This will be my first time to load for the little .243 for my Remington MoHawk 600 and would like to know your thoughts on the best powder to use for the heavy BOOLITS for Deer? Thank You for any help this great forum can give.![]()

Cliff,
For 100gr jacketed bullets(usually Sierra SBT's),I've used IMR-4831 the most.I've also used H-4831 and H-450(discontinued).
I've recently played with some Hornady 95gr SST's with IMR-7828.Never shot any deer with those yet but they are very accurate.

The problem with the slow burners in this case/bore size is that the powder needs to have that chemical used to maintain burn throughout the temperature range. I went through this just last time it was 75 degrees or so with 100 grain BULLETS. Pressure was just perfect using 7828 by the base expansion measurement. Shot the same load again at about 40 degrees, and you could have cooked an egg in the primer cavity. We're talking at least a 10K cup drop. I searched the boards looking for this characteristic in other powders. RL22 is one of the worst offenders, it appears. Maybe the Aussie 4831 powder has that chemical required as does Varget has for sure. To sum this up, I would use 4350 at the slowest and sacrifice some velocity at the higher temps next time around. In other words, use a faster power, and a considerably faster one for BOOLITS. ... felix

100 grain jacketed IMR 4831 in .243---between my son in law,nephew,grandson and myself several pickup loads of deer and I don't recall any that were not one shot.
I've been using 12.0 grains of 2400 with the RCBS 95 grain spitzer casting with fine results. Velocity runs about 1650-1700 FPS, and accuracy is first-rate........MANY 1-1/8" to 1-1/4" 5-shot groups at 100 yards. These also whack ground squirrels and jackrabbits in no uncertain terms.
I don't paint bullets. I like Black Rifle Coffee. Sacred cows are always fair game. California is to the United States what Syria is to Russia and North Korea is to China/South Korea/Japan--a Hermit Kingdom detached from the real world and led by delusional maniacs, an economic and social basket case sustained by "foreign" aid so as to not lose military bases.
I have used 100 gr Hornadays with IMR 4350, AA & IMR4064 and both 4831. I get the best accuracy with IMR 4831 though all are close. I have yet to run low enough on it to try the short cut stuff. Gianni

Best 100gr rcbs cast load 12.5gr 2400![]()
I picked up some Hornady 95Gr SST BOOLITS. But reloading data for them is pretty much nill and Hornady will be closed till the Jan 5th lol. Would someone have load data for this BOOLIT with IMR-4350?
Thank You for all the help.![]()

BTW Cliffy,it's BULLET when ya talk about Hornady 95Gr SST's![]()

Do NOT use 4350 with BOOLITS! ... felix

IMR4350 and IMR4320 and IMR3031 are good with 100gr jacketed for the 243.
H 4831 for 100 gr. jacketed.
Again lol I picked up some Hornady 95Gr SST BOOLITS. But reloading data for them is pretty much nill and Hornady will be closed till the Jan 5th lol. Would someone have load data for this Bullit with IMR-4350?
The Hodgdon site does not have load info for this bullet that is why I brought the ? here
Thank You for all the help.
And a Happy New Year to you and yours, Missionary!
I've used Taracorp alloy for most of my rifle boolits for a long time. This is 92/6/2, or half Lino/half unalloyed lead. I just ran a brush and Hoppe's with patches through my Rem 788's bore after about 600 rounds of this load, and there were only a few tiny 'sparkles' on the patches visible in strong light. As a practical matter, there was zero leading. Accuracy had fallen off a bit, and I think lube deposits were starting to build up in some manner (I'm using Javelina Alox). If the wind would die down some, I'll see if this clean-out eliminated the flyer issue for me. Few things ruin a range day like ONE flyer 1.5" out at 2 o'clock when nine other hits make a chrysanthemum of 3/4" CTC @ 100 yards.
I'll also be trying NSP-64's recommendation of 12.5 grains x 2400 in 243 and 250 Savage. The RCBS Cast Bullet Manual gives data using 2400 powder at 13.0 grains (1735 FPS) to 15.0 grains (1987 FPS); (pp. 51). 12.0 grains runs just under 1700 FPS for me, so there may be some credence to the idea that Alliant 2400 powder has been re-formulated since the 1986 publication of the Manual.
Kudos and thanks again to Carpetman for the samples of the RCBS 95 SP that proved so accurate in my 788. Few cast boolit ventures with rifles have been as satisfying as the accuracy and enjoyment of the caliber I get from these home-poured smallbore castings in the 243.

Rugerman1 you kill me lol.
I don't believe Rugerman1's post was in jest. It appears you do not have a reloading manual(?). You can "Google" most of the manufacturers and get some loading data. The best "all around" manual is the Lyman 48th Edition Reloading handbook. It has jacketed and cast bullet information and data. I'd suggest you get at least that one.
Data for a 100 gr Hornady BTSP with IMR 4350 from that manual;
Start; 35.5 gr
Max; 39.5 gr
This data should be a good place to start working up your load. If you do not know how to "work up a load" then please get the Lyman Reloading Handbook and read it. Please do not just "go" with a load as that can be dangerous.
With jacketed bullets I've not found 4350 to be the best powder with the heavier bullets. I prefer H4831SC and use it exclusively in the .243 with 100 gr hornady SPBTs.
Sad to say I've not shot any cast in the .243 so I will defer to those who have on that subject.

I would think, Larry, that Hodgdon's 4831, sc, ssc, would be the best speed, especially ASSUMING that flavor (Aussie?) has that chemical(s) which keeps ignition consistent enough throughout the environmental temp range for all hunting conditions. Hopefully, they start using those ignition chemicals for all their powders, IMR, and WHOEVER. ... felix

Larry yes I have both the Lyman 48 and the new 49th edition. But there is no Hornady .243 6mm 95Gr SST load info. Also on the Hodgdon site there is no load info for this bullet as well. And I also know I can order the Hornady reloading book as well. And call Hornady directly after they reopen on Jan 5th.
I was just in hope that someone on this site where people tend to load just a bit would maybe have the information on hand.
Thank You for the thoughts.
