300 WBY Recipes
 

I am looking for a good hunting load for my 300 WBY, I will be shooting 165gr Hornady Interbonds. Anyone have input/suggestions?

Thanks in advance,

I haven't loaded that particular bullet in my .300 Weatherby Sako, but I have loaded some other 165 gr. bullets, so I'll list a couple loads that have worked for me:

Powder: H1000 91 grs. Max
Bullet: 165 gr. Hornady SST
Brass: Norma
Primer: Fed215M

There are faster loads, but that one was very accurate in my rifle.

Powder: RL22 84grs. max
Bullet: 168 gr. Barnes TSX
Brass: Norma
Primer: Fed215M

This load produced a little over 3300 fps and was plenty accurate.

I would definitely recommend trying IMR 7828 too. That powder has worked well with just about every bullet I've ever tried in my .300 Wby. It generally produces the best combination of velocity and accuracy. I've used it lately with the Barnes TSX and it works just as well as RL22, although it's just a tad slower.

As always, start your charges lower and work up. Your maximum load may be more or less than I listed since all rifles are different.

One more thing, I generally seat my bullets out as far as my magazine will allow, which is about 3.65". Seems to help in the accuracy department, although it's still well off the lands.

I'm sold on 7828 for this round now that MRP is no longer available. I tried to get the interbonds to shoot in my Mark V but was not successful. They wouldn't shoot better than 2moa. FYI, the 2 Mark Vs I've loaded for shot 165 hornady spire points extremely well (1/2" groups regularly). It also shot the 168 tsx well although at times, accuracy was inconsistent. It seems like with 7828, that 180s are generally easier to get good accuracy with. Others report good accuracy with RL22. My rifles have not shot well with it. I've heard reports that RL22 shoots better with standard primers. I've only tried magnum primers. My rifles have seemed to prefer flat base bullets over boattails (ballistic tips and game kings). This winter's reloading project is working up loads with 200g accubonds and partitions. Let us know how the Interbonds shoot--if they shoot well, they are probably the best premium bullet for the price.
