7saum Tikka 169 Hammer Hunter (HH) or 168 Cutting Edge MTH instead of 145LRX for Deer and Elk?

[steffen707]

i'm putting together a Tikka in 7saum with 18" proof CF 1:8twist barrel. I was thinking this whole time of using 145gr LRX because I didn't know Hammers and Cutting Edge Bullets existed. When I read people using Hammers, I never thought they were a possible better than Barnes LRX alternative.

It'll be easier for the longer BC bullets to maintain speed and keep above 2000fps on target up to 600 yards than the LRX. From my calculations it would be tough to keep the 145LRX above 2000fps at 500 yards, let alone 600.

I've never shot at game over 400 yards, but I'd like to be able to ethically with a mono copper.

Any opinions of the 168-169gr Hammer Hunter or Cutting Edge MTH for 7saum for deer and elk?

I killed 2 deer, 2 elk and a pile of coyotes with the 169 Hammer Hunter this year. They are super accurate and performed great. They had a muzzle velocity of 3300fps out of a 28 Nolser with 26" barrel. So just try to figure out roughly what velocities you'll be getting and use a ballistic calculator for your elevation. BUT, they have a trued BC of .24 G7. So use that in your calculations. Also, the 155 Hammer is another great option if you want more close range velocity.

Monos need speed. 18” Saum is going to be slooooowwww. The 145LRX is a great choice. If you want to go hammer then something in the 143 would be your best bet. If you’re shooting a 28nosler then I think those heavy monos make sense.

With a MV of 2800 the 169gr hammer hunter should still be 1921fps at 600yards.

Do you think 2800mv from an 18" 7saum is attainable with 169gr bullet?

Their site says .285, you're saying they're ACTUALLY .24 on the G7? Any idea what the true BC of the 155hammer is?

with a .24 G7 at 2800fps, it would only be at 1776fps at 600 yards, so that wont work. Maybe I should go to the 155.

Well screw it, i ordered the 155 Hammer Hunter, 168gr Cutting Edge and already have a box of 145 LRX.

i'll shoot em all over the chrono and then fine tune what weight I want to ultimately shoot.

Anybody else take game with the Cutting Edge bullets?

The owner of hammer recommends the 143 with the Saum.

The 155 was .23 G7 out to 600 yards with my dad’s rifle.

Shoot, that also wont work.

How do you calculate that anyway?

Do you have to back into that number with:
chrono'ed muzzle velocity
155gr bullet
600yards MOA adjustment needed
and then calculate for the G7?

Shot drops, and none of them are accurate. Applied ballistics tested a couple and posted the actual g7. The owner of hammer told them they didn't know how to calculate the ballistic coefficient.

Yeah exactly. Known muzzle velocity and true the G7 with real world drop calculations.

lol I know mine were off for sure. Do you know where to find what AB found the BC's to be?

They were on the long range hunting forum but that thread seems to be missing now
There are quite a few on the applied ballistics app

I have a new 20" barreled SAUM that I have shot the 140 absolute hammers and the 146 hammer hunters out of. I don't have the velocities in front of me but the 140 was pushing around 3200 with no pressure and I want to say I started seeing pressure with the 146 just shy of 3100. Both grouped well, I plan to use the 140 absolutes and a second bullet like the 162 eldx for longer range applications which were over 2900 MV with no pressure. Hoping the zeros are relatively close and can be adjusted for easily.

As for the BCs I haven't really stretched the legs on the saum but loaded 199HH in my 300winmag and the BC was close out to 600yds, I just tweaked my muzzle velocity a bit and that has done the trick. My understanding from hearing it from some experts it is best to adjust your MV as long as your BC is fairly close to compensate for elevation within normal shooting ranges say out to even 1,000yds.

What powder were you using?

@Ucsdryder H4350 for the 7saum and H1000 for the 300WM

I don't have their app. Sounds like it's probably worth getting.

I shoot a 20” saum. 169 hammer, 3.050” coal, h4831sc. 2950 fps

I really want to try some other mono copper bullets other than Barnes however the BC of coppers dont even come close to the BC of modern lead core bullets. BC is everything past 500 yards.

If they can manufacture a bullet like the Absolute Hammers with a higher BC that would be money for short barrel rifles.
