220 vs 240 Sierra Match Kings

[N310toN170]

I've found that the heavier rounds cycle more consistently (inertia), and a greater bearing surface (accuracy) and occupy more case capacity (safety).

That being said... the price point of the 220 as compared to the 240 makes it hard to justify the 20gn's unless there's a very specific reason.

I prefer the 220's myself.

It appears you are correct sir. My apologies...

No apology necessary. If you are loading conventionally your statement would be correct as the larger bullet eats up case capacity. If you were loading the 240SMK to max load and the 208 A-Max to max load the A-Max would use more powder. The difference is that the two wouldn't be going the same velocity. The speed limit on subs is what makes it different.

As I have noted previously, I have not ever had anything get up after being hit by a 240 and tell me it didn't do the job in a terminal fashion.
