270 Winchester reloading question
I have a reloading question. I have a new Rem. Model 700 270 Win. I loaded Nosler 130 gr. BT with H4831sc at 59 and 55 grains and with H414 54.5 grains. I cannot get better results than 1 1/2 inch groups at 100 yards from a benchrest. I checked the overall length of the rounds to conform to the rifle. Actually, the best groups are with H414. Does anyone have any suggestions to improve the results?
Thanks,

Try another load. Try different grain bullet.

Load workup procedure should include approxamitly 10 steps between Min and Max book.
You said OAL to conform with the rifle, how do you mean that? Oal at book, OAL to set the bullet into the rifling, off the rifling by 0.xxx", OAL to max for magaine, or other?
How does it shoot with factory ammo?
Scope bases, rings and mounts tight and square? Rifle bedded? Free floated? trigger work done?
How does it proform with a known good shooter, compaired to your results?
Some guys like a mag full of lead, I still prefer one round to the head.0 -
If you're not worried about velocity,a good load that works for me is 43.5 grains of IMR 4064.It slows the bullet down a little but this load has been very accurate for me in several rifles.Besides that the deer killed with this load didn't know how fast the bullet was traveling.Good luck,Bob. 0 -
Yep, you can't just pick a load and expect it to drive tacks. You have to work up a load for your rifle. Pick your components and powder. Using your manual, load 5 of the starting load and go up by half a grain of powder, loading only 5 rounds of each weighed charge and keep 'em separate, until you get to the max listed. Go to the range and fire 'em from a solid bench rest to see which load shoots best. 0 -
Stoney point makes their "overall length" tester. This device lets you take any slug in the caliber for the cartridge that you are testing and find the maximum overall length for that bullet. Then you back it off .03/.07" and start loading. These are not expensive and have made my reloading much more productive. The other two must have tools that I have added to my gear are a chrony F1 chronograph and a RCBS casemaster. If you can meansure the velosity and how straight your load are being built then you can really tallk about what is going on. Without numbers it is all mumbojumbo. The case master probably has done more then the other two combined. It measures the runout of both the brass and the loaded slug (two different measurments at different time). If you know for fact that your sized brass is straight to +/-.002" and the loaded cartridge is straight to +/-.004" and you know you powder charge is good also then you will know that your reloads are pretty damm good. Way back when I used to wonder why some of my rifles shot so much better then others. Well it turned out that some of my dies did a much better job then others. Good luck......
ps: please pardon any spelling and grammer issues. Some members have felt it their responsibility to correct these sorts of things. I feel pity for their overall lack of having a life......0 -
My REM 700 prefers the 150 grain bullets, especially the Sierra SPBT. M daughters M700 prefers the 130gr. as does my son-in-law's Ruger 77. I use the old H4831 because I have a lot of it. On a good day, if I, do my part, the rifle will shoot just a hair over 3/4" for 5 shots. For all intents and purposes you don't give up anything, ballistically speaking, by going to the 150gr. bullet. If you doubt that, run your numbers on a good ballistic program and you will see, within the practical range of the most hunters and the 270 WIN, nothing is really gained or lost between the 130gr. and 150gr. That is a very broad statement that I know will be nit picked to death, but just check it out with a program like Sierrs's Infinity, Oehler's Explorer, etc.
