Still a bit short on information. Bullet size is important because if undersized, you will get leading in short order. Sometimes, seating the bullet too far off the lands will also result in hot gas etching the sides of the bullet and depositing the lead on the barrel ahead of the bullet. Sometimes the source of the data can be helpful. If just looking at data and taking a guess, will also be a problem. Since there is no bullet weight or mold number given, one can only guess at the pressures involved.
