I'm currently running the fed gold 168 grain and past 800 yards it is very inconsistent. Anyone here have good results with the FG 175 grain in the 5R at 800-1000?
Range Report Remington 5R, fed gold 168 vs 175
- Thread starter TAKDRIVEN
- Start date
I shot my 308 5R 20" this week at 800m and had the same Problems.
I used Remington Premier Match 168 and Hornady 168 both useless and subsonic at 800m.
A friend gave me some Surplus WM 150grs all at the target and over 400m/s at 800m (our target spotting System messures the bullet Speed).
I want to shoot 1000m with this gun maybe i Need a longer barrell to Keep the bullet at Speed of Sound at 1000m.
The guys who shot with me all had longer barell´s and no Problems.

Mine gets a steady diet of 175 Sierra Match Kings and it is always sub-MOA if I do my part. I notice the groups open up only after the bullet drops back to sub-sonic speeds (1,020 -1,050 yds.)

Should work great, people use to say (I'm assuming you have a Remington 5r with 11.25 twist) that the 11.25 twist was chosen because it was the ideal twist rate for the 175 SMK. Is it true? I don't know, it works though the ARMY has had great success with it and the 175 SMK.
What Barrel lenght do you have on your 5r? I would say if 168 ar Subsonic at 800m 175 are Subsonic too... if u shoot Factory ammo...
147grs = no Problem at 800m 5r 20"
We had some Palma shooters at the range they give me the advice to use lighter bullets...
They shoot 155grs at 1000m with Rem 700 but with a 29" custom barrel.
Give the lighter bullets a try to stay at Sonic Speed.

i don't want to step on toes here, but i do not think a lighter bullet is the answer. a different bullet may be- maybe a VLD?
for the OP, maybe it is time to start reloading? gives lots and lots of options.

It is well documented that the SMK 168 becomes unstable at that distance ( > 600 yards ). The SMK 168 was designed for accurate midrange competition and that is where it excels. The misinformation out there on the Internet is that the 168 is plain unstable. That is not true. People are just using it beyond its capability.
CheyTac82,
The information you were given by the Palma shooters is correct, but not totally complete. Yes, we use specialized 155 grain bullets for this game, but it's not because they're the "best" for this application. We use them because International Palma rules REQUIRE bullets no more than 155 grains in weight. We also use long (29"-30") barrels as you mentioned, because that's what it takes to get these bullets up to the 2950 fps range these bullets need to remain supersonic at 1000 yards. Given the choice, most of us would prefer heavier bullets of a higher BC, driven at a lower velocity. Better wind resistance, no problems in staying supersonic, etc..
As Culpeper said, the 168s were originally designed for 300M shooting, and that's what it excels at. You can use them at 600 with no problem, but they become a bit squirrelly when you hit the transonic region somewhere around 800-900 yards. All bets are off then, and you'll be much better served with a heavier bullet. With the 11.25" twist being discussed, he should be able to get away with bullets in the 185-190 grain range, no problem, and possibly up to 200 grains or so, depending on the make (length) of the bullet in question.

TAKDRIVEN,
Much of the performance you will see with FGMM 175s, or any other "factory" load using 175 gr SMKs, will depend on the velocity you're pushing them, and the elevation at which you're shooting. I've shot FGMM 175s several times at 1000 yd in F-T/R competitions out of a GAP Crusader with a 30" Bartlein 5R barrel. The elevation at this particular range (Camp Pendleton 117) is ~ 420 ft. The avg. MV for these out of this rifle is 2750 fps, which translates to just under Mach 1.1 at 1000 yd. Even though the 175 SMK transitions to subsonic reasonably well, when the wind comes up (as it usually does at Camp Pendleton), the performance isn't so great. In addition, you will typically see velocity extreme spreads from factory match ammo in the 40-60 fps range, which also is not ideal for precision shooting at 800-1000 yd.
I've had much better performance using the Applied Ballistics 175 gr Tactical load, also at ~2750 fps. Although it's pretty pricey, with the higher BC projectile and much lower ES values, it performs far better than any factory load I've ever tried. With the 24" barrel on your rifle, you would do far better to reload your own using something like the Berger 175 gr Tactical bullet or 185 gr Juggernauts. In addition to the much higher BCs possible when selecting specific bullets to reload, chances are pretty good you can safely get the muzzle velocity up a bit higher compared to factory loads, which tend to be pretty tame.

Just yesterday I had a brand new shooter make contact on an MOA sized diamond with his third shot using the FGM 168s through my Rem. mil spec 5r. We, however, were at over 6000' elevation.
