I wanted to see what you guys think about Winchester .40 s&w ammo 180 gr vs 165 gr (white box). I normally use the 180gr in my XD40 tactical , SHIELD .40 and G23.
Haha. I use Critical Defense home defense ammo in my home mags.I was praying you were going to say target practice.
I don't own a .40, but I never really care what grain I'm shooting in target practice/training applications. One might hit a little higher than the other, that's about it.
Ill compare the 180/165 at the range next weekend. Ill report back on it.What Nathan said. I buy whatever is available/ cheaper. I carry 165 so I usually try to practice with 165.
What gun were you using?I've found 165gr to shoot a couple inches higher than 180gr at about 12-13 yards. I didn't really notice any difference in recoil.
That is a big differenceI'm surprised to see posters say they hardly notice the difference in recoil between 180 and 165. It's noticeable in my XD40. Also, when deer hunting, I went from my usual 30-06 180 grains to a 165 grain projectile, and my shoulder is very grateful, especially after range practice. With 180's I could only shoot about a box of 20 before my shoulder had enough, with the 165's I can shoot 3 boxes or more before the shoulder wants to go home.
Thank you for the hard data.Well, there's a difference. You won't typically find a 180 gr. load above 1000 FPS, or sub-sonic. with a load like the Remington 165 gr. Golden Saber that's rated 1150 FPS, Super-sonic, both energy and momentum are higher For instance with velocity more like 975 FPS, a 180 gr. JHP will have 380 Ft/Lbs of KE with a momentum of .779 Lb-seconds. A 165 gr. JHP at 1150 would have an energy of 485 Ft/Lbs with momentum at .843 Lb-seconds. Personally, I don't do sub-sonic in anything until I get up to 200 gr. JHPs in .45 ACP. People get all wrapped up in what 'doc' Roberts opinion is and frankly, I could care less. I test my own and he's a dentist. If you go here: Best Choices for Self Defense Ammo You'll see the bias for sub-sonic 180 gr. JHP loads, but if you read the complete section on .40 S&W you'll find a scant bit of information for a load that passes all of the testing: the 155 gr. Gold Dot at 1200 FPS. That's KE at 496 Ft/Lbs with momentum at .959 Lb-seconds that's about as high as you'll find in a factory load. Some people assume greater momentum and penetration by bullet weight, and that's what it is: ASSUMPTION. With a good performing JHP, the math and physics just don't lie.
I normally buy/shoot 180gr but they were all out. So I picked up a brick of 165gr. Both were the same price.Ive shot both 180 and 165's what ever was available at the time but I did prefer the 165's.. they seemed to have a little better poa/poi.
