I'm looking for a starting load using 168 gr ct bullets and h1000 in a 300 win mag.
I have asked on the Nosler board a bunch, but not the Hodgon board. If they are a responsive as Nosler, then: <font color="red"> </font>

I am loading H-1000 with a 168 TSX.Great load!Called and talked to a Hodgdon tech and he says my load should be completely safe and within their pressure limits.I have worked up to 83 grs.If your careful and have a good chronograph you can probably do the same with the 168 CT.
Start at 81 grains of H-1000 as this is what I am shooting behind the 180 TXS it is the most consistent load that I have shot with an estreme spread of 5 fps.
I have a maximum load of 81.5 grain using Hornady 180 BTSP so you could start with that and work your way up. H-1000 is very stable powder. It's my favorite powder for my 300 Winchester Model 70 Laredo.
I am loading 81.5 gr H1000 with 175 gr Berger VLDs and SMKs currently. I loaded up to 83 gr without pressure in my rifle. Use those loads at your own risk. OAL is 3.660"
Is there a problem with REL 22 on heavier bullets? It seems to be popular with 300 win mag users, but not many recipes with the 180 grain plus bullets.
Check out reloadersnest.com. There are quite a few loads on there for bullets over 180gn and RL-22.
A pretty "standard" RL 22 load with 180's is around 75 grains and for 200's is around 73 or so. If you search around the internet youll see these loads come up again and again. Ive shot less than MOA with these loads out to 1000yds, BUT Im trying to find another powder as you are.
Ive read alot of bad stuff about temperature variations and lot-lot variations with RL22 so Ive been testing H1000(79.5), Ramshot Magnum(79.0) and N165(73.0). Im still in the process of testing, and have had good results with all 3 but need to test @ 600-1000yds. 72.0 N165 with the 210 Berger was a standard load for the AMU for quite a few years FWIW. With RL 22 I was getting 3033fps with a 200, and have only got from 2850-2950 with the other powders listed above, with good accuracy. Now dont get me wrong, speed isnt everything, Id rather have a consistent load at less velocity than a faster one that isnt consistent across a wide range of conditions. I compared 2850fps versus 2950fps on JBM and it only came out to a 6" difference in wind drift @ 1000 yds for a full value 10mph wind. If you want Ill post my results when I get finished.
Thanks Jim. Post away. I haven't started yet and have some re22 left.
DB33- I HAVE SHOT THE 168 CBT IN TWO GUNS WITH 71 AND 72 GRAINS OF I-4350. 1/2" GROUPS AVG... I HAVE NOT USED h-1000. I USE RE-22 WITH 210 BERGERS. I MAY TRY H-4831 OR h-1000 THE 210'S. NO NEED TO MESS WITH MY I-4350 LOAD AND THE 168 CBT'S THOUGH IT IS GOOD ENOUGH. RON
