9.3x64 Brenneke loads

[tunatoy76]

Just having a 9.3x64 finished on a FN98, looking for some feedback on the 250 gr accubonds on larger deer and feral pigs. Does anyone now of or have published data for the 270 gr Speer in the Brenneke as a want to use them as cheap loads for practice and getting used to the new rifle.
Any help appreciated, thanks Shawn

Welcome aboard Shawn. I’d imagine Mike will be along and pass you his loads for the Brenneke. I think he’s had some great results with the 250 AccuBond.

Awesome cartridge. Hope you’re able to put a picture or two up of the rifle.

Thanks for the welcome and will do

Welcome aboard, Shawn. This is one of my favourite cartridges.

My "go to" load consist of RWS case, R 9.5M primer, Nosler 250 grain AB, and a charge of 67.0 grains of RL15. Solid sub-MOA load (~0.42 inches) launched at 2700 fps. This load is sufficient for about anything I would wish to hunt in NA. Consequently, it is the load that I'm most likely to have with me when I carry this rifle.

I've had good success with a load consisting of RWS case, R 9.5M primer, Nosler 286 grain PT, and 66.0 grains of RL15. Again, sub-MOA load launched at 2600 fps.

A similar load is built of RWS case, CCI 250 primer, 286 grain PT, and a charge of 78.5 grains of RL22. Velocity of this load is just a skosh below 2600 fps.

I had good success with a load defined by RWS case, CCI 250 primer, 300 grain Swift A-Frame and 52.5 grains of IMR 4064. Velocity was ~2450 fps and accuracy was 0.66 inches. This is a fine cartridge that deserves far more recognition on this side of the pond.

Again, glad to have you posting.

Welcome to the forum Shawn, glad DrMike was able to see your post and give you some data. There may be one or two others on here that shoot the 9.3x64 and rounds similar to these are quite popular here so you have come to the right place. When I was a guide the outfitter I worked for used a 9.3x64 as his back up gun for grizzlies with good success.

Thanks for the welcome and load info. Powder availability is my biggest issue with most loads. I currently have AR2208/Varget, AR2209/H4350 and Win760/H414. I live in South East Queensland Australia so powder can't be shipped and it's over a two hour drive to get it. I realize there may be better powders but am stuck with what I have at the moment.
Thanks Shawn

Any of these powders would give you some pretty hefty bang for your buck. Let us know when you get your rifle and how the load development works out for you.

Any of these powders would give you some pretty hefty bang for your buck. Let us know when you get your rifle and how the load development works out for you.

Is it possible to get load's for the 270 grain Speer?
The accubonds run at $2.50 each, vs 80c for the speers, I hope to put a few practice shots through before working up loads with the accubonds. I shoot accubonds in a 257 Roberts and 30/06 with excellent accuracy and results on deer and assume they will do the same in the 9.3, just to expensive for targets.
Thanks Shawn

Welcome!
While my 9.3 is the 62mm version, I too have bought some of those 270gr Speer Hot Cor to develop a heavier load for my rifle.
Have been impressed with their expansion and weight retention by those here who have done the testing on water jugs with them.
Have always had good performance with them in my 358 Win on big game, so am looking forward to using them in the 9.3x62.

Really like the accuracy and felt recoil that the 250gr AB is giving is giving in my rifle with the Nosler factory ammo. Definitely less than what my 338 Win Mag produced with 250gr loads.

I have shot DrMike's Brenneke and found it to be a nice rifle to shoot. Definitely more felt recoil than my rifle, with the heavier bullets and more powder, but not objectionable or unmanageable.

Thanks for the welcome, really looking forward to playing with it as my first large cartridge, really appreciate the help I've received here as there seems to be a dearth of information on this cartridge
