Hello In my previous thread I asked for some help related to 215 Hybrids in 308 rifle. I couldn't get it to shoot consistently, you guys suggested bunch of things to try. I tried them all/most and nothing seemed to help. Finally I broke down and ordered Quickload. After playing with it for few hours it looks like I'm not even close to node/barrel time based on calculations. It is only software and can't predict everything but it can't be that far off. For example, I found optimal barrel time/node for 30" barrel are at 1.520ms or 1.345ms(achievable in 308). I read as many threads as I could find online(how much can I trust internet?) and people seem to have success with this combo around 2500ish fps or 2630ish fps. I was getting decent results around 2495fps which is close to most others and barrel time(according to quickload) is around 1.47ms so technically not in node. Other velocity folks are having luck with is 2630, barrel time of 1.362ms which is getting close to node, maybe software is off by a little, so possibly good node right? But catch is predicted pressure is 69090 psi . If we were to assume Quickload is correct(spot on), lower node velocity will be around 2430 fps(disappointing), give or take depending on powder used. Higher node velocity will be around 2707 with pressures of whooping 76000+ psi, only two powders that can be made to fit in this case will be RL 17 or IMR 4007ssc. Powder burn rate etc can have some effect but it can't be that far off? So questions that are driving me nuts are Are most of the claims on internet wrong, about 2500 or 2630 fps nodes? If those velocities are working for some, are they running out of node and having success? Is there a way to tune rifles when load is not spot on in node? last but not least, most if not all are running overpressure or is Quickload built lawyer safe? Thanks in advance Av BTW I'm new to quickload so maybe I'm screwing up data entry, so I'll add my inputs here if somebody wants to double check numbers Barrel length 30 " Bullet length 1.572" Seating depth 3.050" H2O capacity 56ish grains average(fired cases) Powders I have on hand, H4350, IMR 4007ssc, H4895, Varget, Rl 17. I prefer to use H4350 or IMR 4007SSC or H4895.
