Was thinking of building a 6.5-300 Dakota for whitetail deer hunting out to 600 yds max. I would be using an action off of a Remington 7 ulta mag. Probably will be shooting a 120-140 grain bullet. I was hoping to get by without fireforming but don't fully understand all the advantages of it besides more case capacity. I'm looking for any input anybody might have on doing a 6.5-300 Dakota and if there is any reloading data on it. I guess it would be similiar to Kirby's 6.5 AX. New to most of this but trying to learn.
that round would be very overbore but so what if its not gonna be shoot a whole lot no problem but unless you going with a barrel over 28" or so I don't realy see any advantage balisticaly over the 264Winmag.
The standard 7mm Dakota is a neat round or maybe a
7mm-300Dakota shooting a 160gr Accubond would make it a 600 yd deer gun easly probably enough for Elk that far and deer out past 1K
But personaly my longest shot on a big game animal which was a 120 od pound white tail doe was at a lazer ranged 618 yds abd that was shot with a 22" barreled 308 win and a 175gr SMK , she only went about 60yds or so after the hit.
Just to let you know that you don't need to be burning 75+ grains of powder paying $3-$5 per shot and get kicked hard to make the kill shots
Cool wildcat indeed. However, the 6.5-06 in a 26" tube would be just effective. I had one with a 24" tube and with toasty loads sent 140gr SST at 2950fps. No issue at 600yds for deer. In fact, I would have gone to 700yds if the op occured.
for load info, look up the 6.5 STW. Pretty close to the same case volume.
Here is another option you may want to look at if you bent on the 300Dakota case. With the advent of the new great high BC bullets that Kirby is using for the 270AM you could neck the 300 down to 270 and shoot one of the high BC bullets and you would have a 1000yd gun , I would think that you could push a 160gr bullet to 3200-3300 fps with that bore diameter.
Just another angle to look at but the 6.5 would make for a great LR gun but from my personal experiance the 140 class match type bullets don't like to be pushed much past 3000fps then the accuracy suffers .
But hey if you just have to have one and thats what you want then get after it , like it was mentioned before anything based on the Dakota case will be somehting differant.
