Re: 270 trajectory

Great info Sir, I think I might be getting it Thank you very much. Now you made me think of another question. Is not 400yds long range. i have killed ground hogs out to 357yds and .i shot a crow at 286. I also have a 22 win mag and I have shot many many squirrels out to 65 yds all head shots. You said when i start shooting long range. What is considered long range. All the formentioned shots were under hunting conditions. Not off hand of course I do use home made shooting sticks.Hope i have not opened a can of worms. Again, thank you very much.

Your question should be conversation starter......Long Range is different things for different people and different conditions.

Just my thinkin' here. Change cartridges, game, new neck of the woods, etc. it all changes, at least for me.

270 Win
Generally 0-300 yds short range
300-500 moderate range with my 270 Win
500-800 long range w/270Win (due to traj and energy.
This is post LRF, anti cant device and much better scope.

270 Allen Mag
0-300 yds short range - that's the longest distance on the local range
300 - 800 moderate range
800 - 1200 long range
Greater than 1200 - Out Of Range.

Head shots on squirrels @ 65 yds is pretty good shootin

Like Roy said, LR is different to different folks, but I would have to agree with his general assessment of the 270 Win.

I'm new to this game and my personal longest shot was a paced off 425 yds on an antelope with a sporter 7mmRM. It was sighted in about 2 1/2 inches high @100 yds and shooting a 120 gr Sierra at about 3400 fps. I was guesstimating the range at 450 and I guesstimated the wind to be about 15 mph almost direct cross. I held just above the tip of his nose and the bullet struck the base of the back of the neck. I was hoping for a boiler room hit, but it worked.

In a 270 Win, zeroed @ 200 yds, your bullet will drop 6 inches at 300, 19 inches at 400 and 39 inches at 500. the point being, once you get out past 300 or 400 yds, judging distance becomes critical. A 50 yd miscalculation will likely result in a miss and even a 25 yd miscalculation could result in a miss. So 3 things you need for LR hunting are, an accurate rifle, an accurate range finder and a good quality scope that has the type of reticle to make accurate holdovers or reliable and repeatable turrets for dialing your windage and ellevation.

One other thing to consider is bullet terminal performance. You want your bullet to have enough velocity to expand on impact and enough momentum to penetrate vitals and hopefully exit. This is how I determine the maximum ballistic range of my cartridge. Me and the rifle are the other part of the equation.

Good shooting and hunting,

-MR

1) Lack of practice at that distance
2) Lack of confidence in my wind reading abilities
3) Limited to using 140/150 class bullets. When the 170gr Wildcats become available again the whole deal changes. Even with them I would be very careful of the shot being taken at beyond 1100-1200 on an elk. Deer no problem.

The 1200 limit is for large game.
I have smashed some trophy rocks at 1400 plus but they don't have hair, antlers. or other things that get the ol' heart rate up. Plus you know they are going to stay there.
