Nosler Accubond Long Range problem

[MontanaRifleman]

I would agre with the partition design, but I would LEAVE the tip and get rid of the hollow point underneath it. This is why they are so explosive! I've made partitions like this with my bullets and they work great. If you get rid of the tip, you basically have a Berger with a partition. Not a bad idea but no expansion at 1300' either.......Rich

Yup, a Berger with a partition. About as close to an all around bullet as you can get.

I don't see expansion down to 1300 fps in the smaller bullets as being all that beneficial. With a 150 gr bullet, that amounts to about 560 ftlbs of KE

The cavity behind the tip is what helps them to expand down to 1300 fps. With the partition design, the bullet would retain over 60% of its mass.

See, I toldja it looks like a fish finder

What about with larger/heavier bullets?

Take away the tips, and I project you'll also lose reliable low velocity expansion.

Partitions will increase production costs, and could make it difficult to produce target quality, accurate bullets. The partition is another piece of metal to get perfectly balanced for high rpm travel down range.

In order to have a cavity behind a tip, you have to have a tip! Without the tip, you have expansion at closer to 2000'. I would agree that 1300' doesn't buy you much with the small calibers. I was thinking more in general with the .308 on up........Rich

Yeah I know Rich Just considering the options

Well, it seems that Bergers expand failry reliable to 1800 or less. I bet one of these bullet makers could come up with a tipless partition that expanded down to 1600 if they put their minds to it.

I always had good accuracy with partitions, even with deformed tips. Heard the same from others as well. As for cost, if you want the perfect bullet, you're probably gonna have to pay for it and if you remove the tip, that should lower cost a bit.

Yeah, you probalby won't get down to 1300 fps for expansion, but if they worked on it, like maybe scoring the tip or something, I bet they could get it down to 1600. The problem is trying to get these guys to think outside their little box!

We could start yet another debate as to whether or not a Berger will expand at 1800' (or less) but neither one of us would change our minds and I kind of like you, so! I have PERSONALLY NEVER been able to expand one at 1800' in anything resembling something that breathes! If you hit bone, yes. I'll say it again, I like Bergers, and sometimes use them, but this is my experience. I do agree that if the companies wanted too, they could make a hollow point that will expand at 1600'. I can and I'm a dummy with little resources......Rich

I'm not adverse to loading and using two different bullets. One for long range and one for closer ranges. I've been doing this for many years now and I've never felt handicapped in any way. But these ABLR bullets need to be accurate in order to provide the option of using them at long range, where their value and ability to expand at long range low-impact velocity is being demonstrated.

I've never tested the Nosler Partitions at long range for accuracy, so I am only guessing there. I think it would be difficult to get them to shoot like Berger target bullets at 1000 yds, but again, I've never attempted it. Have only used them as a closer range hunting bullet, primarily on moose. I've had them shed 50% of their weight on moose, in the .338 Win Mag - 250 grainers. But the butt end has always remained intact.

hahaha, I KINDA like you too Rich so we'll leave it there... except to say, I recall Broz bagging a speed goat at over 1200 yds with his 300 WM and 215's. but that is only a sample size of one, so who knows

I have NO DOUBT about Brozs success with Bergers and have never questioned that. Did anyone recover the bullet to see if it expanded? I've seen military rounds leave some very nasty large holes! This is especially true when a bullet does not expand and tumbles which is what nearly every unexpanded bullet does after travelig a liitle ways through tissue. I guess if you get 19 for 19, who cares if it expanded or not Just sayin'.....Rich

I reloaded some loads with the 168gr (78gr - 80gr with .5 gr increments) and 150gr (81.5gr - 83.5gr with .5 gr increments) today for my twin Remington 700 Sendero SF 7mm STWs. Powder is H1000 and Fed215 primers.

I'm going to the range tomorrow morning and I will report back with results.

Back in my bullet retipping days, which may have to be resurrected, I found that the angle of the point base is a major factor in expansion characteristics.

With the base of the ~12 grain brass tip machined square results were pretty much identical to factory Ballistic Tip performance.

With a slight slanted base things became explosive right quick.

There was no void behind the tip and the tip was tapered in steps and press fit into the bullet.

Roy, I hate to say it but we must be related I have some tips that I machined with a 15 degree angle at the base to wedge the jacket just as you described!!........Rich
