The range was 338m and you can see the bullet speed, energy and dials in the table below which comes from my ballistics solver.
I used 1.2 MRAD elevation but held not dialled and applied zero windage. The slope angle was -19° but not really a factor at this close range.
The rifle is a Tikka CTR in .243 mounted (bedded) in a custom made carbon fibre stock. Scope is Kahles 624i 6-24x50 with the SKMR3 reticle. I use a custom-developed load that I worked up myself and make myself. 87gr V-Max pill pushing 2913fps at the muzzle.
Pretty routine for a man of your capabilities but I am impressed 😎
Great answer, too. Much detail 👍
I expected maybe a 30 cal, but the more I read and study the .243 I am finding that it is excellent for medium sized game like deer (and Roos!)
When culling roos I have to head-shoot them. The .242 imparts enough energy and gets there quickly, a (relatively) flat trajectory, so works nicely. I prefer my 6.5mm Creedmoor but it's too much for the job. Also my .308...Just too much.
I shoot my .243 out to past 1000m, but would not cull at that range. I shot a goat out there though, centre mass. My 65CM...Well past 1600m. I love that rifle system.
