[reloadxx]

I am going to do some loads for one of my 243 going to try and use 100 grain nosler partition I have a couple of pounds of h4350 anyone have a load they care to share with this particular bullets and powder ? I have a half a boxof the nosler partition would like to see if I can get something close before I buy more bullets since they are hard to find

A good friend, many years ago went down the 243/100 gr Partition road, tried everything without much luck till he tried IMR 7828.

I use 90gr Accubonds in my 243, but IMR 4350 and IMR 4831 both shoot well. Don't be afraid to go with a slower burning powder.

I use 36.0 gr of AA 4350 and 100 gr partitions in my daughter's Remington .243. it's a real picky load tho, .3 up or down and it'll group outside of an inch at 100.

No experience with that powder in any caliber just yet. I have some for 140's in our 6.5

Heavy for caliber bullets like slower burning powders (a general rule). There are other powders than H4350-RL19 and IMR7828

IMR7828 in the 243 is an absolute perfect load for the 100 and 105 partitions. Great velocity and accuracy. And IMR7828 is generally available

Our 243 is a 1985-era Remington 700 ADL. This rifle has a long throat and bullets were loaded that way as IMR7828 frequently is a compressed charge. On the Tejon Ranch in Southern Califiornia we killed 8 or 9 deer at distances ranging from 40 to 140 yards all with the 100 gr partition and IMR7828.

This is one rifle I have not yet been successful in converting to Accubonds. The primary reason is accuracy with the heavier partitions and multiple powders that produce the accuracy and velocity I want.

So, my suggestion is if at all possible get hold of some IMR7828.
Here is Hodgdon's numbers on the 100 and notice the max load achieves my objective of 3,000 FPS.

I use imr4350 for 100 grain hornady btsp in 243. Without looking in my log book, thinking the sweet spot for the two rifles I load for was around 42 grains.

My wife and youngest daughter have probably killed a couple dozen deer with my 243 handloads, I think they have had maybe one or two make it more than 50 yards, and those didn't go far.
