[QUOTE="boomtube, post: 503403, member: 9215"] Your group changes following charge changes are typical, that's why we must experiment to find the best shooting charge. You may be expecting too much. Win 94s typically shoot 3 MOA groups no matter the load, while a really good Marlin 336 might shot 1.5 MOA groups. Bad load choices will make that worse. You tell us what powder and bullets you are using but not what rifle; that matters! Marlins do tend to be a bit more accurate than Winchesters but consistant 1" groups are virtually impossible with either. Shakey benches and rests, wind, poor triggers, inexpensive scopes in "see-through" mounts and unskilled shooters combine to make it quite difficult to obtain high accuracy! Occasional small groups of a few rounds are statistical anomolies with no value. All that really matters are groups with a lot of holes, say twenty or more, only that will actually let us know what our rig is capabile of. For instance, say your rig and load is a 4" shooter. You fire and put three rounds into an inch cluster high and right and later put three more low and left but the outside shots are within 4"; you really don't have two tight groups with two POI, you have six shots inside the expected range.
