Home Forums Hunting & Shooting Hunting Rifles 270 Wby loads

Mr. JB has a fair amount of data on hand. Some in particular for Ramshot Magnum. Maybe he'll stop by. My personal load when I was using my Euromark on steel plated deer ended up as 72gr RL-22 with a 150 gr Interlock at just over 3200 in a 24" barrel. That's way over what Hornady lists now and maybe more than I should have loaded. But it was genuine inch or less at 100. Even shot one 3 shot at 200 that measured 3/4. One.

Don't know.

Using RL-22 and Nosler 150 PT's. Just shy of 3100 fps across the screens, not a top end load and there seems to be more left if I would wish to increase it but I am looking at making those cases last more than 3-4 firings.

That's an interesting combo.

I just ordered blems from SPS, 130 gr. and 140 gr. NAB's, 150 gr. NPT's, around $17 for 50 bullets.

I'm concerned that combo could be a bit expansive on WT's and such.

I've gotten 130 gr. Accubonds to try, along with 140 gr. Accubonds and 150 gr. Partitions. Hopefully NAB's will hold together a bit better than NBT's at those speeds.

I think I am going to try cutting edge for my 270

I killed an 80# hog last year with a 135 gr. Cutting Edge Raptor out of a .308. Impressive kill, lung shot. Hogs often run, shot thru the lungs. I chest shot this one just to see what would happen. DRT.

The petals frag, sorta like a mono trying to be a Partition.

Some complain when a TTSX loses a petal. This bullet loses them all by design. You can see how the bullet missed the spine, the petals got it.

It should work in the .270 Wby, or in about any round.

May frag mo better at higher speed. Monos are said to not have a velocity ceiling, although that's another story...

That is impressive, how hard was the load workup?

130BTs were my std.load in my 270wby and it was my go-to wild boar rifle.
it never disappointed even at rather close ranges where impact vel was easily 3100+
but that was before I was told I needed premiums.

Easy, just fell together.

Gun is a Kimber Classic with a 5C Broughton SS barrel. It shoots about everything well.

I was, however, surprised at the accuracy of the CE bullet. It killed as well as it shot.

They're not cheap, but how many do you actually shoot at game.

DF

A 270 Wby should push 130 NBT's a lot faster than that, more like 3,350 or so. I'd be concerned about NBT's coming unglued at that speed. Full out you may need premiums.

I'm new to the 270 Wby, working with this one for a friend. So, there's a lot to learn, a lot I don't know.

You might try RL25, JB worked up some loads with it several years ago with impressive results, if anyone wants a copy of his table PM an email address to send it to

I've been working a bit with a new LH Mark V Ultralight in .270 Wby (26" barrel). Here's a few results:

140 gr Accubond/ RL 22 / 70 grains / 3260fps avg.

150 gr Ballistic Tip / RL 22 / 69-70 grains / 3220fps avg.

150 gr Partition / RL 22 / 69.5 grains / 3240fps avg.

Weatherby cases, CCI 250 primers

All loads shoot 1-1/4" consistently; some groups go 1".

I use a few full scoops of 7828 in mine. I've killed white tails and mule deer with the rifle, but none with my hand loads. Oh- I also loaded 130-grain BT's with the 7828, looking forward to trying it out on whitetails this year! Accuracy was good when I was developing loads- my rifle is a Mark V, it liked the fastest loads best for accuracy.

Modern Reloading by Lee says 3500 fps with 130g bullet in .270 Wtby. with 7828. Haven't tried that in mine yet.

I have had great results with 7828/SSC, RE19, and RE25 using 130 Ballistic Tips. Makes for a super Pronghorn round. Probably a bit fast for Whitetails or larger unless you are shooting them out there a bit. If I wanted to do what you are trying to do I would develop 2 loads. One would be speedy 130 Ballistic tip load for Antelope. The second one would be a more sedate velocity load using a 140 or 150 Accubond or Partition. I think one load for everything would have to be a compromise somewhere and why shoot a WBY if you need to compromise.

130 NBT at 3,500 fps would probably be a bit too much of a good thing on WT's, etc. I bet a Ballistic Tip at that speed would be a bomb, I wouldn't push one that hard.

DF

I should have included that I have a supply of 130g NAB's for trying the Lee 3500 fps load.

Shot a Muley with a 130gr @3500 out of a 270Roy, except the bullet was a Barnes TSX.
I don't know what a 130gr Ballistic Tip would do at that velocity, maybe instant hamburger?
