So I have been looking at purchasing a higher end 17 hmr. I was going to build a CZ 17 HMR and started looking at a lot of things.
I noticed that the all the higher end guns had 22-24 inch barrels. Anschutz and Sako . So I thought that is what I wanted to do.
I looked up the optimum barrel length and came across Bullberry arms test that was completed. From looking at the test there was only a 16 foot difference in speed between 21,22,18 inch barrels. 21 was the fastest and the 22 and 18 where with in one feet per second of each other. There was a huge difference in spread though. The longer barrels had a SD of over 80 FPS and the 18 inch Barrel had one in the 40's. From this research I would say that the 18 inch is the optimum barrel. I did not come across any other information in reference to this testing.
My question is this. Why would the higher end performing guns put this round in a longer barrel. I know that their a lot smarter than me, so what am I missing.
Thanks for any help I am about a week out from purchasing a higher end 17 and trying to figure out exactly what I want.
