The accuracy of a flat base is really no surprise, as most of the true match bullets were, and still are flat base bullets. I truly believe, that it is because if the bearing surface, or better put, more of it. I would think that the construction would be simpler, making it less apt to be flawed. Some rifles , long throated or not, simply prefer flat base bullets, period.
I was told by a teck from Sierra, years ago, that the advantages of a boat tail, don't really take effect til AFTER about 500 yards. Additionally, he said, that a flat base bullet does not " yaw" like some boat tails do, rather, they stabilize very quickly. It goes to show ya, that guns ARE like women, they want what they want, and nothing else will do!

I had the same experience with a custom 25-06. It would shoot deer hunting accurate with boat tailed bullets out to 300 yards but never could get it to shoot much under 1" at 100 yards. Then I tried some 117 Sierra Pro Hunter flat based bullets . First three shots were in the same hole at 100 yards. On a calm day it will shoot 1" average at 300 yards using the max of 12 power and the heavy cross hairs that are in the Ziess #8 retical. I once shot a deer through the eye ball purposely at 287 yards with this rifle. It was the only shot I had and I knew I could make the shot. He had come 4 evenings in a row and stood behind a big pine tree just before dark and would not come into the field. He most likely had seen me move or had been educated by someone else hunting from that stand. I had to leave and go home from the hunt the next day. He was a nice 8 pointer.

Re: H4350 Flat Base Bullets and Now, Success

I have never used the Sierra Pro Hunter bullets ...................because of the great accuracy they give me in my .243 I will be using them for Antelope, Deer, Black Bear, and Cow Elk this fall and a Mt Lion if I happen to see one.............

How do they work for you .............do they hold together?

Re: H4350 Flat Base Bullets and Now, Success

The Sierra is a standard cup and core old school bullet. For many years they have and still do kill a lot of game. It all depends on impact velocity. The higher the velocity the more likely they will shed their jacket from the core. This is not a really bad thing as some bullet companies that what you to buy their new bonded etc. bullets what you to think. On the normal inside 200 yards bullet placed in the center of the front shoulder of a WT deer from either my 25-06 or 243 Win you will find the jacket of the bullet fully expanded with no lead core attached just under the hide on the off side after going thorough both shoulders and destroying the vitals. Most of the time the deer drops in it's tracks. Beyond 200 yards the bullet has slowed down enough that it usually will exit the deer. I have used the 100 gr Pro Hunter flat based bullet to kill a bunch of white tail deer from a 243 Winchester. For that purpose and the results I got you could not ask for anything better. The 117 gr Pro Hunter is THE BULLET for white tail deer from my 25-06. I and my hunting buddy have used about every make bullet in most calibers from 22 through 45-70 to kill white tail deer. We control hunted a big farm in east NC for 20 years and took 100 deer each year. We learned a few things about deer bullets in the experience. Bullet placement is the key to quick kills. If you put a Sierra big game bullet where it is supposed to go it will get the job done. If I were to use your 243AI for elk and possibly black bear where I wanted to break a shoulder I would use the Speer Grand Slam. I tried some 120 gr. in my 25-06 a number of years ago on WT deer and they did OK but on those light bodies I like the more expansiveness of the Sierra 117. Those Speer Grand Slams do hold together and keep on trucking though. I once shot a good size buck at only 50 yards that was facing me. Bullet impact from the 25-06 had to still be over 2900 fps. Bullet centered the chest taking out the lungs and the buck fell back on his butt and did a back flip and kicked about three times and was dead. When cutting up the buck I found the bullet under the hide of the right ham after it went through the center of the ball socket. It was a text book mushroom and weight was 87 grs. Funny how I can remember stuff like that from years ago and can't even remember my phone number half the time. By the way those Grand Slams shoot very accurate in my 25-06. Good luck and good shooting.

Re: H4350 Flat Base Bullets and Now, Success

I really appreciate your input. Very very few guys out there with the kind of experiance you have and the ability to try different kinds of bullets. I will try some Speer Grand Slams. I will admit that after seeing several really big Boar Black Bears this spring in the area I hunt I was a little intimidated using a .243 My son shot an average Black bear last year using the .243 and it killed it dead with the first shot range we measured at 211......................But the ones I saw this spring ..............wow big difference.

Thanks

Greg
