[QUOTE="manitou, post: 1485370, member: 105280"] On the base of your case where the writing is... there can be gall marks if your rifle is shooting over pressured, almost like the brass is smeared or gouged. Also can distort the writing. Are your primers overly flattened? Any faint ring around the firing pin indention on your primers? If the rings on the actual bullet are apparent on ALL makes of ammo, I am inclined to agree with the above posters that the bullets are jamming into the lands due to improper chamber cutting/short throat. This can cause exessive... and dangerous pressure spikes. Most bullets do well with .080-.010 jump.into the lands. Some reloaders will load just to touch the lands slightly, but adjust their charges to accomodate the pressure. Not trying to spread doom and gloom, but this could be a hazardous situation if all brands of ammo are exhibiting the marks on the bullet. Regardless, factory ammo is sized very short to accomodate variances in manufacturers chambers to avoid over pressure. If your rifle is binding while working a round in the action, something is definitely not right. [/QUOTE]
