[QUOTE="jc5420, post: 2808623, member: 16425"] Copy and pasted from another discussion. HodgdonExtreme wrote: Thanks for the update, it coincides well with the velocity prediction you get from an energy balance that assumes muzzle energy will be same between both bullets, only the velocity will be different to reach that energy parity. Based on this, I'm unsure what the advantage of these 130s is over the 140s?? It seems to me that Berger was going after a specific audience with these: The autoloader shooters - hence the name "AR Hybrid". The ogive is short and stubby on these. Clearly Berger traded off some BC to facilitate 2.800" COAL with the gasguns, a limitation us boltgun shooters don't share. After this rough test, I completely agree. BUT, I do see an advantage of less recoil and flatter shooting. The down side is you have to run higher pressures to achieve the end goal. 140 Hybrid with 37.4 Varget is my MAX load. I am running 36gr Varget at 2730 (rough numbers here for drop from JBM) 1000y >> 304.3" drop / 63.7 10mph wind drift 130 Hybrid with 37.9 Varget is my MAX load. Running 37.3 Varget at 2850 (rough numbers here for drop from JBM) 1000y >> 286.3" drop / 66.0 10mph wind drift As you can see very similar numbers in performance, only drop shows difference. 140 Hybrid runs 96.25% of MAX load where as to keep the same performance with the 130 Hybrid running 98.4% What I gather from that is a shorter brass life expectancy and possibly barrel? (Though barrel doesn't really matter and not sure how much that would reduce the brass life) Just looking at a cost perspective even though irrelevant you could assume to spend more on powder, less on bullets, more on brass and more on barrels. (More overall cost for minimal performance gains?) All of this is just thinking out loud and none of it really signifies anything. Hell I could be completely wrong in my thinking and turned around logically. [/QUOTE]
