Eddybo, It is said that you are the .243 guru. Well I have a .243 problem. I have a Remington Model Seven with an 18" barrel. Scoped with a 6x Leupold. I want to shoot 100gr Nosler partitions for whitetail. I happen to have about 500 100gr Nosler partitions in 6mm and 6 pounds of IMR3031. I've used powder weights all around the recommended 35gr of 3031. At 50 yards I am shooting a 3-4" group at 50 yards.
I can put 80 grain hornady factory loads through it and it puts all rounds through the same hole at 50 yards. I believe the barrel has a 1:9.2 twist. Is the barrel too short to stabilize the longer bullets. I hunted with an old Remington Mohawk Model 6 many years ago, I dropped two mulies at 200 yards with it, one shot each. So I had to have me a .243
The Mohawk had an 18" barrel also. Is the barrel too short. Given the price and scarcity of reloading components I'd like to be able to use the components that I have.

I would think that a 1:9 would be plenty to stabilize a 100g NP regardless of barrell length. I had a difficult time getting the 100NP to even shoot out of mine with a 24" tube. The best powders I found were Re15 & IMR 4350. However, I settled for an 85g TSX. I dont know much about 3031 but I would increase my charge gradually and see if it tightens up. If it doesnt then I would think that rules out a stabilization problem. However, EB has forgot more than I will ever know.

yeah eddybo posts on msoutdoors a good bit these days.

Have you tried different seating depths? I've never played with NPs but the chamber on your rifle might be longer and need a little less jump.

You can check the twist of a barrel with a cleaning rod. Measure out 12" on it. Put a mark perpendicular(sp?) to these measuring marks. Put a good tight patch on it. Then pull the rod from the top mark to the bottom mark and count how many rounds it makes in that 12"

If you have any different powders try that too.

I've never messed with any 243s myself.

Your 9.25 twist and short barrel are probably not spinning the 100gr bullets well enough. You could get away with it if you had a 22" or longer barrel. I would try some 90gr partitions or accubonds if I was you. You shouldn't have a problem selling the 100gr partitions as hard as bullets are to come by these days.

That is why I suggested speeding the bullet up to see what happens. By speeding it up you can accomplish almost the same rpm's as with a longer barrell with same twist. I just cant imagine that not being enough twist for a small flat based bullet regardless of length.
