need a long range 243 bullet

[Freebore]

I agree with Cal on that 70 gr Nosler Bal Tip for varmit. I use the 95 Nosler Bal Tip (almost identical to the SST) for deer over N160. VV powder gave me the best accuracy and velocity which I use exclusively in my Swift for varmit.
I had used the 85 gr. Sierra game king on deer over IMR4350 with good results and accuracy. I went to the bit slower but heavier bullet for retained energy/velocity.
All the above gave less than .5 MOA at 100 in a Sako
The 243 is a great cartridge to reload for! You do need the slower powders for the heavy bullets to get the performance.
