How will a boat tail help out if the velocity is still supersonic. If the the .338 bullet when it strikes is not supersonic at 400 years maybe it is not the right load to using. You likely need above 2000 with many bullets for expansion.midweight bullet w/ boat tail. ---SAWMAN
LOL go back and read what I wrote. I did not speak about reducing loads and you want above 2000 fps second.Read your above several times and I'm sorry,I really do not understand unless your writeup is a misprint.
A boat tail bullet is designed as such so that the bullet slips through the air more efficiently. (less drag)
Question - -> what percentage of .338" bullets are designed boat tail ?? WHY ??
Question - -> why would you REDUCE LOADS so that your .338" bullet IS NOT super at 400yds ??
Question - -> do benchrest shooters that normally compete at ranges greater than 100yds use boat tail bullets ?? WHY ?? Do ALL 1000yd shooters use boat tail bullets ?? Why ??
My opinion is - - -> load/use/shoot a lightweight to midweight bullet,driven as fast as accurately possible. It WILL be super at 400yds. Use a boat tail to help it's speed,help it's trajectory.
Shooters have been doing this for alot of years.
Sorry sir if I am missing your point. --- SAWMAN
The boat tail is better 'stream lined' for various reasons, but the big thing is the less drag on the bullet that is most important at and about the transonic range.Google factoid:
Is boat tail ammo more accurate?
The answer, and the reason, will surprise you. Flat-base bullets are inherently more accurate than boattail bullets because it is almost impossible to put boattails on perfectly. Even so, over long range, a boattail's ballistic benefits outweigh any manufacturing flaws.
At high velocity, the base drag is not as significant a percentage of the overall drag. But once a bullet drops below the speed of sound, into the transonic and subsonic velocity range, base drag becomes the dominant drag component.
You read it right and I know about boat tails I just heard a couple people arguing about oi but the ethicalness of shooting 400 yards with thatroud.i think it is ethical,and at 300 yards my non boattail factory round makes its mark every time, so I'm going with the 400 yard shots an ethical even without a boat tail. I load 180tsx and similar silvertips andwhitetail are easy to kill anyway. I appreciate your input.Read your above several times and I'm sorry,I really do not understand unless your writeup is a misprint.

Nowhere near subsonic. You have solved my argument. I'll take the panther to 400!How will a boat tail help out if the velocity is still supersonic. If the the .338 bullet when it strikes is not supersonic at 400 years maybe it is not the right load to using. You likely need above 2000 with many bullets for expansion.

I am confident I can adjust my scope to make my mark.Ethical depends on your confidence in hitting the vitals at that range! I am comfortable at 200-250 to take a shot with a damn good rest and enough time for the animal to give me the shot. Passed that, I usually don't take it. I shoot a 30-06 and a .308 at those ranges and know they can take deer out to 500+ yards ballistic wise no problem. It's the shooter (me) that is the weak link in the chain.
I took one shot on a doe this past season at between 275-300 yards and whiffed thankfully and I felt instant "you dummy" feeling after taking the shot!
So if you are a good shot, take it! If you suck like I do, maybe not.
Now on a hog hunt or some other hunt where "ethical" shot placement is not some magical "I have to recover" this animal thing, I have lobbed freaking artillery shells of 180 grain round nose 30-06 at what I am shooting at in hopes of getting lucky at damn near 500 yards!
Remember there are lot of fads in shooting relative to what is in use. I am not an expert ballistician. and suggest more reading for those looking for better information. What I have stated is generally true and I do not feel comfortable in adding too much to it.Yep,you need to go back and reread what I posted also re. benchrest shooters and 100yds.
Sooooo. . . the link and you believe that the boat tail design is only functional down around 1050fps,when the bullet goes from super to sub ??
If that us so,then why are so many bullets designed with a boat tail. And what percent of them,either factory or handloads EVER drop below 1050fps (approx. speed of sound) (5% maybe)
Does a bullets boat tail help to keep a bullet super at extended ranges ?? ---- SAWMAN
Major General Julian S. Hatcher was born in Virginia on June 26, 1888. He graduated from the United States Naval Academy with honors in 1909 and served in the Navy for 14 months, after which he transferred to the U. S. Army Coast Artillery Corps.
In 1913, he was detailed to the Ordnance Department, thus beginning his remarkable Army career in the field of ordnance, specifically dealing with firearms and soldier training.
His many comprehensive books and informative publications on firearms were widely used by both military and civilian agencies, particularly the Federal Bureau of Investigation.
He was the first Commanding General of the Ordnance Training Center at Aberdeen Proving Ground – from January 1, 1940 to June 1, 1942 – and was Chief of the Military Training Division, Office of the Chief of Ordnance, from June 2, 1942 to February 1, 1943. From February 2, 1943 to July 31, 1945, General Hatcher was Chief of Field Service, Ordnance Department, the most critical years of World War II.
General Hatcher died on 4 December 1963.
How much faster for bullets of the same ogive but flat base vs boat at 400 yards. No question that a round nose 30-30 slug will lose more velocity than a pointed design of bullet.https://www.amazon.com/Bryan-Litz/e/B00J216MMI?ref=dbs_a_mng_rwt_scns_share Bryan Litz has a series of books that was a gamechanger for me. It really caries over to the competitive world of shooting with hit probabilities and so on. He also shows formulas for a shooter to use in say a hunting situation that you could use in the field to keep things ethical. A Bullets BC shows at all distances through velocity. A bullet with a .250 G1 BC(Flat Base) vs a bullet of the same weight with a .500 G1 BC (Boattail) will be traveling faster at 400 yards due to its sleeker design.
At one time just about the all of the .338 bullets were flatbase when I had a .338 win mag back in the early 70's IIRC.I’m not aware of any .338 FB Bullets. I plugged in a American Eagle 55 FMJ BT vs a Berger 55 grain FB varmintBoth at 3240 fps and both .224 in diameter. The FMJ has a BC of .269 G1 and the Berger has a BC of .209 G1. The BT design travels 300 FPS faster at 400 yards although they both started at the same velocity
