Different Bullets

[bighorn1]

I changed bullets in my 338_378 from Sierra game kings 250 grain to nosler accubonds in 250 grain both shoot the same at 100 yards but because of the different confidence do you think they would be a different drop at 500 yards.

BC for one at 0.565 and the other at 0.575, I doubt there would be much difference.....

That is published BC though, actual maybe there's more of a difference. 

You could check in a ballistic calculator to see what you can expect.   Try:   http://www.jbmballistics.com/cgi-bin/jbmtraj-5.1.cgi

I would shoot the Nosler Accubonds over Sierra's every day of the week. The 260gr Accubond from a .375 Ultra Magnum will flat roll/knock a mature Mule deer off it feet past 500 yards. I didn't get to witness the hit due to recoil but my spotter said it was one wicked hit.

Your rifle should push the 250's well. I was shooting the .375 260's @ 3050fps.

Okay I wanted to use the accubonds but a friend said he thought there might be a difference when shooting long range like 500 or over. I shot all my distances with the Sierras but not with the accubonds but will try to do that but hard to get in woods here so many gates are locked.

Here's a 260gr Accubond recovered from a mule deer I shot at 560 yards with a .375 Ultra Magnum. He was facing me head on, slight down hill shot. Hit him center of the chest, I recovered the bullet just under the hide on his belly.

The Accubond performed perfectly! Still had 2009 fps and 2329 foot pounds at impact at 560 yards.

Idk biggerhammer, York tested some gamekings for me and even he was impressed.

What does Yorke know??? He's been buried in a mountain of powder, primers, bullets and assorted shooting junk for way too long. Seriously, you have to question the mental stability of a guy that builds a .338-.408 Cheytac handgun.

He does seem to have Yosemite Sam syndrome...

I can understand guys that have "Issues" when it comes to firearms.🎯

While most people were eating lunch today, I was working out details and ordering a reamer for a .22 Nosler necked up to 6mm for a AR project.🙃

That could be interesting.

[Biggerhammer]

That could be interesting.

The rebated rim for a standard 5.56 bolt face, quality brass and 6.8 SPC case capacity sold me.

He has a point.....

I'll add two points here that I feel are important,  a 338-378 drives the he'll out of a bullet. I'd be all about a tougher bullet if you are planning on the under 500 shots. The game king is a great bullet in a 338win, but the e7i cas will over speed it and it will be  violent up close.

Second point is there is no substitute for actual field shooting. The ballistic calculator is a great tool, but it requires good data for good solution. Little nuances like barrel twist have effects on the BC of your bullet which create compounding accuracy effects,  or standard devation causing a vertical miss.

The only way to know that you are where you expect to be is to shoot farther than you expect to hunt and verify your ballistic solutions.

Relying on published data is a dissapointment waiting to happen.

How did I get drug into this??? Don't be jealous just because you didn't build the CT pistol first; you know you want one.


And I think I beat you to the 6mm project too while working with Gunsmith-X/McFiddlesticks like a year ago. You're just cheating and using the readily available 22 nosler case instead of forming it form an obscure European case. Fine, do it the easy way if you want. Maybe I'll just build a 6mm Dasher using the last of the ARP .473" bolts and extensions and run circles around your little 6mm.

Back on topic, I imagine that the 250 Accubond will drop more than the Sierra. Sierra is pretty darn close on their posted BCs, Nosler not so much.
