Thread: .270 win load development - Which charge weight do you think?

Greetings,
Looking through the data a couple of questions present themselves.
1. I don't see any groups mentioned so were these actually recorded and if so what were they? Their position on the target ie the vertical distance between group centres would be of interest.
2. The .270W was built on 130 grain projectiles at around 3,000 fps so why are we even bothering with loads that produce around 2,800? A couple of shots at the start load would have validated the data you are working from.
3. Was the barrel cleaned an a fouling shot fired during the shooting? After a number of low pressure shots the barrel was getting quite grubby by the time you got to the business end of the string.
Other than one shot the results for the results for 55.5 and 56 grains look pretty good so I would concentrate my testing and development there. I would also test groups at 200 metres or yards as there will be some parallax in your scope at 100.
