Barnes bullets have just about the worst BC possible especially in their 7mm offerings which are only flat base on top of that. Use any other bullet but Barnes in 168gr or heavier and the 7mm mag will walk all over the 270. heck even a high BC 140 in 7mm will out perform your 140 Barnes at 3200 fps. I have nothing but great things to say about a 270 but to call it the equivalent of a 7mm mag is just wrong.

Similar cartridges like the 7 mag or 300 win mag, 7-08 or 308 or .270,.280 or 30-06 need to be compared the same way. A 150 grain bullet in a 270 is a heavy for caliber bullet. A 150gr bullet in 7mm is a middle weight at best and 150gr in a 30 cal is a light weight. To accurately compare cartridges you need to use heavy for caliber bullets in all of them. A heavier bullet maximizes potential of the caliber and why a 270 shooting 150s can be made to look like it can perform just as well or better than larger calibers. Make comparisons with 7mm bullets in 168-180gr weights and 30 cal bullets in 200+ grain weights. Also make sure to compare using similar bullet styles and accurate BCs.

Yes it will be off. Altitude, pressure and temperature will all have an effect on ballistic performance. The easy way is once you have a ballistic chart that closely matches your actual shot data is to calculate another chart for a specific elevation and compare the two to see how much things actually change. The sure way is to actually shoot at distance at a certain elevation and record actual shot data.

250 Savage. Accept no substitutes. If you like fast and flat you can run 70-75gr bullets at 3600 fps or load the 115 berger and use it for everything. I have moved away from smaller calibers for coyotes I always had to many runners. They don't run from the 250.

I have a shooting chrony and it works just fine. The magnetospeed looks awesome and probably works great but I don't think its worth the kind of money that they want for it. The trick to using it is not using it until you have found a load your rifle likes then strap it on and find your data. I do the same with a standard chrony. I don't even get it out of my range bag until my load is developed and proven, then it gets run over the chrony and ballistic calculations made.

Wow nice buck Scotty. Good job man.

Nope never flipped the bird to another motorist. Just shake my head grit my teeth and move along at the posted speed.

I will never understand grammer Nazis. I get that its a pet peeve but you understand what is trying to be said. Read it, shake your head and move on. I don't go around cutting retard drivers off making them come to a stop ripping them out of their vehicles slaming their face into a speed limit sign so I'm sure they have seen it then drag them back to their vehicle by the hair and showing them how the gas pedal works because they drive slow. Lord knows I would like to but I don't.

6.5-06 ackley, 260 rem, 6.5 creed, 6.5-284. Pick one it don't matter, they will tackle anything you point it at and do so with aplomb. 140gr bullet for everything coyotes to bull elk it can get it done and it doesnt require a brake or 90 grains of powder.

Loaddata.com only lists data for 70-75 grain bullets in the .243 with superformance powder. Start loads of 45 grains and a max of 49. I would start somewhere around 42 grains and work up for a 95.

^^^What he said.^^^

Yes there are books out there. Applied ballistics for long range shooting by bryan litz is an outstanding resource with tons of useful information. Bryan is also a member over on longrangehunting.com and has posted data sheets on numerous bullets he has tested including the new Nosler accubond long range. He has a very in depth and scientific approach to measuring BC and he does so over long range by pulling the trigger himself. I highly recommend the book just for the accurate bullet data alone. There have also been various articles written about over inflated BCs in publications like varmint hunter magazine where the air force academy has tested numerous bullets as well with similar results. To summarize Nosler bullets are the most over estimated of all major manufacturers as they prefer computer calculations and extreme velocities to determine their bc. The new Nosler long range bullets are very good and a definite improvement over the standard but you can't trust what is written on the box or online.

Better check your facts on Nosler before you pick a bullet based on BC numbers. The standard 140 accubond has an actual BC closer to .465 vs the advertised .496. The accubond long range is even worse. The litz measured BC is .543 vs .625 advertised. If you are using noslers numbers for calculations of energy your going to be a ways off. The best bullet going for the 270 in my opinion is the berger 130 classic hunter. With its hybrid design it boasts an actual BC of .497 which is higher than the 140 vld and only .031 lower than the 150 vld plus it can be driven much faster than the heavier bullets. Using standard conditions this bullet will maintain 1000ft lbs of energy out to 665 yards at a muzzle velocity of 3000fps

I'll take it. Pm sent.

I saw the most deer in behind sunglow ranch last year. None of them had horns but there were plenty of deer.

As far as caliber goes 260 all the way. A 140gr bullet will tackle anything your wife would wish to hunt and do so with very little recoil. The savage trophy hunter would be a good one to start with. Light weight and accurate right out of the box.

Send it off to E.R. shaw. Hands down best bang for your buck.

Probably has more to do with the bullets used and shot placement. Back east bow hunting is much more prominent judging by 9 out of 10 hunting shows being filmed bow hunts. If you notice most rifle hunts we do see are sponsored by Barnes or nosler. Couple the fact that shots are rarely more than 100 yards placed behind the shoulder in a typical arrow placement using bullets designed to poke a hole fired from a magnum rifle with really high velocities into a deer less than a foot wide at the ribs equals a lot of energy expended into the dirt behind the animal. I think what we are seeing is the bullet not having time to open up and work properly in the soft tissue of deer resulting in a deer running a ways before they even realize they are dead. In episodes ive watched where the hunter takes a quartering shot or puts it through the shoulders results have been better and quicker due the bullet working better in more animal. Just my thoughts.

Maximize potential with a heavier bullet. Your shooting a RUM because you wanted more performance and horse power might as well get all you can from it. It would be 200 grains or heavier for me. Light weight 30 cal bullets have horrible BCs and bleed a lot of energy and velocity very quickly.

Send it off to E.R. Shaw. They will true the action lap the lugs and rebarrel for a very reasonable cost.

I like a two piece on a hunting rifle especially if it has a blind magazine and you have to unload the rifle by cycling the bolt. Shouldn't need a 20 moa base on this rig at all especially only out to 600. I would suggest getting a set of the Burris signature zee rings that come with additional 10 moa inserts. That way you have the option of adding more if you need it.

The way to measure scope height as outlined in applied ballistics for long range shooting is this. Measure the dia of your scope bell and divide by two. Measure the dia of your barrel at the end of your scope bell and divide that number by two. Then measure the distance from the bottom of the bell to the top of the barrel and add them all together to get your scope height. Most scopes with 50mm objectives end up being at least 1.8 if not a bit more. That all depends on scope design and ring height.

168gr or heavier. I really like the 168gr berger H4831, H1000, Retumbo and Ramshot magnum should all give you good results.

H4350 is the go to powder. Start at 41 grains and work up.

Deer and pigs don't need a magnum. Standard .270 any of the 6.5s or the .25-06 would be just about perfect. Honestly if I were to have a magnum it would be one in .30 cal pushing the heaviest bullet possible to maximize potential. After all people get magnums to have better performance, just as well get it all.
