It really depends on the gun in my opinion. Some of my rifles have poor irons sights so a low powered scope proves faster for me. Scopes arent necessarily about shooting long range.
Another benefit to a scope is that at low light situations they will improve your accuracy by gathering available light and brightening your sight picture (over irons).

Smoothness of the rifling as it is being cut or impressed makes a big difference in the velocities you get from your rifles .
As Rick and Jaycee mentioned, it's not only about one single thing such as powder or barrel length. Our 1st TacOps Tango 51 shot the same velocity at 20 inches as compared to a 26" did with Fed Match 168 BTHP and the difference between the two(20" and 18") was only about 30 fps with that same ammo. The shorter barrels where much better all the way around and with no penalty in accuracy.
Decide on caliber with regards to game hunted and your recoil sensitivity, then simply get what configuration fits you physically.
Not mine, it went back to the original owner. Ammunition was illegal,Quote:

On a scale of burning rates # 1 to # 144 , 4320 is listed as # 100, as for magnums there are much slower burning powders that are better suited , meaning more load density giving better accuracy.Quote:

Going one grain over book , you are risking damage to your fire arm and possibly yourself by exceeding safe pressure limits, as the max. loads listed are that , MAXIMUM LOADS tested to safe pressures .
Very curious as to why .416 Taylor ammunition would be "illegal ", when all it is ,just a wildcat caliber ,a .458 Win Mag. case necked down to accept a .416 dia. bullet, it was created by Robert Chatfield-Taylor in the early 1970s.Quote:

Googled it and I couldn't find ANY THING saying its illegal... Also its not on the RCMP website of prohibited calibers.. Think its more "smoke blowing"......Quote:
