Great to see your results. I was also a little surprised. I had a .338 Win Mag I’d just about given up on. Had it out to the range, was getting usual crappy results. Two acquaintances wanted to shoot the rifle, and they both shot sub minute groups…get this, they had no experience using the bags!!! The rear bag just happened to be high enough to lock on with a bit of downward pressure, and otherwise they were both gripping the forend with left hand, a conventional rifle hold (but forearm supported on the front rest)…..well it turned out that was the key! Using that technique I got really good results with that rifle and several other hard kickers.
Glad you found a good load for the 340. I've heard good things about those Hammer bullets. I don't know what's up with the 7828ssc - I haven't seen it available in a good while.
It's fascinating to watch you carefully tune these all copper bullets. I've never had the opportunity to try them, but here recently, watching your success is making me curious if I might be able to find similar results with some careful tinkering. Course mine has a larger project attached if I actually do find they shoot, but hey, one step at a time. Good video as always!
Excellent results, thank you for posting. If you are interested, the new Garmin chronograph is extremely easy to use. The set up is very fast with no fussing at all.
@@AlaskanBallisticshow do you even compare? The 270 is better ballistically and can kill most of the same game. But I still prefer the power of the 30-06. The 30-06 has taken everything from rabbit to elephant.😂
@@jam5287 barnes has a 130gr .308 diameter bullet. I can only get it to go about 3175 in 270, but I can get it to go 3325 in .30-06. 150 fps makes up for the higher b.c. of the .270 out to reasonable hunting distances. Down here at sea level, you can't stabilize the heavier bullets in 270. But 165 in a .30-06 is ideal all over.
@@AlaskanBallistics that’s also because 130-150 used to be considered heavy for the 270. Where 130 is insanely light for the 30-06. Go down to 110 or even 95 grain ttsx. The 270 can truck along anywhere from 3,300-3,700 fps with those bullet weights.
3 round cloverleafs are ALWAYS a good thing… BUT… I have been burned way too many times making load development decisions for factory hunting rifles based on a random 3rd group. These days I just run a 9rd ladder in 0.5gr increments to find pressure, pick a safe charge, then load up a 6rd sample. Shoot 3, cool, shoot 3 to build a 6rd group. There is roughly an order of magnitude more meaning in a 5-6rd group compared to a 3rd group and mean radius is a much better performance metric than extreme spread. Cheers!
Great shooting. I had commented that I shoot the 213 grain hammers through my 340. After a fair bit of testing wouldn’t you know I also ended up loading my rounds with 7828 ssc. They’re moving out at 3230 fps. I doubt I’d go any faster as that’s probably at least at max but I saw great consistency around that level.
I'm soo happy for you that the 340 definitely has accuracy. My 6.5rpm is the only mark5 I have that that loves the cheaper hornady ammo. Hammers are awesome, and superior to the barnes bullets terminally in my opinion.
I’m in Canada. Imr 7828 hasn’t been available at least locally for quite a while. Then again r22 hasn’t been available either. I’ve got a bit of both put away, but hoping to see both back in stock before i run out of them.
Been shooting a 264 win mag all my life. But just got my supressor out of jail and my 264 isnt comp threaded its old school was my fathers so im never gonna hurt it in anyway. But that being said now i have to build a new deer rifle to slap my sandman s onto and im having a tough time figuring out which caliper i should be getting. Love love love the 264 win mag but i was thinking along the lines of the 6mm ARc or 300wby but seeing these numbers really make me want to look more into this 6.5-300wtby. Im a farmer and most of our shots start at from anywhere to a random close shot but most of the time they are 4-900 yards out so wouldnt mind having a gun thats not dropping like a brick after 500 yards, i saw your writers killed the 264 i totally agree thats a hidden gem hot shooting little banshee of a gun.
I know powder is hard to come by, but by chance do you have H-1000 or Rl25? These two both work great in my 338 RUM. I used to shoot Rl22 when I first got the gun many years ago with lighter bullets.
@@ReloadingWeatherby The big question will be if you have enough case capacity to get the velocity you want with H1000. Very temp stable. I run 225 gr accubonds at 3215 with 97 grains and my bullet stuck out just off the lands. Worth a shot.
Still waiting for you to reload 240 WBY! You can still pick up a Weatherby Vanguard synthetic in 240 Weatherby of their website. They discontinued the 240 Weatherby in the Vanguard line so when they're gone they're gone.
I just started watching your videos tonight. I saw about the broken stock. I can't find a video where you address what happened, just that you went shooting again and the stock held up. Did they give you a new stock or replace the entire rifle or what?
The 340 is just super leathal with for any game animal on earth with the right bullets . The 340 with a heavy jacketed 300 grain round nose would zip through an elephants skull or penitrate a cape Buffalo length wise. 250 grain Nosler partitions will kill the toughest African plains game at longish hunting ranges.
Looking at my note book for my 340 WBY with a 225 gr Hornady spire point I was shooting 86 gr of RL 22 with a FED 215 primer and getting about 3/4 in groups . Have you chronographed the 78 gr load ? I think it going to be well under 3000 fps . The length ( COL )of this load was 3.650 in . Thanks for the videos !…….
My gun is much faster than the books. I would be in trouble loading 86 gr of RL-22 with a 225 gr. Go check out the Barnes data for 225 gr. My gun is over 300 FPS faster than what the book says.
@@ReloadingWeatherby BTW the IMR Handloader’s guide for a 340 WBY states 89 grs of ( 7828 ) Max for a 225 gr bullet and Fed 215 primer. This is a compressed load as stated in the manual !…..
@@ReloadingWeatherby Is there any way I can send you a picture of the IMR Handloader’s guide page of WBY cartridges with 7828 powder ? It covers all WBY cartridges at the time of publication with the then new 7828 powder . This was published around the late 80s and early 90s , I have found it to be good data for several WBY cartridges 270 , 300 and 340 WBY !
Does your new Weatherby in the .340 still come with the long "lead" as the older Weatherby's have ? Also, what overall length did you seat the 220 gr Hammer bullet to ?
I use .300 wm for elk and I know the 340 is up there closer to 375 but what would you say is max effective range on elk/moose. I’ve never shot or owned a .340 but I like exploring calibers I’m not that familiar with.
I'm not a fan of long distance hunting... but with the 340 Weatherby your max distance is 650 yards with a mono bullet. The energy isn't the issue... it's the velocity of it expanding.
What more awesome is that view at your damn range lol. Where the hell is this? Probably the reason you’re stabilizing those 165’s in the 270. Try that at sea level lol
The Weatherby chambers have always had a very long lead . I have measured several Weatherbys over the years and they have been 3/4". this makes it impossible to seat bullets to within 20 thousandths of an inch, In some cases some shooters like to seat bullets touching the lands. This will make cratridges long and will not fit in the magazine but the accuracy gained from doing this is great. When I heard the Hammer bullets were being used in Weatherby's ammo I got interested.
Yes... Weatherby cartridges in Weatherby rifles have a lot of free bore. With that being said... my most accurate rifle is a Weatherby in 257 Weatherby
@@ReloadingWeatherby especially in 257. There are a few larger caliber but those are too much for me being smaller stature. Nice channel great information. Keep up the good work!

Hammer bullets are absolutely NOT known for their accuracy. You are wrong. Hammer bullets are known for producing higher velocities due to how the grooves are cut into the bullets. This process produces reduced pressure and potentially greater speed.
