300wm Favorite Powders?

[308win]

So today I intoduced a fellow shooter into long range. He is a lease hunter of mine that is very interested in long guns and ballistics. Currently he is shooting a REM700 Long Range chambered in 300wm using 150gr Sierra Game Kings. Good round for central Texas whitetails at short ranges, but as he discovered today, not so much at distance. He is new to reloading, but off to a good start. He used his own loads out to 855yrds with good results, but could be improved upon. Today's load was 71gr H4350 at COAL 3.340 averaging 3156fps ES 99 SD 29.5 (Labradar). We discussed the different aspects of reloading and lowering the ES/SD and bullet weight/ballistics.

I do not reload for the 300wm so I need powder suggestions for bullets in the 180 to 215gr range. He is on a budget so I'm looking for good terminal ballistics up close (inside 300) but still a viable option for steel out to 1000. Right now I have convinced him to keep his shots inside 300 and practice for 500 for game. He saw first hand what wind can do to a bullet past that.

Thank you for your suggestions

H1000 is usually the answer, at least it is for me. Not sure what the availability is for that powder it has been scarce

Thanks

H1000, Berger 215, and 300 WM are like peanut butter, jelly, and bread.

Gracias, gentlemen

I like RL23 for the 165gr class.

For bullets in the 180gr range RL22 works well, but for the last decade I have been shooting nothing but the 210gr VLD with H1000

All of the above are solid recommendations. You could add a nosler partition/accubond 180 and H4831.

Yep H1000 is the ticket but I also know some fellers that are using Retumbo and N570

 

[Rusty85]

I use H1000 and N570 with 205 elite hunters and 215 hybrids.

 

[Outdrmn]

7828 ssc and 215 hybrids.

I had good luck with H1000 and 7828 with berger 185 hvld, hornady 208 Amax, and 212 Eldx

I shot H-1000 forever and changed over to N-570.. It dropped my ES and SD and 570 shoots one hole now.. It does burn barrel more but, for a hunting gun the accuracy speaks for itself. H-1000 is a great powder but I just couldn't get the same numbers. 215 Berger and Fed 215 primer.

Always used IMR 7828 and got good results, but lately I tried RL-26. All I can say is wow, 175 gr bullets at over 3200 ft/sec from a 24" barrel. Great accuracy and superb velocity.

For 190-210gr bullets H1000 is great, not too slow and not too fast.
