375 caliber long range bullet

jsl3170375 caliber long range bullet
Can someone else check their copy; Ammo and Ballistics II by Bob Forker, p. 209 lists an A Sq 300 gr SBT load for the H&H wiht the following:
sighted in @ 200 yards.
MV 2550 fps
G1 BC= .641!
at 600 yards this thing is still showing 2163 ft lbs energy.
admittedly, such distances are beyond my abilities at this stage but, is such a bullet a viable long range hunting round or is it better suited for punching paper and/or non-living targets at that range? and dos SBT stand for Sierra Boattail?
By comparison, the 300 gr Federal loaded NP further down the page shows a BC of .409 and 2040 ft lbs of energy at the 400 yard mark.
just wondering.

Check out the 260-grain Nosler Accubond and don't believe everything you read.

Yes stick with the mid range bullets 260-270. Although you can approach 3000fps with the 235's, their BC makes them slow and drop more than the heavier bullets. Likewise the 300's are a little slower out the barrel.The 260-270 range is probably the best for anything but buff and ele.

eezridrNosler was supposed to come out with a 300 accubond. I have not seen any on the shelf.
The 300 grain Sierra does have a pretty good BC. Not sure what it is, but I recall it's being pretty high for a .375 bullet. Craig Boddington has written some nice things about it too.
As others have said, the 260 Accubond may be the best choice. Good BC, reasonably stout, and more initial velocity than a 300 grain bullet. IIRC the BC on the 300 grain Accubond is barely more than the 260.

Interesting. Several shops over here in SA are adertising 300-grain Accubonds at present. Perhaps a shipment got diverted to SA?!
A Barnes or other mono-metal bullet may be the best choice, providing a longer bullet at a lower grain weight. A 250gr Barnes TTSX has a BC of .424 in 375.
Wow, a Sierra Gameking BT has a BC of .480 at velocities between 2,200-2,600 fps, and a SD of .305. That's great performance, provided it's tough enough to do the job when it gets there.

steph123I have had great success with the 260gr Nosler Accubond. Longest shot so far was an elk cow at about 350 yards. I shoot them at a muzzle velocity of 2700 fps, BTW. My experience with the Sierra 0.375 bullets makes me believe they are only good for shooting paper, although they are accurate in my rifle.

BarstoolerI have two boxes of 300gr Nosler Accubonds. Bought them at Sportsman Wharehouse two weeks ago. Have not had an opportunity to load/shoot them yet.

Only if it opens up reliably at the range you're shooting. If you're looking to make 400 yard to 600 yards shots, make sure your bullet will expand at those ranges/velocities.

Just looked up the 2 Accubond 375 bullets. The 260gr has a BC of .473 and a SD of .264, and the new 300gr has a BC of .485 and a SD of .305. Both look great for long-distance use of the 375.

chuck375Sounds good, wonder what speed I can get out of my 375 Weatherby with that 260g Accubond.

Don't know much about the Bullet..., but it's listed as a long range " Match / Tactical / Hunting Bullet "
Bullet: .375
Grain: 320
BC: .830

Lee WoiteshekI'm looking at using a 270 grain TSX at 2700 and change for 300-500 yard shots. Should I be using something different? My concern with the Accubond is will it hold together if I have to shoot an elk off the barrel at say 50 yards?
07 May 2011, 01:53
chuck375I can't say for the Accubaonds, but a Nosler Partition will hold together and penetrate at 15 yards and still expand at 600 yards.

Chuck

steph123Lee, I have shot clear through a mature bison with the 260gr Accubond multiple times with no issues whatsoever, see avatar pic. I have also shot elk with them from 70 to about 350 yards, again no issue. So as far as I am concerned it is all the bullet I need for my 375. I have had the Sierra Gamekings literally explode on elk at about 100 yards. I shoot the 260gr Accubond at 2700 fps. I have used the 260gr Accubond on a water buffalo also, again it worked well.

Lee WoiteshekThanks, where I hunt elk, the outfitter asks that you show up with the rifle zeroed at 300 yards. I'm in love with the Barnes TSX series, but if I'm below the velocity threshold for it to work at 400 or so yards I need to go in another direction. I will look at the 260 grain Accubond. The new 250 grain TTSX intrigues me, but I might be facing the same issue.
Lee, Accubond will be perfect.

Jeff,
In 1982 I shot 300 grain Sierras and noslers from my pre 64 mod 70 from point blank out to 500 yards in 100 yd incriments into 5 gallon buckets of water and they had jacket core separations at every range.
To their credit they expanded to 500 yards.
But the nosler partitions, both old and new style expanded at to 500 yards also. And had 1/3 more penetration.
The sierra has a much thicker jacket than smaller calibers but that boat tail is just a core shucking device if there ever was one.
My freind Bill Steigers bonded some Sierras for Sierra and they were a beautiful bullet. Sierra almost got into the bonding business that year. Too bad they did not.
The 300 grain BTSP is heavy enough and slow enough you can hunt with it, but there are certainly better game bullets out there.
Out to 500 yards a faster, slightly less BC bullet will have less drop and wind drift. It is only past 500 yards the higher BC bullets pay off. The 250 grain Bitterroot at 2950 fps only required 9.5 minute come up for 500 yd zero, while the Sierra was about 11 minutes as I recall.
These were real world results with a 10X target scope, not from a reloading table.
If I were target shooting at 1000 I would certainly shoot the heavier bullet.
After trying them all, with bullets available today I would look at North Fork, Swift, Kodiak, Nosler partition, Barnes TSX, Accubond, and Woodleigh protected point in that order.

akalininDoesn't Sierra make a 350gr .375 Match King bullet for the 375 Cheytac? I'm pretty sure you can still get them at Graf & Sons.

Andy, excellent post. I have friends that use Sierra Game Kings for elk. They're fine at long ranges and for close up broadside shots, but they wlll come apart on close up shoulder shots or fail to penetrate enough on close up quartering shots sometimes as well. I have routinely used Nosler Partitions instead which I prefer to Swift A-Frames on thin skinned animals since they expand faster but still penetrate. I have to say Sierra bullets are almost invariably the most accurate from my rifles. A bonded Game King would be an awful nice bullet, too bad the didn't go that route.

Chuck
