devinv Report post Posted June 19, 2007 thanks a lot RR for helping out, ill try a few different loads and see what comes up shooting best out of my rifle, if anybody else has any experience with the hornadys, they have a few different loads in 150 gr, didnt quite get the difference between the sst, the light magnum, and the soft point, then they have the sst light magnum..

Hooked_on_Coues Report post Posted June 19, 2007 The Hornady Light Magnum is the most accurate factory round I have found. I shoot sub one-inch groups with the 150's out of my '06. I stopped handloading for it but, beauty of handloads is you get to shoot alot more rounds for the dollar. Better to have an inch&1/2 rifle you shoot alot than a 1/2inch rifle that sits in the corner. Share this post Link to post Share on other sites
az4life Report post Posted June 19, 2007 I'd still say start short (50 yds to 100) and them go longer. Unless you really know you will be shooting no less than 300 yards, I'd not recommend you zero at 300yds. Zeroing at 300 yards has a lot more difficulty to get good groups. Unless you know you won't be shooting less than 300 yds, why waste the time and effort. If you zero at 200, or 300, the difference in point of impact at 300 or 400 or even 500 is not enough to cause a miss from 1 to another in most flat shooting calibers. I saw something on another topic that you should consider. 99% of the time what is the distance you will shoot? Now consider, What distance will you regularly practice shooting? If your answer is 250-300 yds,by you care not going to be able to shoot 600-700 just by zeroing at 300. Food for thought, and for the shot.... Share this post Link to post Share on other sites
devinv Report post Posted June 20, 2007 did some more searching, decided on a few loads to test out, i didnt want anything ballistic or to act like a ballistic, and i wanted a 150 gr, so that eliminated the hornady sst and interbond, as well as the nosler accubond, it left me with the winchester failsafe 150gr and the hornady 150 gr light mag soft point, i wanted to try the nosler partition as well, but i cannot find loaded ammunition, just the bullets to reload with, anybody know if they make a loaded round with this bullet? i saw that federal used this bullet but it was 165 and 180 grain? also, i cannot seem to find the winchester failsafe in a loaded round as well, is this the same problem?

bobbyo Report post Posted June 20, 2007 Devinv, I have had similar problems as you sighting in. My symptoms were identical to yours. After many different rounds, bruised shoulders and expensive scopes. I realized that the wandering was due to an over heated rifle. I don't think you will find a magic round that will fix the symptoms you describe. I have two suggestions. First, as already mentioned(azforlife), you need to take time inbetween rounds. I shoot three round groups then let the rifle cool for ten minutes. This is not very time efficent, but you will notice that the bullet will not wander. Second I think the wandering may be due to stock contact after the barrel heats up. Getting your rifle bedded and your barrel free floated or Pressure bedded could solve the problem. I believe you can still get a bedding job from a reputable gunsmith for just under a 100 dollars. Which in the long run will save you money on ammo. You could do it yourself. There is alot of info on the web. The sight below explains what I am trying to say a lot better. http://hunting.about.com/cs/guns/a/float_bed.htm Also like ichiban43 i sight in at 25 yards for all my rifles. I don't move it once it is. I do this for three reasons. 1. makes sighting in easy. 2. Twenty-five yards will put most rifles close to their point blank range. 3. When i ride my rifle down the hill out in the field it is real easy to resight in my rifle. This has eliminated the ballistic chart in my head when the moment of truth comes.

Outdoor Writer Report post Posted June 20, 2007 2. Twenty-five yards will put most rifles close to their point blank range. Bingo! I've sighted my rifles like this for 40-plus years. With a fairly flat-shooting round, you'll be high from 25 out to somewhere between 250 and 300 yards, where the bullet will again be at zero. From there on out it's below line of sight. This will usually provide about 8-10" point blank zone with the bullet hitting anywhere from 4-5" high to 4-5" low from 0 to 375-400 yds. Your mileage will vary depending on the caliber. -TONY Share this post Link to post Share on other sites
ichiban43 Report post Posted June 20, 2007 Check out the trajectory chart that I posted earlier in this thread. I learned to site in a rifle this way so many years ago--I won't go there. Then "re-learned" it in the Army with the M-14 (308 Win). it has never failed me. I picked up a laser boresighter and love it. It beats the old cradling the gun in notches in a cardboard box and looking down the through the barrel. Trying to adjust the scope without moving the rifle is frustrating. For any of you interested in "long range" shooting, the July issue of NRA's American Hunter has a fairly good article on it by Ian McMurchy--he has done other articles too-Google him up if your interested. A good read and has some informative techniques. Share this post Link to post Share on other sites
Outdoor Writer Report post Posted June 20, 2007 Check out the trajectory chart that I posted earlier in this thread. I learned to site in a rifle this way so many years ago--I won't go there. I had seen your chart earlier, which of course wouldn't pertain to every caliber. One thing I didn't mention in my other message: I generally sight 3/4 to 1" high at 25 yds., thus the figures I gave. Doing that gives me a zero farther downrange, as Doug had suggested earlier in this thread. Having and KNOWING your point-blank range almost eliminates the need to hold under or over on larger big-game animals as long as you also know where the vitals are and can shoot accurately. Of course, you also either have to judge ranges well or use a rangefinder in some situations. Lastly, even if you sight at 25 yds., it's always a good idea to then shoot at the longer distances because each rifle and caliber might react differently than what a ballistics chart/program will tell you. -TONY Share this post Link to post Share on other sites
Outdoor Writer Report post Posted June 20, 2007 The two computer-generated trajectory charts below were set-up for a 300-yd. zero, as Doug had suggested. I pasted the figures out to only 400 yards. The first is for my .264 mag shooting a 140-gr. bullet and the second is for my son's .270 with a 130-gr. bullet. The third column is the impact point. Note the approximate zero distances in the bold numbers. And...another thing worth noting is the similiarity of the .264s ballistics to the .270, albeit with a bullet that is 10 grs. lighter. The energy data isn't very different either. Both have a point-blank range out to about 370 yards with an 11" or so impact area. -TONY .264 -- 140 gr.

Tony, If I raised my 25 yard zero up 3/4 of an inch it would zero my rifle 7 mag at 400, but I would be 6" high at 100 and 9.4" high at 200 yards, 7.6 at 300 yards. Trajectory would be very similar for my 270 and 243. That would be too much thinking for me and why I prefer to print Dead center at 25 yards which gives me a 0 sight in at about 250 yards and a hold on the body out to 325-350. For farther shots I have hold overs written on my gun. Share this post Link to post Share on other sites
Outdoor Writer Report post Posted June 20, 2007 bobbyo That'll work just fine. As I had said earlier, your mileage will vary, and for the flatter shooting calibers, dead on at 25 is good. That's about what the .264 and .270 charts I posted show with actual zeros between 20 and 30 yds. The two KEY factors are KNOWING the range and where the bullet will hit at that range. And wind drift, which can be substancial at the longer ranges, also plays a BIG part. What weight bullet are you using -- 165? -TONY Share this post Link to post Share on other sites
bobbyo Report post Posted June 20, 2007 Tony, I use 150 core-locts in my 7mag for deer. My gun likes them and they are the deadliest mushroom in the woods. Bob Share this post Link to post Share on other sites
Outdoor Writer Report post Posted June 21, 2007 Bob, That's a good bullet. Although I shot 10 of the 12 critters I killed in Africa with my .264, I used 180-Core-Lokts in my .300 Win mag for the other two. And I have 3 boxes of 140- grainers sitting behind me that are for the new, never-fired Rem. 700 Ti in 7mm SAUM that I want to sell. -TONY Share this post Link to post Share on other sites

Outdoor Writer Report post Posted June 22, 2007 Tony- With a 30 06 and a 165 grain bullet what would you sight in at 25yrds? Thanks . This would be one of the loads I would sight about 1 inch high at 25 yards. You didn't provide all the info, so I used a factory round with a MV of 2,800 fps, 165-gr. spitzer bullet with .407 bullet coefficent at an altitude of 2,500'. Your first zero would be at 12-15 yards and the downrange second zero is 250 yds., and it basically gives you a nice 8-9" point-blank range from 0-300 yards. The second chart is for a 25 yd. zero, which is about like sighting in for 100 yards. -TONY 0 2800 -0.75 10 2774 -0.11 20 2754 0.49 30 2733 1.04 40 2712 1.55 50 2692 2.01 60 2672 2.42 70 2652 2.78 80 2631 3.09 90 2611 3.35 100 2591 3.57 110 2572 3.72 120 2552 3.82 130 2532 3.88 140 2513 3.88 150 2493 3.81 160 2474 3.7 170 2455 3.53 180 2436 3.31 190 2417 3.01 200 2398 2.67 210 2379 2.26 220 2360 1.79 230 2341 1.25 240 2323 0.66 250 2304 0 260 2286 -0.72 270 2268 -1.52 280 2250 -2.38 290 2232 -3.31 300 2213 -4.31 310 2195 -5.39 320 2177 -6.53 330 2160 -7.74 340 2142 -9.03 350 2124 -10.4 Zero at 25 yds. 0 2800 -0.5 10 2774 -0.27 20 2754 -0.08 30 2733 0.07 40 2712 0.17 50 2692 0.21 60 2672 0.21 70 2652 0.17 80 2631 0.07 90 2611 -0.08 100 2591 -0.27 110 2572 -0.52 120 2552 -0.83 130 2532 -1.18 140 2513 -1.59 150 2493 -2.07 160 2474 -2.59 170 2455 -3.17 180 2436 -3.8 190 2417 -4.5 200 2398 -5.25 210 2379 -6.07 220 2360 -6.95 230 2341 -7.89 240 2323 -8.89 250 2304 -9.97 260 2286 -11.1 270 2268 -12.3 280 2250 -13.57 290 2232 -14.91 300 2213 -16.32 310 2195 -17.8 320 2177 -19.35 330 2160 -20.97 340 2142 -22.67 350 2124 -24.45 Share this post Link to post Share on other sites
