I shoot 3 different 1/48's and I get great accuracy with both sabots and conicals. The problem is I get the best accuracy with a 300 grain projectile and sabot and a heavy long conical - 460 grain Bull Shop. Both of these bullets are against the math in a 1/48 twist - well screw the math they work. I am shooting 3" with open sights @ 100 yards without a real problem... (this off a rest). One of my favorit activities is to set up clay pigeons from 50 to 125 yards and shoot them (I like instant gratification) seeing the birds break. And normally it is one shot one bird.
Here is a target fired withmy stock Renegade... shooting 400 grain Bull Shops - the 460's actually do a little better... And this target would have been better but I was shooting through a chrono and using different powder loads...
Here is another target shot with sabots from a 1/48 - 54 cal Renegade...
This is another target shot with 460's but again shooting through the chrono and using different loads... shooting through the chrono for me takes some concentration away from the target and more to "do not shoot the chrono" The 3 shots in the upper right were at the the 2" bull in the upper right...
Cayuagd, has said it for years.. never under estimate the capabilities of the 1/48...
And to be honest most people will tell you that you need to shoot short projectiles in a 1/48 - but when I try I do not get the consistentcy from them that I do from these longer projectiles... And of course the disclaimer - all guns are different you can only try...
