Reloading 243

[7mm08Fan]

One of my good friends is wanting to load for his sons 243 using Sierra game king 85 gr what are the best powders for this type of load

 

[ButterBean]

Varget

 

[Sockeye66]

My top powder for accuracy and speed with that bullet was with Hybrid 100v, and I will add that the 85gr BTHP Sierra GK is an excellent bullet for deer IME.

Thanks honestly I haven't heard of that powder I'll look gor it I have imr 4831 4895 6.5 staball 4064 I have others for mostly magnum calibers

 

[Sockeye66]

Of the powders you listed, my first option would be imr 4831, but the others you listed could work well also, along with any of the 4350's and as @ButterBean stated, Varget.

 

[GLTaylor]

Also StaBall 6.5.

 

[Hudge76]

My favorite powder in .243 so far is Hunter. There are plenty of good powders for that weight of bullet though, H100V, Varget, IMR4064, H4895, the list is long.

4895 works in a lot of cartridges. Of the powders you listed I've gotten the best results with Stabil 6.5 . The 85 Sierra is my go to bullet in the .243 when I can find them . Which has been about 3 years.

Oh man there's sooooooo many powders that would work well with that bullet weight in that cartridge. One that has promise that goes overlooked by many is Hodgdon Leverevolution. I had great results with it in my 243 shooting 75 grainers BUT they were old school 75 grain Barnes x bullets, probably pressure up at least as fast if not faster than an 85 grain cup and core even after I HBN treat them.

I like using IMR4350

243 Winchester

IMR4350 with Sierra #1530 85 gr hpbt. BR2 primer. Win or Rem brass. Work up to 42.0 grs. Some guns may like a little more powder, 42.5, to 43.0 maximum.

85g Speer btsp with R#19 & IMR 4831, Win brass is all over 3400 fps in a 26" barrel. The 85g Speer btsp is a deer bullet, not a varmint bullet with a pretty good BC. HV100 would be my second choice with speed and accuracy. Varget = IMR 4064 worked extremely well, but 200 fps slower than the above loads. IMR and H4350s worked very well. H and IMR 4895 are stellar, just not the speed of 19, IMR 4831, and HV100.

You rarely ever hear it mentioned, but the Barnes 80g TTSX is one heck of a deer and hog bullet and HV100 gives blistering speed with accuracy jumping .050 from the lands.

I got better penetration with the 85g Speer vs either of the Sierra 85's.

Thanks honestly I haven't heard of that powder I'll look gor it I have imr 4831 4895 6.5 staball 4064 I have others for mostly magnum calibers

From your list in order of precedence, IMR 4831, 4895, 4064, Staball 6.5, but YMMV.

Alliant Reloader 15 or Reloader 16 are both good picks and it's $10 bucks off a pound at Midway USA.
