I have a Remington SS 5R 24 in Mil Spec bolt gun. I will be using Reloader-15 and IMR 8208 XBR From personal experience what has been the best long range bullet you have used.
Amax 168 and 178 175 SMK 168 SMK 175 Nosler 155 SMK I will humbly except any and all imput/help on this subject. I'm looking at shooting 600 -1000 yds I have worked up a load using 175 grain SMK and 175 grain Nosler on top of 43.1 grains of Reloader-15 used fire formed to my chamber Lapua brass with .002 of neck tension on bullets. Shot .25 average. from bench rest. I have not had a chance to shoot further yet. I am interested in what you have accomplished with these bullets and powder used. You don't have to give me your load data because I can work up that. |

For long range out of my Remington 700 308 I keep going back to 168 Hornady AMAX or 168 SMK.
You have to pick one because they aren't exactly the same bullets and I just can't decide. 
Today it's the 168 AMAX. 
Whatever you have to drive it to 2600 FPS will work just fine, I think. Right now I'm working on a VV N150 (new powder) load with it and I have gotten absolutely nowhere because I'm also moving to a Burris 6-18 scope from a leupold 3x9. New loads and a new scope. 308 is one of those calibers I have trouble reaching nirvana with because I keep changing things. I'm thinking with the more powerful scope I might end up with a heaver bullet. |

My favorite, in 308, is the 190 Sierra MatchKing. It goes out of the 24" barrel at 2650 fps. It does very well in the wind. It's better than the 168 for longer range. I'd say the 175 SMK is the only other that's close.
The only concern I have is the use of RL-15 with this bullet, I haven't used RL-15 with it. |

Sierra 155gr Palma would be your best bet. Higher BC than the 168's. The 168 is great but, nothing further than 300-600 yards.
Your gun has a 1:11.25 twist rate so, the 175's and 190's would also be great choices. 155gr Palma....fantastic though...you will not be disappointed. |

208gr A-Max 50.0gr RL-17 WIN brass CCI BR primers i need to get a chrony, but it should be about 2600fps. shoots 5 shots just under 3/4 MOA @ 300yds out of my savage 10. At 2.80 this is way, way, way, way past max. You"re right you do need a chronograph. 46.8 grains RL-17 seated @ 2.865 out of a 20" barrel pushes 2,510fps on my chrono and that's 10 feet from muzzle !! |

Forget the 168's at 1000, They are excellent bullets for 600 yards, after 800 they get dicey. Try 175, 180 and 190 SMK's, Hornady's 178 or Nosler's 175. Shoot the bullet that groups best in your rifle. 190's at 2500 to 2550 fps work great. 180's @ 2550 fps or 175's 2550 to 2600 fps work too. Much faster than this and you are over pressure.
155's work best at high velovity, 2900 fps +/- and using longer barrels to get there, not more powder. Palma rifles are built around 29" to 32" barrels to get as much speed as possible without excessive pressure. |

Thanks guys for the info. I plan on loading up several loads with the bullets and RL-15 and IMR 8208 XBR If you're buying the 155 SMKs, get the newer, redesigned Palma Match, ending in '6', I think it is. Better B.C. If you can get the Lapua 155 Scenar (or the newer 155 SMK) up to 2900+ fps (not too hard to do,) you will have an excellent 1000 yd cartridge. You can get there with the 175s, but the 155s will do it better and flatter, to the tune of </= 30 MOA to 1k. I've shot the 180/190 SMKs and at shorter ranges, they're fine. I think the 190 is preferable, as the 180 SMK is the bastard stepchild of the SMK 30 cal family. I like the 185 Lapua Scenar and/or D46 rebated boat tail, for this weight class. Unless you start switching powders, you're starting to run out of gas with the 190s and that diminished velocity won't make up for the lighter, slicker and speedier bullets, even in wind deflection. I've got 3 1/2 boxes of 208gr AMAX and 2# of RL-17, so I'm going to fiddle with this combo at sea level. Just remember, with heavier bullets, you get more recoil. Chris |

Chris is referreing to the "2156" Palma 155 SMK bullet. It's a great bullet, and flies much better.
Personal favorites would be: 2156 155 SMK 178 AMAX 175 SMK 155 Lapua Scenar 170 Lapue Lockbase 208 AMAX I usually load the 178 AMAX for everything though. I haven't found a rifle that doesn't like that load I posted. |

| I think the differences in some of the loads recommended will be lost in the noise unless you ditch the "Mark-X Pro adjustable trigger". Not remy's fault, they have been tortured by ambulance chasers into being trigger shy. I would recommend replacing it with target class timney, jewell, gisselle, etc. |

That's almost exactly what I'm shooting, except I get best results with 49.7gr of RL-17, and its out of a remington 700 ETA: OAL is 3.00in on the dot. |
| You are right about the X Pro trigger. It's not a bad trigger by any means. I would like to be able to adjust it a little more than it allows. I have 10 lbs of RL-15 and 6 lbs of IMR 8208 XBR So I am going to stick with those powders until they are gone or I find a load I really like. |

Man I'm going to order some of the 155 grain pills. I have heard nothing but good things about them Don't know as I have not tried them, but if you believe what German Salazar says in his article "Palma Basics in the USA", he is not crazy about the lighter bullets.

Buy the 190's...try them out of course....but the 155 palma's will make you very happy. |

never hurts to try something. Either way being at the range shooting is always a good thing  As you well know, opinions vary. I think if you have a chrono and get accurate velocity readings through your rifle, you'll be able to use JBM's online program to see which is going to fly truer. I don't get to shoot at 1000 yds much, so 100 yds and 300 yds is more common. However, I do shoot bullets from 150gr SMKs up to (soon) the 208 AMAX and all inbetween, so I have a little experience. The 155s, if they'll shoot, are pretty slick. I've got a basic program on a Palm PDA with 100+ bullets plugged in and I'll sit out on the patio smoking a cigar and drinking a beer and I'll just plug in velocites with X, Y and/or Z bullet and compare dopes. It's enlightening. Chris |

That article seems to weigh the pros and cons for someone who shoots the Palma match both domestic (where the heavier bullets are allowed) and international (where you are restricted to the 155?), and the problem of potentially having barrel/load switches when doing that. Most of us are (unfortunately) not shooting Palma, so that is really not a consideration? |
