Scrollcutter505 Gibbs starting loads......dies are on the way!
Can anybody give me a starting load for 505 Gibbs? I would like to use IMR-4350 in front of the Federal 215 primer. The bullet will be a 525 Woodleigh soft.
Jim Wisner didn't have access to his reloading notes when I talked with him, but thought that 100 grains would be about right with 140 giving close to factory ammo velocity. I'm not interested in going over factory loadings.

H&H_MadScrollcutter,
The AEM Accuload program I use lists the following load for a 525 Woodleigh in the 505 Gibbs.
IMR - 4350 - starting load 94.5 grains for 2140 fps and 33400 psi.
Max load - 104.9 grains of IMR - 4350 for 2250 fps and 39100 psi.
(Above loads calculated for a 24" barrel.)
The A-square manual lists H- 4831, only 1 load, 132 grains of it for 2257 fps and 34 500 psi.
It also lists IMR 7828 and RL-22 if you are interested.
Hope this helps you out a little, good luck with your 505.
H&H Mad.

Contact Geoff McDonald at Woodleigh. He has always been very quick and helpful giving me load suggestions.
