[QUOTE="James Jones, post: 180968, member: 8843"] Alot of it depends on the case size , for instance , a full grain differance in a 6mmPPC will have a big differance , it could cause to the gun to group well or bad , it may group .5" with one weight and you increase by one grain and it may group.5" with that but it may gorup .2" with one grain les or more , so the samller cases are going to be affected mor so , with cases of the 308 size and smaller I would up in .2 grain incriments. If you more one grain up or down in a 30-378Wby the differance will likely be very little. BUT , once your pressure are high the small differances in powder can make huge differances so be mindfull of that. Genberaly speeking guys that work up in .5grain steps will find a happy load for their gun [/QUOTE]
