Difference between H4350 and Reloader 26

[Local Loader]

I'm unsure about the behavior difference between H4350 and Reloader 26? Anyone have experience with both in same caliber and weights?

RL26 is much slower burning than H4350 and seems to be at its best, and gets higher velocity, in larger cases vs bore, using heavy for caliber bullets. For example, I can get 3000 fps in a 270 with 150gr bullets while I can barely get to 2750 fps using the same bullet with H4350. Same with the 7mm Rem Mag and 160gr bullets. 3000 fps is easily doable with RL26 vs 2750 with H4350.

If using lighter weight bullets in those same cartridges, I would use H4350.

I'm trying to go with more heavier bullets 180gr to 220gr. So I'm still trying to figure out which how each behaves.

Which cartridge? If there is enough case capacity, RL26 would be the better of the two. If a standard case like 30-06, I'd likely look at H4831 or RL22.

I'm using a 300 win mag.

RL26 would be my choice with that cartridge and those bullet weights.

Got any experience with H1000, US869, WC 760, RL-17, magpro or Retumbo? Lol.

I do like the velocity it gives but seems it uses more per load for same fps. Is it cleaner burning?

300 winmag.
Im running 7821 stmk 195gr. At 2950fps. I'm running the 2nd node diwn from max. The upper node was 3050fps. 1/2 moa

US869 and Retumbo will be too slow. You'll probably find satisfactory performance with H1000 or Magpro
RL17 and 760 are too fast burning for the heavies.

It may require more, but that's expected from a slower burning powder. The fact you can fill more of the case without spiking pressure is a good thing. It seems to burn pretty clean.

Hey there. I know your post is from November but thought I'd let you know about a load I use in my Remington 700 .300 Win Mag.
175gn Sierra BTHP
Remington 91/2 Mag Primer
86gn US869.
Yes US869 isn't that versatile as it is a bit too slow for lighter weight bullets but I am very happy with it using the 175gn.
At 100yds I'm making a clover leaf hole. Only thing I've started doing differently is I now use a LEE Factory Crimp Die and I've also had a muzzle brake fitted.

Meant to add the load is slightly compressed giving good load density. Pressure is good primers aren't flattened with the edges still staying slightly rounded.
