was used in them. The reported velocity was 2800 fps out of an M14, so it was still super sonic at 1000 yards, but it was hard on the guns and I assume barrel life was short too... The 175 SMK bullet came out in 1995 and fixed that range limitation inherit on the older 168 SMK design).
Apologizes for the verbosity, but I have read a lot about this topic, and I hope some of this info was helpful.
So if I’m reading this correctly, either redfield or Leupold bases/rings would be correct for my pre64 m70 build? And as far as the mcmillan stock went, I ordered mine June 26th, and received it last week. Fastest I’ve ever had a mcmillan go through, lead time was quoted at 5-6 months.

Thank you sir, was able to grab a Leupold vxiii 3.5-10 target model today on eBay also. Just need my barrel and scope mount nowBottom screw redfields, yes, per Skunk and what I saw, handled, and shot.
Great news on the stock. !!!
Because your question opens the door to the politics of the time and how people feel about it. @Skunk answered your question about the rifle. You asking why we're not happy about your questions shows you'd rather go down the politics road instead of the "what about rifles of the time road".Why were you upset with my question concerning rifles used at Ruby Ridge? The question was about what guns were in use at the time, not about killing Randy Weaver's wife and her son's dog.
