IMR 4831 and new bullets

[JohnyRingo]

Here are some measurements I just gathered:

COAL distance to lands = 3.653"
My current COAL with Accubonds = 3.64"
Current jump = 0.013"

Because of feeding issues, I want to adjust COAL to 3.63", which means a 0.023" jump.

Height of 67.5 grains of powder in case = 2.107"
COAL with Accubonds resting on powder = 3.487" (no compaction).
COAL with LRX 175's resting on powder = 3.579" (no compaction).
COAL with TTSX 180's resting on powder = 3.595" (no compaction).
COAL with Hammer Hunter 181's resting on powder = 3.644" (slight compaction).

It doesn't look like I will have any issues with trying out the LRX's and Hammer Hunters. I do plan on using a drop tube and dropping the powder charge to work up a new load.

There are other powders that may help accomplish your goals also. Possibly h4350 or imr 4350 could get you out of having a compressed load and run shorter oal..actually there are all kinds of scenarios available to you. Especially if you have components and dont mind reworking your load. Es of 26 is ok but you can do better.
