OK....one more time. 470 nitro, 55-60 grains of 5744 with a 215 primer. NO FILLER NEEDED??? There is A LOT of airspace in those cases. Is this OK? I'm loading the 400 gr Hornady pistol bullet for fun....but that airspace is a little scary. I know I need the filler for the RL 15 loads...but not these? Would somebody confirm this to the new 470 reloader. Thanks.

Does that particular load regulate and shoot to point-of-aim? I think with close to 1/2" air space, I'd use a filler and not take any chances. You must have gotten lucky in that 5744 has been hard to come by since all the cast shooters have discovered that it is great for that and reduced loads.

Am using 40 to 45 grains of 5744 behing a 500 grain FPGC cast bullet ... lots of air space, but not problems and VERY accurate.

475...don't know if it regulates or not..I just loaded up a half-dozen of each at 55 gr and 57 gr to see. I had heard before that no filler was needed...but I wanted confirmation. Grafs always seems to have the 5744.
Mike...thanks for the info. I thought that was the case but wasn't sure. I'm loading the 400 gr Hornady pistol bullets....I'll see what happens as far as regulation and velocity. I'm also loading the 500 gr Woodleighs with RL 15 and foam fillers...trying to duplicate that good but EXPENSIVE Federal stuff.

Thanks, guys...take care.

AA-5744 does not need any fillers with reduced loads. AA e-mailed that I could go as low as 30gr in my Lott without any problems. They also told me that the only negative with this powder is that if you go to low you will have some unburned powder in the barrel.

HK...thanks for the reply. I will post the results of my loads...I have a chrono and am looking for a good practice load to mix in with the normal big stuff.

HK,
You are mistaken, the 470 case is much larger than a 458 Lott and it definatly requires a filler least you will ring your chamber at best and rip a barrel at worst....The world of double rifles is a whole nuther ballgame....Always use a filler with any powder that will not basically fill the N.E. cases to the bottom of the bullet, never leave an air space in a double rifle...

45 grs. of 5744 and a good dacron filler with a 500 gr. bullet will regulate to the same POI that 108 grs. of IMR4831 will in most .470s...

I have not loaded the lighter bullets, but absolutly use plenty of filler and too much is better than too little filler.

Ray,

I got the following information from Butch Searcy early on in my .470 loading after providing him with my rifles serial number:



"Full Power Loads:

IMR 4831 powder = 108 grs.
Federal 215 primers only
500 gr. Woodliegh bullets

OR

90 grs. RL-15
wad over powder- I use 3/8" styrofoam
Federal 215 primers only
500 gr. Woodliegh bullets
Do not try and reload your cartridges more than two or three times. You will have case head separations.

Light loads:

XMP 5744 powder = 45 grs. no overpowder wad needed
Federal 215 Primers
500 gr bullets
1400fps"

I imagine there are several factors here not the least of which is the strength of Butch's modern doubles.

Well....the confusion starts. My rifle is not a Searcy, but a new Merkle. I THOUGHT that the lighter loads using 5744 didn't need a filler. Anybody have a DEFINITIVE, ie fired these loads w/o problems? I don't want to blow my new double up, but now will need to pull the bullets and put the filler in if needed. Don't want to create havoc, but if anybody has fired the loads similar to what I've loaded...without the filler, I'm all ears. Thanks, as always for the opinions.

Gary B.

Well I have been shooting doubles for awhile and I will never fire a load with 5744 or RL 15 without a filler...I also shoot a Searcy..I have simply seen too many ringed chambers from no fillers....No airspace for me, but for those who insist on no fillers, be my guest...

Ray, the maker of your rifle does not think you need a filler with XMP5744. I have used it without a filler in 470's and in a .500 with no problems.

Keith,
You can go very low with this powder.
There is no danger to only negative is that at some point you will
experience unburnt powder.
We suggest as low as 30grains.
