My 2 cents worth on your loads for the 270 Win
It sounds like you hit up on a solid winning combination. The 270 Win is a great cartridge and is very popular because it works. The 130gr load is one of the most popular along with the 140gr for Deer. Most posts I have read said if they get good groups with the 130gr on the 270 they don't even look at the 140gr. The 130gr should shoot flatter than the 140gr due to it flying faster. But at the range you are shooting ~100yards it doesn't matter. The Remington corelocks are a solid bullet, they are not considered a Premium bullet but the Deer won't know the difference at 100yards. The really nice things about the Remingtons is your rifle likes them and these along with Federals are what usually go on sale at the big chain Department stores Wallmart, K-Mart, Target, etc. Don't worry about your choice, go buy 3 boxes of them at the store on sale. Then head to the range for some practice with two of the boxes, save the third for hunting. If you open the flap of the ammo at the store you will see the lot number. I recommend that you try to grab the same lot number when you buy ammo if possible. It just means they were made on the same day, on the same machine.
