Speaking of the Win 70. My main gun for decades is my grandad's Win 70 Feather in 30-06. Through the years I shot mostly (and only) the 165 grain bullet thru it, and mostly for deer. In 2004 I filmed an outfitted hunt of my dad's. He was using a similar weight 30-06 but was shooting the 180 grain. The 180 grain had fantastic effect on his Rocky Mountain Bighorn, and a 5x5 Rocky Elk. I snuck out camp with it one day and got into a situation where I could only afford an instantly lethal shot on a mule deer, and so when the time came - his 180 gr slug did it perfectly. Since then I have switched over to the 180 grain (re-zeroed) and have enjoyed nice lethality in it with my win 70.
Question: I was checking zero this afternoon. With 180 grain slugs I was 1-1/2 inches high at 50, right where I want to be. I decided to crank thru some 55 gr accelerators and 125 grain `low recoil' rounds. They all came in at ZERO at 50.
SO, THE QUESTION: AM I GETTING MUZZLE RISE WITH THE HEAVIER BULLET?
