I just answered your first thread before I saw this one. (Dunmore, nice town)
Hodgdon has an online data site with extensive load data for all Hodgdon/ IMR/ Winchester powders including H4350.
I highly recommend you check the link and follow their data without going over it.
You don't want an overpressure problem in a 9 year old's rifle.
Cartridge Loads - Hodgdon Reloading Data Center - data.hodgdon.com
You can also contact Speer and ask them about that combination, they are usually very helpful...

i have checked the site you said they dont list the sierra 100 gr spitzer that i have i have h4350 they list imr 4350 not h4350 for that bullet
well welcome to the forum and welcome from Oregon .I always used IMR 4350 with my 243s somewhere around 42 grains with a 95 gr nosler balistictip
i guess i have to wait untill i find some imr4350 to load up the 243 i,ll use h 4350in the 3006 loads or 7mm mag loads i have 400 sierra 100gr heads to use up like to load them for a 243 good shooting bullet i have alot of sierra to use up i now you can use h4350 in a 243 but not with the sierra 100 gr i went to the irm hodgon site they list for other bullets with the powder i want to use i wounder why they dont use the sierra bullet 100 gr they list speer nosler hornady not sierra with h4350
back in the 90s i did a lot of loading for the 243 win. with a lot of powders and projectiles. the best powder i came up with was imr 4831 i use it today for my wifes model 600 mohawk remington with a 95 gr. berger vld 44 gr. will produce one hole groups.

243 Winchester is one of my favorite rifles that I load for and hunt with. I've used both Sierra Spitzer Gameking and Prohunter 100 grain over 40.0 grains of H-4350 and 42.0 grains of IMR-4350. Both are DRT on whitetails and extremely accurate. Any 100 grain .243 bullet loaded with H-4350 is an excellent combination. If you follow Hodgdon's minimum to maximum load recommendation; whether you are using a 100 grain Sierra, Speer, Hornady, Nosler, or Remington you should not have any problems. I've used the above recipes' with various brands of bullets, either 100 grain boatail or flatbase, without a problem. If you contact either Sierra or Hodgdon I would imagine they will tell you the same. Let us know how it works out.
