I will be be buying some powder just for my 243 that I recently got..I will be using 100 gr Sierra ProHunters..From what I've read the 4350s,and IMR 4064 are very popular for this use,but some of the other powders look like they would be good also like that H 1000,and the Winchester 780 looks good,and there are more that look good,many are compressed loads though..I have IMR 4064,CFE223,and Reloader 15 on hand,but no 4350,and the 4064 is kinda spoken for because I use it in my 7mm08,and I will be using it in my 30-06..So if I'm gonna buy powder anyways just for this gun should I just buy extra 4064,or some 4350,or should I try something like that H 1000 powder,or some other powder any of you may suggest..I want accuracy,but I don't want to have to sacrifice too much velocity to get it.

Hey that h1000 is the bees knees, loaded to near Max on my 20" I'm at 2934 and close to 3000 on a 22" groups are phenomenal as I just put 3 sub moa on a 6" pumpkin at 500 yds doing a prohunter impact velocity test for another guy at 1800 fps. He's got a 7.62x39 so his goal was 200 yds. You'll not go wrong with that 1000 I'm showing no pressure signs and on my 4th loading per brass neck sizing only and just now need to FL size. At 100, my gal destroyed the 3/4" bull with 5 holes right before deer season.
 
Out of the powders mentioned I've only used 4064. It has the best groups out of all the powders I've tried.
 
Only ever used IMR4350 for 105 grain SP's. 5 grains difference won't matter.
Difference between the 'H' and the 'IMR' is negligible(100 grain Max loads are 2 grains more of IMR and 15 fps faster for the 'H'. Yeah.), but the two are not interchangeable.
H1000 moves a 100 grain bullet a bit faster than either 4350(Max load runs 3000 fps) but it also uses 7 grains more powder to get there. Try it. Your rifle may like it better. It's a case of working up the most accurate load and then buying the powder in bulk if you can.

I've never reloaded big scale enough for a few extra grains of powder to mean a lot to me,and I have always wondered why two powders by the same manufacturer stitting on the shelf are priced so much differently...Do they usually charge more for the powders that require less per load..
 
I never see Varget around,or I would have some..I always thought Reloader15 was about like Varget,but it never shows up in published data for 243 100 gr.

Check out alliant website, they'll show every load in .243 they recommend for each powder.

Thanks,I just took a look they recomend Reloader 23,and 26, the 26 recipe claims 3200 fps from a 24 inch barrel..I don't know how the accuracy would be though..It might be a good powder to expieriment with..I can probably get it at the local sporting goods store.

I've never found Varget to be that good in anything. However it's good point is it's hard to blow up a gun with it.

If you use 4064 in other guns & like it in this one as well then that would be a better reason to buy it in bulk & save a buck.

Nosler runs 17 and 25 with a Max load of 17 being accurate and mid range 25 accurate for their 24" Max 25 ran 3116 but accuracy for both powders tested ran 3033 for the 17 (60 fps slower than h1000) and 2988 for the 25. I've wondered about 19 or 22 but got too tickled with the 1000 to try em. Pushing the 95 partitions and btips out of my 20", it's scary fast and scary accurate too but takes 1 more gr of powder to do it hahahaha. Please let me know how the 22 works for you if you try it
 
Ive worked some with 7828 and its done pretty well, havent tried Retumbo. My goto powders are imr4831 and h4350, for the .243 mostly because they work pretty well and they are easy to get.
 
I have had a lot of success with both Varget and imr 4064 in 223, 22-250, 243, 308 & 30-06. There are other powders that work just as well in some calibers but those two seem to work in them all.
 
I have worked up loads with H1000, Accurate 4350, and Ramshot Hunter. All gave great results with 100 grain Hornaday SPBT pills but the Ramshot Hunter at 41.3 grains was my most accurate load in my NEF Handi Rifle.

Varget worked great in my 22-250 with 55 gr bullets

Others love it I know. The guy I gave it to is on this forum & lives somewhere in Ohio. He drove down to WV to get it & brought me some Dogtown bullets I still haven't got around to trying.

I can get under 1"@100 yards with it but I have powders that do better & cost me less that will work in my Lee disk powder measure that gets better groups. 4064 isn't even exactly my cup of tea for most of my loading. Even though it produced the best groups of everything I've loaded it doesn't do well in my Lee disk measure.

In my state I can now take my seasonal bag limit of deer all at the same time so I like little bullets with fast powder that doesn't have any recoil or report. I just start laying down deer without the others being altered. It makes return trips with other hunters easy since the other deer are never spooked from my shots. It's also nice to not have your ears ringing after a shot.
 
I think I'll just go ahead and buy a jug of H4350 ,I've been looking at the data on it and it looks like it's also a good powder for the 30-06,and the 7mm-08,even though I can't complain about my current load with IMR4064 for the 7-08..I had intended on using the 4064 for the 30-06,because I already have it on hand,but if I buy the H4350 I'll experiment with both..thanks for all the valuble advice everyone.
 
I'm currently using H414, mostly because a couple years ago it was the only powder I could find that was suitable. It does well enough for hunting. You may like it. H4350 may be hard to find in some areas, but that is supposed to work well. I myself will be trying H4350 soon. I am using he Sierra 100 grain as well.

imr 4064 and hybrid 100v both work well in my 243 shooting 100 gr nosler partitions (great on deer) and hornady 100 gr btsp.
 
Stick powders have proved best for accuracy. IMR4350 had a great track record with heavy bullets in 243's winning rifle matches. Varget is just one of the best powders for medium weight bullets in 308 Win cases if accuracy is paramount.

That's what produces best accurate ammo. If winning the race to the target is most important, there's several slower powders that'll push 'em out to fly dozens of fps faster. The bullets will need a bigger airport for them to all land on.

Life is full of compromises. Make ones best suited for your primary objective.
