Who says 168gr MKs don't fly well past 600 700m?

I have had good success at 850m banging 12"W 20"H steel. The other day I was shooting at 950m in 30k plus gusts and shifting winds with bands of rain then sun messing with atmospheric density very challenging. When
making adjustments for changing conditions I was adjusting on the 2" pipe of the target frame with the sand berm as a backdrop to easily spot misses. While doing this I made 3 hits on the 2" target frame. I really want
to try shooting a group at 1000 yards. I am sure it won't be stellar but would be interesting to see if the remain
stable.

The rifle was the PGW C-18 with 24" barrel! Love this rifle! I had swissin spotting for me that was a big help I would have been lost in conditions like that with out someone with allot more experience.
 
With that very same ammo I had one of the sniper candidates( a complete noob) with a shot out C3, hitting a 12x12in target at 850m in gusting winds on the 2nd shot. That ammo is Gtg.
 
They WILL tumble as soon as they go transonic... good atmospheric conditions along with a fast barrel may keep them supersonic past 800 but only just.
 
The BC on 168s is just under that of a 155 SMK. It takes a long barrel or a hot load to keep the 155s hypersonic to 1000 yards. Normal barrel and throat lengths don't lend themselves well to anything past about 900 yards for the 155, so I suppose at 850 yards you must be right near the limit for the 168s.

You might be able to get the 168s to shoot well out to 1000 yards if you have a real long throat and light cases like Winchester. Somewhere near 44.5 grains of VV-N150 and a seating depth of about 2.95" would probably do it, but why bother when there are more suitable bullets - meaning bullets with a better BC that weigh less - like the 155 SMK or Berger. These bullets will go faster and maintain speed longer than the 168.

If you want a nice load for long range try the 185 Berger with an 11 inch twist barrel and about 44 grains of Varget if your throat is long enough for and OAL around 3.000". That's quite common load for the LR F-Class guys.
 
Well i am on the range in Pet In 2 weeks and i will put up paper targets at 1000m and see if there is any key shaped holes. There were none at 850m so i am curious to see if all the internet riflemen are correct. Keep in mind this will be done with 20yr old C3s with 1-12 rifling. Not to mention the 85,000 rounds they have thru them. I shall post pics!

Yes I do realize all this just wanted to point out they are not as bad as people say they are. I fully agree that there are better alternatives. The 168s I shot were factory if I were hand loading I would choose the 175 s or 185s ect. I will definately get my muzzle velocity next time Iam out.

Read through the log book that came with the rifle . It should have the round count on the current barrel, and when it was last replaced.

The round count books for those C3s have longggggggggg been abandoned. Ive been a sniper for 2 years and not one round for the C3s has been documented. They will be replaced next yr. We track all of the C14 AND C15 rounds religiously however.
 
You are most likely not going to see key holes but what you will see are elongated holes. The rounds seem to come in nose down. Are you using the ivi match or the norma stuff. Haven't played with the ivi yet but have seen these results with the norma stuff personally.
