Home Forums Hunting & Shooting General Big Game Trophy bonded tip.

I've been using the 140's in a 7mm08 for a few weeks and have been very happy with the accuracy during load development. Largest groups were around an inch and smallest were .5" . Dug a couple out of the frozen dirt been and was happy to see that they held together quite well. H4350 is giving me around 2750 which is fine by me.

Interesting comments. I have seen excellent results on big deer and elk with the TBBC in .35 Whelen and 7mm RM. I’m sure the TBT produces very similar results. Funny no one has mentioned the nickel plated issue.

Is the nickel plating an issue ? Does it deposit fouling in the Bore or cause excessive erosion?

Not that I can tell. Only ran about 25 of them through my 270 so far but I can’t see a difference.

The Bore is DBC’ed though, if that matters.

So you are saying very minor differances in BC matter out to 600?
Which berger are you shooting in your -06?

WAM,

I've shot Trophy Bonded Tips in several rifles that haven't been Dyna Bore-Coated, and also own a Hawkeye bore-scope so can look inside the entire bore. Haven't seen any problems, either inside the barrel or on targets.

I'd like to see this bullet fired into dry print. Those water jug test are worthless.

SU35,

I've done that with both the original TBBC and the TBT, and the results are identical. Which isn't surprising, since the interior construction is exactly the same when both bullets are sectioned.

THAT, is good information. Thanks!

Yes thanks, I’m glad we are able to buy them. I hope they make other caliber bullets available, like 140-6.5’s. I don’t know if Jack made 6.5’s, I bought 7mm and .30’s from him.

I would like that for my 264!

Yep, Creedmoor and 26 Nosler too

What are the real world BC's on these bullets?

Not sure what the world is coming to. A couple days ago, smokepole agreed with me, today I'm agreeing with BWalker. Go figure.

Federal lists the .308" 165g TBT as having a B.C. of .45 and the 165g AccuBond at .475.

Looking at Federals ballistic charts, which only go to 500 yards, there is about 1" difference in drop and drift between their .30-06/165g/2800fps TBT and the AB loads. Using my ballistic calculator and extending the range to 600 yards, there is a 2" difference. Retained velocity and energy at 6oo come in at 1753fps and 1125fpe for the TBT, 1800fps and 1187fpe for the AB.

snooze...

And it would ake some crazy comparasion for a 30-06 to catch a RUM inside 600 yards.

I bought a box of 160 grain 7mm Trophy Bonded Tips but haven't shot them yet. I bought them for my 7mm Weatherby Magnum, which shoots the 140 grain and 160 grain Barnes TSXs very well. These new Bonded Tips should be more of the same, and with a better BC.

I still have two boxes of the original Trophy Bonded Bear Claws in 7mm 160 grain. I spoke with Carter on the phone several times back in the late 1980s. He said the optimum bullet in the 30-06 is the 165 grain. I used his 180 grainers in a 300 Weatherby to shoot an elk in 1991. Worked pretty good, too.

As I remember, Mule Deer said somewhere that the old Bear Claws shoot well if the bullet's shank fits your bore closely. If the bullets don't match up well with your bore, not so hot. The new Bonded Tips fix this with the Barnes-style grooves. Barnes TSX bullets have shot well in every rifle I tried so far. Several of my custom barreled rifles shoot cup-and-core bullets only so-so, but shoot the TSXs very well indeed. I'm going to try them in the Weatherby if the weather ever cooperates.

Or you could run some numbers, possibly be proven wrong, and have to submit that a bullet with BC .36 started at 3100 gets caught and passed by a bullet with BC .558
started at 2780 at 5000ft ASL. BC matters. More than cartridges, and long before six hundred yards. But what matters more, and what you seem to have missed, is that a light-recoiling cartridge with a very efficient bullet with quickly outdo a heavily recoiling cartridge shooting blunt bullets in terms of energy, drop, and drift, AND IT IS FAR EASIER TO SHOOT WELL.

I am looking forward to seeing how they hold up in my 300 Wby.. At 30-06/270 Speeds they seem pretty decent. The Weatherby will add some juice to them and see how well the bonding holds up.

Sitting on the sidelines here it looks like some of you are doing you best to disagree when you are in agreement. Billy Goat commented that often BCs are ambitious. Bwalker said that differences in BC don't make a significant difference inside 600 yards. It's important to note that he made that comment within the context of the differences between published and actual. Those small differences are of little consequence inside 600. Huntnshoot told a story about his 30-06 passing a Remington 300 RUM at 400 yards for energy but didn't mention the specific loads of either. Bwalker said it would take a crazy comparison for that to happen. Then Huntnshoot presented an unlikely comparison best I could tell. What 300 RUM load is launching a .36 bullet at 3100 FPS?

Playing the roll of peacekeeper here using the individual points made.

Do either of you disagree that small differences in BC make little difference inside 600 yards?

Do either of you disagree that the difference between a BC of .36 and .56 can make a pretty big difference?

Do either of you disagree that for most people it's easier to shoot light recoiling guns more accurately than a heavy recoiling gun?

This is a pretty handy online ballistics calculator.
