Maybe we need a sticky for this as it seems to come up regularly sending other threads off course? I am currently working up some loads in .270win for 130 & 150gn Nosler ballistic tips. I am trying to get exactly the same ballistic performance with the 2 different rounds out to 200mtrs. A rifle is a beautiful Mannlicher designed light for the alps with a 20 inch barrel, happily 3 shot grouping sub MOA with factory ammo which I hope to also improve on. Loads I have settled on are: Norma brass, Fed 210, 130gn Nosler, 56gn Vectan T8000 (=H4831) Norma brass, Fed 210, 150gn Nosler, 54gn Vectan T8000 (=H4831) Both give a 10-11cm drop at 200 when zeroed at 100 (tbc on the range) Both these loads run a chamber pressure of just over 52,000 psi - but both fall well short of factory loadings and factory velocities (even when I calculate for a 25/26 inch barrel). I will measure them on the crono next week and comparing to the Norma factory loading. .270win advantages are in its flat trajectory (great in the mountains) which depends on high velocity, 3000fps +, I am 200fps short of that. How close to factory loadings do others load to in these sort of calibres?
