When shooting factory (or loaded full power) 357 Magnum and 9mm, any big difference in point of impact on 25 yards?
Hello, I finally made it to the range earlier today. It's been hot here in Texas and my range is outdoors. Anyway, I took my Blackhawk convertible and a box each of 357 and 9mm. I shot offhand standing, then tried with sandbags, and then shot at some steel plates, all 25 yards.
To answer your question: At 25 yards, I did not see any major difference in point of impact between 357 and the 9mm.
I do reload, but the 357's were pretty close to factory (158 grain with 2400 powder.) Usually I load lighter, but these were fairly stout. My 9mm load was 115 grain bullets with HS-6 powder. A very good load I'm using in my other 9mm's also.
I really felt like the 9mm was much better in terms of accuracy. From a sandbag, I was shooting really good groups. For me anyway, I'm not the best shot, so I'm not going to tell you how many inches. But I was impressed anyway. I was shooting low today, but all the groups were consistent, i.e. both 357 and 9mm were equally low. That was me, not the bullet or the gun.
My Blackhawk has a steel grip frame, so the recoil was obviously more mild in the 9mm, but with the 357, it was very pleasant as well. I think I shoot more 357 and 38's in this gun than 9mm, only because I have other guns strictly for 9mm.
hope this helps...
