Does anyone have any experience loading for the Remington 700 5-R 24" barrel... I'm having all kinds of hell getting it to shoot 168s and 175s... It loves 130s and 150s but that doesn't get me much after 600m... Thanks in advance

I could not hot rod my 168's in my .308 so i had to find the low accuracy node.
42.5gr varget, start at 42 and work to 43 if you have varget.
I did have some that liked 45 but beyond that groups went to crap. Some have found 41gr as a start to find the low accuracy node.
What have you tried?

the 150 and 155's liked to go fast though in the mid to upper 2900fps area. Even in my 30-06 the 155 wanted to go 3176fps.

My 24" Armalite AR-10T works very well with 44 grains of Varget and Magnum CCI primers in Federal brass behind 168 A-Max bullets. It has worked out to 800 yards for me so far. My Velocity out of the AR-10 is 2750 at 10 yards

thank you to everyone who helped out with this... I have come to the realization that the 1-11.25" twist sucks donkey balls for heavier bullets... although with 47.0 grains of imr 4064 and a 130 gr speer HP I can shoot sub .5, really it was .469 groups with 3 shots and 0.848 with 5 shots... and I'm not a very good shooter... its either luck twice over or it actually works... running varget the best group i had was a 168 berger classic hunter running 41.5gr i shot a 1.155 3 shot and a 1.345 5 shot... i have since bought some 150s and well see what they can do... and for the worst group 190gr sierra match i shot a 2.57 2 rounds and 3 more that didn't even hit the paper... so I would say the short of it is if you want to shoot heavier bullets buy a faster twist... DUHH... My fault...

What brass you using?
How many rounds have you shot since you cleaned the copper out of the barrel?
My .308 gets sloppy after 25 rounds or so.
The old 30-30 is slower twist than that and shoots long heavies fine but they are slower.

Sometimes a gun likes what it likes though
Are the good shooting bullets flat base or flatter base that the heavies.
My 30-06 did not like boat tail bullets, I recrowned the barrel and now the boat tails group much tighter.
It cut those groups in 1/2

I'd try making 5 rounds on each side of the of your known charge. For example if you are getting bad results using 42 grains of Varget on a 168 bullet. I'd make 5 rounds with 41.5, 5 with 41.0, 5 with 42.5, 5 with 43.0 and see which direction your groups improve. The load range for Varget in my Lyman book for 168's is 41.0 to 45.7+. You might even try a different powder like IMR 4895. Something with a different burn rate can help as well. Every gun is different what may be perfect for one guy may shoot like crap through your gun.
