I've been using IMR 4064 and was wondering if anyone has first-hand data or experience with using IMR 4350,especially if you have used both powders before. I'm interested in opinions on the load density,how your groups where setting up,etc. I just hate the idea of loading up 20 plus rounds and not see enough difference to matter. H&R Handi-Rifle (great little gun),95 grain Hornady SSTs,CCI 200 LRs,Win brass.

Have used Varget--didn't like it for density and groups never did settle in well. Have H414,but not sure it is worth looking at.

like Timothy I parted with my .243 some years ago, but in my old note-books I found a recipe of 40.5 gr. IMR4350 behind the 100gr. sierra boat-tail, remington brass, not one group was over .6 moa from a savage 110E. But that rifle shot just as well with 4831, and only opened up slightly, to about .8 moa at most, with 4064. Funny thing was, the best group it ever produced was with the Remington factory load, core-lokt 100gr, at .375 moa, but I couldn't reproduce that even with 3 more boxes from the same lot.
There is a dandy book you can get by several different authors called a reloader's manual. I got out mine by Hodgdon and find that you can put 40 gr. IMR 4350 behind a 100 gr. bullet. 95 gr. is close enough to use the same load. This particular manual did not list 4064, but others I have did. It only takes 36 gr. 4064 to get 2800 fps, so the load density would be a little more with 4350. After a little study, my conclusion is the change in powder probably won't gain much advantage. If you have the powder already, give it a try, you might learn something.I would do it, because I enjoy reloading and trying out something new. If it doesn't work, I go back to what I was using.
Yes, I had great luck with my .243 and 85 gr. Nosler Softpoints with IMR 4350. They don't make that bullet anymore, but my velocity was around 3000 fps and they were very accurate.
What worked in my rifle may not be the best for you--you might call Mike Daly at Hodgdon--he is the customer service guy and can answer any question you might have.
Hodgdon owns IMR and Winchester powders along with their own brand.
I don't have my .243 anymore so my experience is about 10 years old!
I use IMR 4350 exclusively in my .243. It shoots sub MOA groups with Sierra 85 grain BTHP bullets. I use CCI primers, Remington brass, and the rifle is an old 1962 Remington 700. I think it fills about 80 percent-ish of the case, but I can't really remember.
I used IMR 4350 in my 243 for years. I have a 243 Win in a Rem 700 rifle.
I don't recall using with a 95 gr. bullet. I used between 40 and 41 grains behind a 105gr Speer bullet. Accuracy was sub-MOA and was very consistant, but it was never my best load (though it was the load I almost exclusively used for hunting with my 243).
With 95 gr. Nosler ballistic tips and Partition bullets (sorry, never tried the SST in the 243 Win), my best load was using AA3100. My best accuracy came using between 43 and 44 grains and a magnum primer. When I dialed in that load, I could shoot 0.5 MOA at 100m all day long.
