Ballistic Tip ?

[BeeTee]

So is pushing a 150 BTip out of a 7mmRem pushing the limit on shots from 20-500 yards?

In 1992, I bagged a large cow elk at 450 yards using a 7RM & Nosler 140BT. It was an instakill with a behind the shoulder hit. The jacket stopped just under the hide on the far side. Not sure what might be better than an instakill.

The 7mm 140 gr BT is a real shooter in my 280AI too.

If anyone has any doubts about the toughness and performance of the 165 Partition, I will tell you a story about a large (275 pound dressed) 4-point mule deer that I shoot in Colorado some years ago with my .300 H&H and 165 gr Partitions at 3150 fps. I held on the deer's back line with the scope hairs and bullet dropped about 6 inches into a high lung shot. So, it had to be at about 300 yards range, considering 6 inches drop when sighted at 200 yards.

At the shot, the deer rolled on his back and one foot shot up into the scope field when I came down from recoil. This deer was dead, DRT. However there was a 2-point standing in the brush about 25 yards behind the 4-point that I shot. I had not seen the two point before shooting and he was standing head down and walking on his intestines after the 4-point fell. The guide had an extra tag and was good enough to shoot and tag the 2-point for me, thank goodness.

I felt really bad about the screw up on my part and offered to turn myself in to the local warden but the guide said "no issue". He was glad to have the extra meat. The reason that I am mentioning this is that if anyone here has doubts about premium 165 gr .308 bullets don't have. Because this Partition at 300 yards, went through two deer completely and killed both deer, despite my screw up!

Yes, the Partition is a classic that continues to deliver!

That was a big mulie. Congrats. And really good of the guide too.

Guy, Fortunately, that was the only time that I ever unintentionally killed a deer standing behind another one, knock on wood!

130 grains nosler bt 270w
V0= 980m/s
This roedeer (capreolus capreolus) was shot at 130m

This Dama dama, distance 150m

I feal they are a little bit soft for bigger game.

Phew, yeah the 130's might be a touch too fast but I bet if you kicked up to 150's the extreme damage would slow down a bunch.

Sendero - quite a difference from the rather clean & neat bullet wounds in my photos on page 1 of this. I haven't seen destruction like that on a deer-sized animal in a long time. Last one I recall was from the original Ballistic Tips, about 20 years ago, and a .300 Win magnum and a 165 gr Ballistic Tip at about 3200 fps. It literally blew a leg off a mule deer at fairly close range.

Looks like your top photo shows a bullet/spine impact. I can see how that could cause bullet blow up.

Not even sure what the bottom photo shows... Except something looks like it got real dead.

At any rate, thanks for posting.

Regards, Guy

This is 140grains nosler AccuBond 270w
V0= 985m/s (3232ft/s)
This is not that explosive as 130bt even that the bullet runs faster.

The AB will definitely stand up to that high velocity better than the BTs. I keep the 130gr BT velocity right at or just under 3000fps in the .270s I load for and have found them to be more in line with the expansion/trauma levels I'm hoping to attain against deer and black bear. We dont shoot game beyond 250yds very often so there's no desire/requirement to keep trajectories flat as possible.

I have no idea how you're getting that velocity out of a 270Win and the 140gr AB but I'd advise against it. Buy a 270WSM or Weatherby if you're looking for more speed. Just my .02¢

I have an old lot of Raufoss NCRA15.
Norma brass.
59.5 grains NCRA15
Remington sendero 27" lilja barrel.
This load gave the best group, it tightend upp.


Best 3 shot group with 61.5 grains (3297f/s) but that load had dangerous high pressure sign.

Excellent shooting! Way to go. That is a screamer for sure.
