I picked up a 300 SAUM this fall for a song (model 7 stainless) and decided to get a little more serious about reloading tech. So I picked up a OAL gauge with a 300 SAUM blank and a tarted measuring overall length with specific bullets. Various bullets all seamed to measure out just over the cartridge OAL by 0.03 to 0.02. Then I stuck a 165g Accubond in the blank and pushed it in to the chamber and pushed and pushed and pushed until the bullet met the lands. Its well over 0.1 of an inch longer than the OAL.
The 165g Accubond is nearly 0.25 longer than a Speer 165g Grandslam.
Looking at the Accubond sitting in the blank cartridge it looks like there is only 0.25 to 0.30 of the bullet remaining in the neck. I did not measure it but it appears that the Accubond loaded "just off the lands" will probably not fit in the magazine of the model 7.
My question is what have other users of Accubonds found for how long these bullets are and their subsequent loading with respect to the cartridge OAL?
How far off the lands are you pulling Accubonds back?
