75gr. Vmax w/ H4350 in .243 Win.

CanusLatransSnpr

Hey all :)! I've been looking in my Hodgdon manual and I don't see any load data for a 75gr. bullet and H4350 powder. I was just curious if anyone has a Hornady manual and could see if there's any load data for the 75gr. Vmax and H4350? I have H414, IMR40007SSC, IMR4064, H380, and IMR4320 on hand but, I would like to use H4350 if I could. Just for the greater temp. stability since I'll be working up loads in the colder climate!

Thanks,
Mike

I realize that it might be convenient to use what you already have on hand, but H4350 probably isn't your best choice for that cartridge and bullet combo.

I'd either start looking at other powders, or changing your bullet weight.

Otherwise you are going to be compromising, and not getting your best results. It's "economy" of a bad sort going that route.
 
Here you go.
Hornady's 8th edition, 243 win, 75 gr bullets - H4350. Starting load is 42.9grs yielding 3100 fps and the max load is 46.7 grs yielding 3400 fps. They used a Federal 210 primer; 24" barrel; 1 in 10" twist.
I've had my best accuracy with the 243 using IMR 4350. Hope this helps,
Gary
 
Gary, thanks for the info and if I had any I4350 I would be open minded to trying it!

Coldbore, I appreciate your concern and as I have stated I have other powders at my disposal but, I want the greater temp. stability that the extreme extruded line of powders offers. I'm certain H414 would be a better suited powder and performed great shooting 70gr. Speer TNTs in this same rifle but, the 75gr. Vmax is a considerably longer bullet and I think the slower H4350 would be a good fit! Maybe I'm wrong? H4350 has worked well for me before with the 87 Vmax and everything I've read states that H4350 is a great powder for the .243 Win. I don't want any pissing matches, just going from personal experience and what I've read!

Thanks,
Mike
 
CLS, Ran your request through QL using the default settings and I got numbers mirroring Gary's. Start at about 43Gr's and work up slowly,, I really think you'll find a load that's adequate with suitable velocities.

Don't confuse powders with twist rate. A "longer" bullet needs a faster twist, not necessarily so with the powder. How much of that length is in actual bearing surface? Still, think more "weight" instead of "length" when dealing with powders. There are exceptions of course (design shapes outside of the "norms").

H4350 has worked well for me before with the 87 Vmax and everything I've read states that H4350 is a great powder for the .243 Win.

It is, and like you have found, tends to work better with the heavier bullets, not the mid-weight and lighter bullets.

I'm not looking for one either. ??? Just trying to help, by saying that although it may "work", I don't think you're going to get your best results with that combo.
 
Got out and did some shooting yesterday and really wasn't able to figure anything out. I have a new scope base and ring setup, 20 moa rail w/ burris signature zee rings, and ran out of down moa and my bullets were hitting 7.5 moa high @ 200! I have to order some inserts with moa loaded into them and start over again!

Chuckhunter, I appreciate you running the numbers through quickload to verify the info that Gary had given me!

Coldbore, I'm well aware that heavier bullets require more twist, which I have sufficient twist to shoot the 75s, and that heavier bullets tend to favor slower burning powders! For 80gr. and heavier you see H4350 being recommended as a powder and seeing that the 75gr. Vmax is but 5gr. lighter my thoughts were why wouldn't it work? I don't have any "local" suppliers of powder that have much of an inventory to choose from so I'm going with what I have! If I were shooting in warmer temps. year round, I wouldn't hesitate to use H414 but that isn't the situation! I appreciate your help and your concern but, I think I'll get what I'm looking for with this powder! It doesn't have to shoot the fastest it just has to shoot consistent! As far as the pissing match thing goes, I have seen quite a few of those on here recently and was just trying to avoid it is all :)!

Thanks,
Mike

Agreed 100%, and more.

I've always said I'll gladly give up 100 FPS in exchange for tighter groups. Ain't a target or groundhog or deer will ever notice the difference in the slower bullet, but they/I will notice a bad hit or flyer on the paper.

My wife can usually sense when one is getting close, and pulls my computer access chit when that happens! :P
 
Been shooting and loading the 243 for over 40 years. Now that doesn't make me an expert, just fairly experienced with the cartridge. Here's what I've learn:

IMR 4350 is an excellent choice for the heavier bullets in this cartridge, (i.e. 90 grain and above). Has worked in every 243 I've own over the years for these bullet weights.

I've had success using IMR 4350 with both 80, 85, and 87 grain bullets in some rifles, others prefer IMR 4064 or Varget.

With the lighter bullets, 70 and 75 I've had my best success with IMR 4064 and Varget.

Same here except I use H4350.
 
I have been shooting the 75 gr. Hornady HP for years with 46 grains of 4350, surplus powder, with CCI primers in a Sako HB. Winchester cases. Best accuracy and runs along at 3350. Accuracy below and above was terrible. But this load has been consistently excellent.
 
I have had great luck with h4831 powder with the 75 grain bullets which I use a lot of these days.
 
Hodgdon, by omitting powders as popular as the 4350s from their 243 Win 75-gr bullet data, are trying to tell you something. They found 14 other powders "in the family" which are significantly better than 4350

Hodgon also omitted Benchmark for the 75 vmax. But try. 36.5 gr Benchmark , 210 primer several people say load is acccurate. Shoots.60 moa in an old savage for me
