I was wondering if anyone has had good luck completing load developement with the ballistic tip and then substituting the accubond for hunting?

I replace valve cover gaskets every 50K, if they don't need them sooner...

I was just thinking I'd save $7 bucks a box but in reality I guess it really only amounts to $14-21 for load developement. Maybe even less if it goes well.

I do just that in two rifles. A Rem700 in 7mmSTW and a .270Win. with their respective 140gr. bullets. If there's any difference in pressure or point of impact I have yet to see it.

In general my exprience is that any load developed with a BT will work just as well with an AccuBond of the same weight--but there have been occasional exceptions.
Most AccuBonds appear to be bonded versions of the same-size Ballistic Tip, or at least that's what I've seen when sectioning them. But there are sometimes slight differences, which may (or may not) account for the occasional exceptions.
Also, AccuBonds tend to have slightly softer jackets, due to the bonding process. This may also have an effect when working up loads for the two bullets.

I was wondering if anyone has had good luck completing load developement with the ballistic tip and then substituting the accubond for hunting? OK I am not a Gun Writer... But in my middle son's New Win Mod 70 (30-06), 150g Accubonds and Ballistic Tip bullets shot to just about the same POI (as far as I can tell). We shot some (side by side) before his most recent hunt just to be sure... We did not run them through the Coronagraph� we should do that sometime this quarter

They shoot the same in my 270. Have tried 130gr Ballistic tips, Accubonds and Partitions with same loads. The only difference I saw was that Partitions were about 30 fps slower.

In my .30-06 the 165 BTs and 165 ABs shoot to the same POI with 57 gr. IMR 4350 or 56.5 gr. H380. Works for me.

Hi JB.
I thought the AB had a thicker jacket than the BT.
Is it true only the lower portion of the bullet and core are bonded?
Thanks

I have only compared using the 7mm 140AB and the 140 BT, same load did not work. In what chamberings were they interchangable for you? In general my exprience is that any load developed with a BT will work just as well with an AccuBond of the same weight--but there have been occasional exceptions.
Most AccuBonds appear to be bonded versions of the same-size Ballistic Tip, or at least that's what I've seen when sectioning them. But there are sometimes slight differences, which may (or may not) account for the occasional exceptions.

Bigbuck,
I wouldn't approach a load workup that way, but where the NBT/NAB "synergy" really shines is in practicing with the NBT but hunting with the NAB. If you shoot a lot, it's a real bonus, and to that end I use NBT's in my 7-08 and 30-06 but switch to the Accubond for hunting. POI is verified as the same out to 500 yards (for practical purposes), and the load is identical.
I sure wish there was a 7mm 160-gn NBT...

Can't imagine it would be a real problem.....the Nosler Manual lists all their bullets of the same weight but different styles together(BT,AB,and Partition).
If there were a universe of difference in load data for the three I'm certain they would mention it.
I'd work up with the BT;develop the load,then back off and come up again with the AB.I suspect you will wind up pretty much the same place.
Use the chronograph as you go;watch for pressure signs.You should be fine.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

EddyBo,
Damned if I can remember all of them, but it's been quite a few. The .270 Winchester with 140's is one, for sure.

In my .300 Win Mag, the BT and AB 180's shoot to same POI, although the BT's slightly edge the AB's in accuracy, as I recall. Would like to hear other comparisons of the two.

In my .338-06, 200 grain BTs and 200 grain ABs essentially shoot to the same POI at 100 yds. With 130s in my .270s, the BTs shoot about 1/2"-3/4" higher at 100 yds in a Custom Mauser with a Shilen barrel. They shoot to essentially the same POI in both of my pre-64 Models 70s, one a Fwt and the other a Std weight.

Mudhen,
Are they making the 200-gn NBT in .33 caliber again? I loved that bullet in my .338 and was bummed when they discontinued it.

Hard to beat the 225 Jeff, I reckon they figured that out.
