270 Win. for hogs at 300-400 yards?
@ 07:21 am (GMT) |
Daniel MooreHey,I love the available information on this site,excellent job.Im just becoming interested in long range hunting and currently own a Rem. 700 ADL made in 1991 with wood stock and a Nitrex TR-1 4-16 by 50mm scope.I bought the rifle used(barely)from an old gunsmith who had lightened the trigger pull and bedded the stock.From sandbags the rifle will shoot 1/2" three shot groups at 100 yds with Winchester 130 gr factory ammo.Im just getting into reloading and it seems like there's some good BC's in the 150 gr. weights for the .270.Any opinions on how well this setup could work on hogs and deer at long range,or is the 7mm Rem. mag that much better?Thanks for any advice. |

Bruce HollerRe: 270 Win. for hogs at 300-400 yards?If you do your job, you should have no problem taking hogs at 300-400 yds. with the 270 Win, 150 gr bullet with a BC of .481, 2900 fos. There is great ballistic calculator at www.biggameinfo.com Optimal game weight for the above is 351 lbs. at 400 yds. an 823 lbs. at the muzzle. Max Point blank range is 288 yds when zeroed at 244 yds. (+/- 3"). I am going on my first hog hunt on 8/24 and am using 7mm-08, 140 gr Win power point, 2800 fps, BC .392, OGW 642 lbs at the muzzle and 253 lbs at 350 yds. Max Point blank range is 273 yds when zeroed at 232 yds. To me 300 yds is a long shot. --Bruce |

Bruce HollerRe: 270 Win. for hogs at 300-400 yards?Nathan has a great write up on the 270 on this site, look under resources. I found his section in how bullets kill very informative.He really knows what he is doing. --Bruce |

Nathan FosterRe: 270 Win. for hogs at 300-400 yards?Hi Daniel and thank you Bruce.I would prefer to see you utilize the 150 grain bullet weight for pigs at all ranges. Both the 150 grain SST and Partition are very effective at the ranges you intend to shoot to. For dedicated long range work, either the 150 grain SST or 150 grain Speer BTSP are the way to go. The Speer is the softest of the three projectiles and is fully frangible, though penetration at medium to low velocities is still quite deep. This is the least finnicky bullet to reload for, not overly sensitive to seating depths, usually easy to develop accurate loads. The SST is more finnicky to work with, it can pay to experiment with seating depths, starting load work at a bullet jump of 10 thou, then developing test loads and if no truly accurate load is found, selecting the most accurate load (lets say the most accurate load was 1.5"), experimenting by changing the seating depth to 20 thou and then 40 thou. The SST works well on tough pigs where the shild thickness is between 1 and 1.5" of cartilage. The SST is tough enough for close range work and its relatively high BC and fast expansion allows it to perform well at long ranges. I do prefer to anneal the 150gr .270 SST (see annealing videos in knowledge base) for use on boar and have had some extremely good experiences with this set up in worst case stituations when hunting mature boar which placed great demands on the bullet and cartridge in general. The Partition is generally easy to load for too. If you have a good rifle / accuray platform, the Partition will respond. I can't fault the Partition apart from its price, a factor that tends to effect hunters outside of the U.S due to fluctuations in the dollar, import levies, that sort of thing. Ideal powder charges will be up in the vicinity of 54.5gr H4350. Your old Remington should handle such charges easily but if you check the manual, you will note that my 54.5gr figure is way over the manual listings. It does pay to take heed of the manuals, work up loads carefully studying pressure signs. I generally work up to 55gr but I know what I am looking for. You will need a bit of time to get your head around all of this. Optimum velocities for your rifle will be between 2920fps and 2950fps. That said, if your rifle likes a slower load, go with it, even if its 2700fps, just go with it. Simple things like annealing the SST to soften it can make up for lost velocity or using the Speer BTSP. In other words, if you can get the velocity- great, if you can't, don't worry. Your Weaver Nitrex scope will need investigating. I would like to see you dial in your shots past 300 yards, pigs are not a huge target at long ranges, much of the target can be hidden by ground cover while the top 3" of a pig is dorsal vetebrae. Use the sight in methods Bruce suggested inside 300 yards (in other words sight in 3" high at 100 yards). Weaver scopes have a quirk in that the clicks are neither true to MOA or inches. Your scope is a sub brand that was made using Japanese tooling, what is unknown is which tooling was used. So you will have to do some tests and work out the actual calibration of the clicks. The easiest way is to use your current Winchester ammo, shoot a group, then dial up 10 or 12", shoot another group and see what happens. Then work out the error if there is an error. If your scope is not a proper target style scope lacking resettable target turrets, you may still be able to mark your turrets and use them anyway. 400 yards is not such a long way that you need a great deal of information on the turrets. If you do have target turrets, once you have calibrated the scope, corrected errors and so forth, you may eventually wish to use your .270 out to 650 yards or so. But that I think is a little way down the track for you. If you are just getting into reloading, you'll need to walk before learning to run. Don't forget to send autopsy pics once you're up and running. |
