A good bud just had an old Ruger tanger 7RM re-barreled with a 26" #3 Shilen in 270 Wby. He mainly hunts WT's, pronghorns, occasionally bigger stuff.

I load his ammo. What's a good place to start with that round. I have most powders, like Magnum, 7828, MagPro, 4831, MRP, etc., have a few 140 gr. NBT's on hand. He'll pick up what we need.

DF

I use 7828 in mine. 72.0 grains and Barns TTSX 130 grain bullets. But be careful that's a maximum load in my gun anyway.

7828 and 140 Accubonds work great for me. In a Mark V Classicmark. Used on whitetail,mule deer,pigs,axis and aoudad

Looking to try the 150gr Long range accubond soon.

He likes Partitions. We'll have to see if it likes them

NAB's may be a back up. He's not a Barnes fan.

140's may be better in that round than 130's, as they'd be moving pretty fast, maybe too fast.

DF

I use RL-19 and 130 gr NBT's in my .270 Wby.

When Barns had the X bullet, I wasn't a fan of Barnes either. But when they came out with the TSX, I tried them and I liked them.

I like'em too.

But ain't my gun, or my choice.

I may try some TTSX's for grins.

DF

What's terminal performance like, those NBT's at warp speed on critters, not counting jackwabbits...

DF

Eventually I'd like to get a Ruger #1 in .270 Roy. Based on results so far I'd probably try Reloader 26 in it.

My Ruger #1 in .270 Weatherby likes 140g Hornady BTSP's over a max charge of 7828.

140 accubonds and Reloader 22

7828 seems to be popular, I have RL-22 and MRP, those two pretty close. I have some 140 NBT's on hand that will be first up.

PP 4000-MR and Superperformance are pretty close on the burn chart. I have both, may try them, have RL-19, as well.

My bud just gave me two boxes of Wby brass. They had it in a close out bin at Cabelas. He got them for $20 a box, or a buck a case, less than half retail ($45).

I told him, he done good...

40 cases should last him a while.

DF

Had good luck with 7828 and 140gr TSX, 150gr BT's in a MkV 270Wby.

WBY MK V Ultralightweight

My load comes out of the Nosler book. 69.5 grain of Vihta N560 with a 150 grain bullet. This is good for 3200 fps in my custom 26 inch barrel.

It has been really accurate for me as well. Lots of three shot groups have been well under moa.

Good group, Fotis.

What's terminal performance like?

DF

On game? no idea sir!

but!

I like 7828 and RL 22. Can't tell much difference in accuracy but the RL is a significant gain in velocity. I've tried H 4831 and in the past and it's ball twin H450 with good results. I have some test loads with Mag Pro waiting for decent weather to test. Hasbeen

Look forward to your report.

DF

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.

DF

Tag

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.

DF

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...

DF

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.

DF

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?

I'd trust the 130 TSX/TTSX WAY more than I'd trust a NBT at 3,500...

One would think the NAB should hold together better than a NBT, but some refer to Accubonds as accubombs...

SSII's may hold up at that speed. I've said on numerous posts, matching bullet construction with velocity is an art. A great bullet at 2,800 fps may be a disaster at 3,500 fps.

DF

The Ballistic Tip is a 3200fps bullet (according to Nosler). The 150 grain BT at that velocity works great in the 270 Weatherby. The 130 grain BT is probably better suited in a 270 Winchester.

My buddy has a .270 Win and likes 130 gr. NPT's. He was thinking 130's would shoot really flat in the .270 Wby.

I need to work out drop and energy with 130's, 140's and 150's. Sometimes higher B.C.'s compensate for slower MV. 140's seem to be popular in the Wby.

If anyone has already done that research, I'd appreciate the info.

DF

I use 140 gr NAB for Whitetails with great results. But where I hunt shots are generally at least 100 yds. Last years were 211 and 306. I am going to use it for hogs this year and am going to try Barnes 140 TSX. If they come to the feeder they are close. My buddy from Houston uses a 7mm STW with Barnes with good luck. Not sure what grain

Use a 300 yd zero on that Weatherby . 3" high at 100

I ran several loads thru Hornady's Ballistics Calculator.

As I suspected, B.C. can make up for velocity loss with heavier bullets.

I ran 130 and 140 NAB's, 130 and 140 NPT's, 150 ABLR at Load Data velocities and found the trajectories out to 600 yds. within just an inch or so except the 140 NPT (5").

My bud doesn't twist, will have a 200 yd. zero, hold 5", 10" and 15" for 300, 350 and 400 yds. respectively.

We'll see which bullets the gun likes and go from there.

DF

I took my recently purchased used Mark V(Howa) to the range yesterday. It has one of the worst stocks for cheek weld of any weatherby I owned. That said, shooting 29.99 a box factory 130's it shot under an inch. Yeah its a keeper. I cannot wait to load some cutting edge bullets to see how it does with them.
