I’ve gotten kind of busy lately and forgot I had loaded up a bunch of 115 gold dots with CFE BLK. I found the cartridge box with the load data notes in my range bag when I went out to confirm zero prior to deer season.

I need to do more testing with this round, but I’ve settled on 22.3 grains with on OAL of 2.150. My 18”, 5R barrel is getting around 2560 out of these little buggers. Primers look good and I’m not seeing swipes.

After deer season I’ll do some development and post some real numbers.

Those are great velocities.  Hope you fill the freezer with that load!

I would like to see your load data when you get time to do more development.  I have been looking for a good hunting load for the 115 gold dots, and CFE BLK is easy for me to purchase at my reloading store. 

I am especially interested in your velocity of 2560.  This is about the velocity I get with my 18” barrel 6.5 Grendel load with 120gr Gold Dots.

I've got some Hornady brass coming in the mail. I plan to do a couple OCW workups with both LC and Hornady brass in the coming weeks. I'll have to reconfirm everything when the weather warms up, but it will hopefully be a more complete data set. I finally have a chronograph setup that is relatively resistant to light pollution.

I've got some data, but it isn't organized very well. I don't have my load weight companion notes in front of me atm, just the raw velocity data. Through 29 recorded shots, over an undetermined spread in charge weight (10 different charges, 4 shots of each, 6 errors, 5 reserved) I'm looking at this:

Avg: 2583
StDev: 37.8
Min: 2502
Max: 2659
Spread: 157

Taken as a whole, the data isn't too impressive, but it shows promise. The weight that I singled out provided an acceptable group, and was on the higher end of the velocity range.
Real world, it punched cleanly through a doe at 115yd, right on target.

I'll update when I have more.

The velocity sounds impressive.  

I just finished locking in on a 6.5 Grendel hunting load with the 120 gr. Gold Dot.  About the best velocity I am seeing with this load is 2450 to 2500 out of an 18” ARP 3R barrel.

If you can drive the 115 Gold Dot to 2560 (and higher), I will give my Grendel to my son and only use my 277 wolverine for deer. 

I like the way the Gold Dots hold together and the 115 gr has a fairly high BC of .401 (compared to the 90 gr Gold Dot with a BC of .253).   Sounds like the perfect deer hunting load for the wolverine.

Be careful moving to Hornady brass. It is less capacity that LC, so step down your load and work back up. With the 100 MDWS I hit pressure signs almost a full grain earlier in the Hornady brass.

Good to know, thanks.

I was planning on fire forming them with a stepped own load.
