Favourite 300WM load

[TrevorMack]

Brand new to reloading looking too see what everyone likes for their 300 win mags. Been doing lots of reading but looking for as many inputs as I can get.

My immediate question is "For what?" I use my .300 for "bigger than deer", and I shoot 200 grain Partitions over H1000. Does that suit your intended uses? What you are doing with a particular cartridge is an important part of the decision about how to load it.

H1000 behind 200 grain bullets as well. Almost always Partitions as I am a hunter more than a paper puncher.

Main use will be hunting but also to play around with Kong range. I'm not getting serious into long range just dabbling in it see what I can do. So my main thing will be hunting with it.

Max load of Reloader 22 and 180 accubonds in ��MY��rifle, all others are different

In my commercial Mauser action rifle, What is the most accurate load is 70 grs of IMR-4350 pushing a 180 gr Nosler Partition PP.

RL 22 and 180gr Nosler Accubonds are a great combo.

IMR 4831 or Norma MRP and 180 Partitions, H1000 and 200 Partitions.

My son's 300wsm T3 Tikka will shoot 180 grain Speer SPBT into -.25 inch five shot groups under good conditions at 100 and half inch at 200 with IMR 4350.

But we first had to start low and increase powder in .2 grain increments until we could find the point where the group really tightened up. That took a lot of time and work but was really worth the effort. In my own rifles I have found that this approach is needed for each of them, and after we found what each rifle preferred it was interesting to discover how much several were different than the rest in this regard. My son wanted to use Barnes 180 grain TTSX in his Tikka and the load for it as well as the powder was way different than for the Speers. The resulting tiny groups were not that different.

Now I just have to convince him to spend more on a really good scope in place of his Zeiss with its 3.5 inches of eye relief for his sheep hunting.

imr 4831 with 180gr scirocco 2's, and h1000 with 220gr partitions. both are very accurate.

IMR 4350 behind 165 Nosler Balistic tip.

I use IMR4831 and 180 gr SST's. 4350 worked good as well. H1000 and 4831 worked well on 200's. I settled on 4831 and 180gr.
