A 100-percent copper bullet with a polymer tip to boost ballistic coefficient to improve long-range ballistics and provide fast expansion. The four razor sharp cutting petals double the bullet diameter that wreak extensive internal damage and produce massive wound channels. The TTSX is extremely accurate and has great expansion.

Hammer Bullets™ are turned on a CNC lathe and use a unique solid copper blend that is designed for maximum terminal performance. Each bullet is weighed and micrometer measured as it is produced. The result is an incredibly consistent product with unparalleled quality control. The hollow point design, initiates expansion upon impact, shedding petals immediately, with the remainder of the bullet staying intact with a blunt front for optimal wound channel. All Hammer Custom Bullets are designed to optimize Weatherby’s flat shooting cartridges.
Take a deeper dive into Hammer Bullets with our On Our Mark podcast. We sit down with Bryan and Steve of Hammer Bullets to talk about the performance and what makes Hammer bullets different from similar projectiles.

The InterLock® features an exposed lead tip for controlled expansion and hard-hitting terminal performance. A secant ogive design — one of the most ballistically efficient profiles ever developed. The raised ring inside the jacket is embedded in the bullet, combined with the one-piece core, keeps the core and jacket locked together during expansion to retain mass and energy.

Bought a 270 Wby Mag Alaskan (NIB) about 15 years ago. Sighted it in to print 3″ high at 100 yds and it has held its zero for at least that long. I always fire ONE round (ditto the $5.00 trigger squeeze mentioned by the previous poster) before each hunting season here in CO and the lone bullet hole in the paper has NEVER moved – 12o’clock at 3″ high! It’s one awesome caliber and has taken over a dozen elk and at least twice that number of mulies over the years. Oh, yeah, silver Leupold 4x-12x glass in Leupold mounts. Great looking outfit!
Capt. Dave –
I absolutely live my .270 Weatherby. It doesn’t have a tremendous kick. It us exceptionally accurate and has a load of power! Extremely flat shooting!
Jim Fallis –
I shot my first buck in 1979 at 12 years old using my Dads Weatherby .270 mag MarkV Deluxe. To this day I currently own (2) MarkV .270. 1980 MarkV Deluxe and a 1992 MarkV Weathermark. I mainly hunt mule deer in the west. That .270 mag always drops them in their tracks. So flat shooting and hard hitting. When out hunting it’s a point aim drop out to 400 yards. No range finder no messing around put hair in the scope and squeeze!!! Not many people know about the old .270 mag but it’s perfect for me over the last 44 years.
C Jones –
Have had my 270WM for over 40 years still my workhorse rifle. I want to share a stupid mistake I made at the range. Put a 270 Winchester in the 270 WM and fired. The case expanded and ruptured blowing the side of stock off. Bullet went down the barrel since it was the same size and even hit the target. I’m telling this to let you know how strong the action is. Got a new stock and everything works
James O’Donnell –
My father bought his 270 mag around the time I was starting school maybe 1961 or 62 it was responsible for for the family needs to this day. It was the main stay for the family and was responsible for 100’s of moose deer and elk for the last 60 years. It can still hold a 1 inch group after all this time. (thank you Wheatherby .)
Daniel Wallinder –
I bought my 270 magnum When I was in the Air force stationed in weisbaden Germany for 200.00$. Yes the shells are exspensive we now live in Athol Idaho. I hunt on our 10 acres built a shooting range to protect me. Had it inspected from sheriffs dept Cdl Udaho was told it is better than they qualify at. I shoot deer,elk,and turkeys. I wish we had hogs

‘Hard hitting’ an under statement! I have a 7/16th X 8″ gong made out of AR500. Been shooting BCPR and larger caliber pistols and rifles at it for a dozen years.., Rifles always at a minimum of 100 yards and all of the loads just splatter or bounce off. EXCEPT one time my friend brought his 270 Weatherby magnaum rifle and put two holes clean through the AR500 (harden steel)…
Andrew M Zdobylak –
Well, all I’m going to say, it’s the only rifle I carry afield for the last 30 years. And, for some strange reason, I became a hand loader. Go figure.
Jerry –
Accurate, accurate, accurate! My no.1 , go to rifle.
Have owned mine for 20 yrs. Great for any game in U.S.
Wouldn’t trade for anything else!
Rick –
Have used this Rifle since 1993, will down anything that walks, swims or crawl in the United States, Never been disappointed, mounted with a Burris Black Diamond, would not consider another.
Wenas –
Accumark is the best rifle I own

I have owned several .270 WM Mark V, first one was a German built early Weatherby’s, unfortunately that weapon got stolen. Bought another several years back as I just love that gun and cartridge combo. Both of them were/are very accurate, with many animals harvested and just plain enjoyment from shooting it. Ammo like most things has become expensive even for this breed, but reloading is great and fine tuning the set up is great as well. I enjoy several other Weatherby’s, 257 WM, 30-378 WM and look forward to the new Stud on the block, 6.5-300 WM!
Len –
i have used my 270 Weatherby mag for over 20 yrs now and have shot every Canadian game animal their is without any disappointment. from Grizzly to coyote i have downed them all without multiple shots. I highly recommend this rifle to anyone who can afford one. They are virtually trouble free for life.
Big Jim –
Outstanding quality, accuracy and value.
The first 3 rounds I fired,after sight in, harvested a large Whitetail buck, a 250 pound hog and a head shot on a turkey at 80 yards.
This is my favorite rifle of all time. I wouldn’t use anything else
Speed Accuracy –
270WM is Plenty gun for any Big Game in NORTH AMERICA
Long dick johnson –
I have hunted my whole life and bought a 270 wby mag about 15 yrs ago. I have killed elk, hogs,mule deer, blacktails,coyotes and wouldn’t hesitate to shoot anything else with it. I have shot deer and hogs at ranges exceeding 550 yds and have never been disappointed. Extremely flat shooting and accurate! I absolutely love this rifle and highly recommend it to anybody. I recently handed down the gun to my son for a graduation gift and went and bought myself the same gun with an accumark stock and stainless steel fluted barrel..
Michael –
I love my 270 and have used it for years.
birddog –
A great flat shooting round with mild recoil and plenty of power. I bought my first 270 weatherby mag after shooting many calibers over the years I was amazed at how accuate and powerful with mild recoil it was. I have shot other 270 that kicked harder.
Ron –
Took my Weatherby 270 with me. The trip was only to refill feeders and reset hog trap. When we saw the herd of hogs run by at slightly over 100 yards, my friend said “get your rifle, they always run back the way they came”. They did. 3 quick shots dropped 2 hogs over 250 pounds and one oven size hog also. My gun operated smoothly and hit all 3 targets where aim was placed. All hunting shots taken have been productive. My Weatherby Vanguard is favorite of all guns I own.
elky007 –
Have harvested many big game animals with this caliber at both close and far range. ( Far for me meaning between 400-500 yards) Took down a large mule deer buck this fall using a 140 gr. Accubond. Bullet performance was outstanding, retaining a large percentage of its mass. Would love to be able to post a pic of the bullet recovered. Have always appreciated the quality and consistency of Weatherby ammunition. If any down side, the $5.00 per trigger pull would be my only complaint.

Having grown up on.30 cal rifles the transition to this caliber was a windfall of sorts. I drew a ram tag in my home state of Colorado and a trip to the sheep and goat expo was in order. Bought one ticket for a Weaver custom 700 in .270 wby no less and won this draw as well. This rifle and caliber proved outstanding. After 2 and 1/2 weeks I found my ram in a bowl just below 13 k I the continental divide, about 20 degrees uphill and lasered 328 yards. A chip shot for this combo. The 3 Bulls have been taken farther… and again this caliber does not disappoint. Mild recoil and groups that are very sub Moa have left old meat in the pot in the safe at home. Can’t offer a better endorsement.
