a few things, most guns are pretty picky with ammo. my rem 700 22-250 hates winchester ammo but likes cheap rem umc loads. You kinda have to try them all. this poses the issue that the most accurate round may not also have the ballistics you're looking for. the 270 is a very good caliber and a very popular one with a huge variety of factory loads availiabe, so eventually, you'll probably find a tight pattern with the ballistics you're looking for. you will notice a big difference if you get a gunsmith to lower your trigger pull from factory (5+ pounds) to about 3 lbs. a trigger job is usually about $50 and well worth it. be sure to use your safty though because the gun can go off easier if you drop it with a 3 lb trigger pull. you want to make sure you clean the barrel from the breech before you shoot it, they put grease in the barrels so they don't rust during shipping. if you didn't clean it, it's probably not damaged, just gunked up. use remington bore cleaner on a nylon brush followed by rem oil on patches. it's a good idea to clean it after shooting it each time or between 20 or so rounds. check the crown for damage, if the end of the barrel isn't symmetrical, the bullet won't leave evenly. if it's damaged, take to a gunsmith, they can fix this. Also the barrel can warp if you wait a few minutes between shots. Best is to shoot 3 fairly quickly or wait 8 or so mins between shots. remember, if you're deer hunting, you'll be making a cold bore shot anyway. finally, and this is a big one.. you might want to replace your scope. a 270 has quite a bit of recoil and one reason leopold, burris, and nikon scopes cost more is because they can handle higher recoils. bushnell makes pretty clear glass, but sometimes they move after shots on bigger calibers like 270's. you can get a decent scope after deer season on sale for about $150. i've found that most grouping issues can be solved with the above info. i would also take it to a gunsmith and have them check it out. get them to shoot it if you can. most fixes aren't as expensive as you would think and estimates are free. hope this helps, happy shooting!

elaskowski is correct about trigger jobs and cleaning. My favorite caliber for deer is .270 and I've had several over the years. Most shoot pretty good with everything, but once in a while you'll find one that's picky about ammo. If you know someone else who has a 270, asked them if you can buy about 5 rounds of their ammo and shoot some 5-shot groups. Try several types and weights in your gun. This method is much cheaper than buying full 20 round boxes at a store. Try 130, 140 and 150 grain weights. On picky guns, you will often see a marked improvement with one weight over another. These three suggestions (trigger lightening, cleaning and ammo type) should tell you something informative about your particular gun! Good luck!

I would say that covering your 50 yard group with a silver dollar is not very good performance and you need to find out what is going on with it. Take some targets to your gunsmith and have a conversation with him about the gun. The 700 is so popular even the most rural of gunsmiths has experience with them. Some things to look for are the mounts and rings must be tight. And should be locktighted to preven loosening. Check and make sure the stock screws are tight but not overly so. Somewhere in the 25-35 inch pound range should be about right. Clean the bore thoroughly and shoot it some more. It may just need to break in. I had a .243 that shot well initially, but after about 100 rounds, it would shoot one hole groups at 100 yards. During the break in, I'd clean it several times. However, I have never used a "clean after every shot" regimen and my rifles shoot acceptably for me. Pull the bolt out and look to see if the bluing wear on the locking lugs is wearing evenly. If not the action may need some work. If this is a new gun, Remington service should be able to fix anything that is wrong with it. You may have to be polite and persistent, but if you stay after them they will take care of you. Regarding the factory trigger. I don't know if you have the new model trigger or not, but even the old model trigger can be adjusted to be safe, reliable pull, but it has to be always respected and never take the safety off unless the rifle is pointed in a safe direction. The trigger situation generally happens when the shooter pulls the trigger with the safety on. If the sear engagement has been adjusted too shallow the sear notch on the trigger could move enough to allow the sear to drop when the safety is moved to the fire position. I hope you can get it sorted out.
