Tikka Ace Target in 223 Reloading

[Freddie 121]

Not sure if this has been asked before ..Anyway just took possession of a Tikka Ace Target in 223cal I have measured the C O L at 2.382 inch 60.5mm I have loaded
5 rounds of Vit N140 @ 24.5gr and a C O L of 59.6mm 2.350 inch my question is should I get closer to the lands or am I in or around the ball park both with length and charge
I load pistol rounds .45 and 9mm but rifle rounds are a whole different ball game any info would be gratefully appreciated

Thankyou

Freddie

Will they fit in your magazine at that.
I load 55gn vmax at 2250.

 

[Freddie 121]

Yea they fit ok bolt closes and ejects dummy round at the same spec as loaded rounds ie:- same length

the 77gr smk will shoot just as well at 2260" with out chasing the rifling.
