Does anyone have suggestions for a bullet; and powder combination for the 140 or 150 vld's. I'm working up a long range load with a 500-600 yard maximum in mind. Or, should I just stick with my 140 accubonds and SST's? I'm getting 3097 fps with my AB load and I'm wondering if I can expect the 140 grain vld to equal or exceed that velocity.
I recently " took up" the 270' in part due to a gun trade. Well the particular270 that I have is a Browning A- Bolt, with Boss. Long story short, that means that my actual barrel length is about 19.5, for a overall 22 in barrel. That all being said, in order for me to get respectable speed with 130-140 bullets, I had to go to a faster powder. Under good advice from another 270 fan here, I tried 4064. Also I use IMR 4831.
The last time I shot it, I was able to get 3000+ with 130's and just over the same with
140 Berger VLD. I have not tried 150's yet, but will probably stay with the 140 bullet. I am sure it will shoot them, but because of barrel length, will not be able to get desired speed. So, depending on your barrel length, give 4064 a try. It is often over looked, and is a great powder. Low ES, SD also.
P/S, your speed should be about the same if you go to the VLD as AB.
