H-1000 in 243 win super dirty?

[Shawnba67]

I thought I'd give this powder a try and see if the barrel life might be extended. It didn't work out for me. Best accuracy was at 2950fps might as well shoot a dasher at that speed I did achieve 3030fps with Sierra 110 in my 30" tube @47.5gr well over book max.
Anyway this was a new x caliber barrel and this stuff is proving hard to clean out I shot a match with it and I bet I got 15 patchs through before I got an almost clean one
I alternate between wipe out foam over night and a few soaked in butchs of the evening over couple days time. Anyone else notice it being extra dirty? The wipe out only turned 1 patch blue so at least the coppers not sticking

I shoot 243win with H-1000 on occasion, (my main 243win powder is H-4831). And I have not noticed H-1000 to be any dirtier that H-4831. But now that I read your post I'll be more attentive next time I shoot with H-1k.
RL-25 is the dirtiest powder I shoot in the 243win.

I get really good barrel life with H-4831 and phenomenal accuracy, but I suspect that's because I'm not at the ragged edge of acceptable pressure, simply because best accuracy is with H-4831 is at lower pressures.
I'm shooting 105 / 107 grainers at 2,950 from a 26" tube. Win brass, 210m primer and 43 gr of H-4831. Even tho my load is 2 gr above Hodgdons Max, all my 243win barrels say Hodgdons data for this powder/bullet is way off. I tested up to 45.8 gr (4.8 gr above Hodgdon's MAX) with out any pressure.

Depending on the usual things.., maybe your 46 gr load is on the light side, leaving plenty of Unburned powder. The higher the pressure the more of the powder gets burned.
I'm assuming you could easily get 3,100+ fps in that 30" tube with H-1000 under those 110 smk's.

Some barrels take longer to settle that others and once they settle they clean easier and foul less.

My .243 X-Caliber barrel is 28". I shoot 105 Hornaday bthp with 49.9 grs. H1000, 3154 fps. Accurate and cleans up pretty easy. I have been shooting H1000 in my 6mm Competition Match barrels for years. Some lots of powder are slower than others, I've lived this. Of ALL THE H1000 I have burned, I have never been over pressured. Never popped a primer out.... even in Winchester brass that has been loaded over 20 times.

i do not have experience with H1000, but I was breaking in a Tikka CTR in 6.5 Creedmoor with some Hornady Whitetail 129 gr. because it was cheap. I found it to be dirty in my rifle and hard to clean. I commented on this to someone and they said that the dirty and hard to clean was probably due to the barrel being new. He was right and after about 100 rounds it got much easier to clean. Plus it seems to get easier as time goes by.

Give it 150-200 rounds and see if it speeds up. Sometimes they and sometimes they don't...

H-1000, I'm at 47gr in a 6MMSLR with PPU cases, 48gr with Win cases, Brux barrel that took a .2355 (tight) pilot for the reamer. No issues with burning dirty here.

Don how are you getting 49.9 grs of H-1000 in a .243 case?

slurpin dog,
Using a long home made drop tube. 50 gns. with a 105 Amax.
Donnie and I have similar set-ups.

Back to the OP's original point....loading 48.8gr of H1000 in front of BR2 primers I get quite a bit of unburned powder in my 30" barrel. The accuracy is very good but?? Maybe magnum primers??

I shot some Hornady 105 BTHPs with 50 grs H1000 the other day in my steel plate banging gun and it really shot well,,from a 100 yard zero it took 21.7 MOA elevation to get on at 1,000 yards,,the 10 inch plate was no problem and my 5.5x8.5 inch head shot plate made 5 hits in a row after I got the exact wind hold figured out,,as the 105 Hornady`s are 98$ per 500 and I have a bunch of H1000 from my 338 days I will be shooting a bunch of that load and saving the high $$ VLDs for more serious stuff than steel plate shooting,,

^^^, Ron this is how it's done.

I use LRM primers also. CCI and Tula.
