Hey gang my 100 grain Nosler Partitions showed up.
So I only have IMR 4350 and H4350 for powder

So if some has load data for that criteria only can you please post ( Henry Long Ranger 10:1 twist).

Just though I could work up a load for that too now.

Thanks Jer

Cartridge          : .243 Win.
Bullet             : .243, 100, Nosler PART SP 35642
Useable Case Capaci: 49.323 grain H2O = 3.203 cm³
Cartridge O.A.L. L6: 2.710 inch = 68.83 mm
Barrel Length      : 22.0 inch = 558.8 mm
Powder             : IMR 4350

Thanks Dr Mike. I was just looking for a load that someone has tried and worked but I can use this too and work up one from it

I had a M70 XTR 243 Win that shot lights out with 70 gr and 100 gr bullets.
The 100 gr load was with 42.0 grs IMR4530, R-P brass and a CCI 200 primer.

Thanks I will maybe load a bit either side of that in small increments.

Did you play with seating them a bit deeper. I was told that could help with accuracy too.

I sold that rifle a long time ago so I don't have those details.
I would suggest you start low and work up. You can start .020" off the lands, magazine length permitting.

I think it's important to note that a load that is accurate in one rifle may not be accurate at all in another. So taking someone else's load and using it as your starting point isn't a very good way of finding what your rifle likes. You might, might get lucky. But you are more likely to not get lucky.

Really, there is no shortcut to working up your own load to see what your rifle likes. Accuracy is greatly influenced by the build details of the rifle, barrel harmonics, etc. If you're going to just pick a load and go with it, you're probably better off buying factory ammo. Just my .02.
