I am shooting a Marlin 336 with Federal powershok 150 gr. Fn bullets. Sighted in 1" high at 50 yards what kind of bullet drop will I get at 100 or 150 yards? Thanks.

Federals website has ballistic info for all its loads.

Shoot and see , charts have the drop but your eyes will see as only you can . The charts come from calculations . Try on an over cast and clear days , a good shot will know !

I am going to the range tomorrow, just wanted to know what to expect. Thanks.

I would go closer to 3" high at 100 that way you will be around 3" low at 200.... This is only a suggestion... Your results may vary...

how did it go at the range ?

The range is the best way to know for sure, ballistic charts are fun, but not gospel.

I agree, 3" high at 100 yards is better.

hello;

3 inch high??? hunt pipeline lines/ power lines/ bean field?

? hunt woods?

if you hunt woods, how far can you see (distance) in woods??? 75-100yards max? nothing wrong with 100 yard zero. yes, i do hunt with a marlin 30/30.

I compromise a tad. I sight a 3030 in 2 inches high at a 100. Gives a little better poa for pushing a slug through a hole in brush up close and requires only that you hold on the upper half of a deer at 200 yards.

STUMPJMPR · « **Reply #9 on:** October 30, 2008, 01:05:06 AM »

I sight in 3" high because sometimes 200 yard shots present themselves.... This is my max range with this rifle.... I used to hunt with a 270 win and I have killed 2 deer about 150 yards out.... Most of my shots though have been around 50 yards.... I don't like to have to worry about hold over or under.... So + or - 3" is fine for me... You definitely won't miss the kill zone if you can hit what your aiming at...

Doesn't matter to me (out west or out east), the 30-30 Winchester is all the same. I like 3" high at 100 yards for myself out to 150 yards is perfect and possibly a bit further. I shoot the 30-30 Winchester in a Winchester model 55 (breakdown) and Winchester ranger (tang safety) and shoot the 25-35 Winchester in Winchester pre-64 model 94. With the 25-35 Winchester I still use the same 3" high at 100 yards.

I did not see a difference between 50 and 100 yards. Shot right on.

I used the 30-30 on several deer when I lived in Wyoming. While I had no trouble hitting them using factory corelocts and power points in 150 grain I noticed that after 175 yards or so I got little or no expansion even if I hit bone. Great penetration though but definitly needed to be ready for a second shot.

Terry, I used a Remington ballistics program using their 150 gr. Core-lokt and it shows about what you verified at the range. +.17" @ 50 yds, 0 @ 100 yds, and -2.39" @ 150 yds. I have an old Foremost (Marlin made for JC Penney) and it shoots the 150 grain sp the same at 50 and 100 yds.

I ran this cartridge info thru the Sierra program.
Showing a MV of 2390 fps it came up with one of several possibilities. I like this one.

50 100 150 200
+1 1/4" +2" + 3/4" --3"

I don't like to go any higher than 2" on any rifle for sighting in. I tryed the 3" on the 35 rem with the Leverevolution and shot over 2 deer, dropped it down to about an inch and dropped the next doe I shot at. I tend to shot high if I don't keep it down some. Most of mine are at an inch to 1 1/2 inchs at 100 yds. Just easier for me to raise up some on the body than hold low. Makes a difference on how high you are in elevation as well. Where I am is 4500 ft. to 8000 ft where I hunt. Everything flies flatter the thinner the air is. Just don't know till you go and shoot. DP

What cartridge is this?

You have heard of "rainbow trajectory?"

I had heard this Barnes TSX bullets, and I'm beginning to believe it.

I'm new to shooting with scopes, so I'm no expert. Can any body here can shed some light?

I recently range tested some Corbon, 150-grain, TSX copper in my 30 30 Marlin 336 W.

I got 1 inch groups at 25 yards, about 2 inches high. At 50 yards, it climbed to 3 inches.

At 75 yard the shots started stringing vertically, up, up and away, until they were hitting above the paper.

Has anyone experinced this? Is it shooter error, or is it extreme rainbow trajectory?

Having lived in the west all my life I've always been a +3" at 100 guy myself, but in thinking about it, if you hunt in continuous forest, how many shots are you going to blow because you couldn't reach across an clearing, as compared to how many shots you miss by shooting over a head or neck at less than 100 yards.

BBF · « **Reply #19 on:** December 13, 2008, 08:59:43 AM »

Terry:
I ran the Federal 150 gr Hi Shok as well as the other major Ammo makers thru the program. All of them are within a fraction of inches to those numbers.
If you got a specific type ammo and elevation as well as temperature in mind I can tighten those numbers up as long as we stay with the same muzzle velocity.

If you prefer a range and zero setting that gives you no more or no less a bullet strike above a certain number of inches, I can do that as well.

Terry1 · « **Reply #20 on:** December 15, 2008, 04:27:57 AM »

Cool, thanks! The ammo is Federal power-shok 150gr. and elevation would be 1" high at 50 yards. I know what it does at the range, but I wouldn't mind seeing it on paper to see how it matches up. Thanks again!

Lloyd Smale · « **Reply #21 on:** December 16, 2008, 02:12:57 AM »

it isnt shooting over an animal i worry about its the fact i hunt in thick areas of hardwoods and swamps and many times your shots need to be into a small hole in the brush or under or over a tree limb and need to be taken quickly with no time to think about trajectory. To be honest the best sight in for that kind of work is dead on at 50 yards and thats the way most of the old timmers did it and still do. But then they shake there head at me when i tell them the 3030 is adequate out to 200 and maybe a few more yards. Alot of it too is like a handgun. You need to know your gun and load. If you do a small ammount of holdover is an automatic thing your mind does. Just like a traditionaly bow hunter does with his recurve or longbow. My buddy once shot a antelope with a 3030 using 150 corelocks at 225 yards off hand with an open sighted gun. Its probably more shot then im capable of but he had probably put 2000 rounds through that gun before hunting season and knew it intimately and is a hell of a shot to begin with. Gun was sighted in dead on at a 100 yards. Hes a handgunner and spends many many hours long range shooting with handguns and doesnt believe in majic equations for sighting in a gun he believes in shooting his gun and knowing where it hits at all ranges. you might get away with not being familiar with a gun like a 300 wby or even a 270 but when you start taking shots at long range with a gun like a 3030 or 4570 youd best know your gun and load.

Didn't mean to hijack your thread. But my question seemed relavant.

I'll start a separate post, and maybe that will avoid confusion.

Thanks,

Terry:

I can find a listing for Hi-Shok but not for Power Shok.
If it is the same load/bullet here is what I get for a MV of 2390fps

50yards +1" 100= +1.75 150= + 1/4 175= --1.5 200= --3.75
