I have not been able to find any load data for 155 grain coated semi wad cutters. The projectiles came from Summers Enterprises. Looking for 231 and blue dot load data if anyone has anything it would be greatly appreciated.

Most just use data for the cast bullets of the same weights for the coated bullet types...
Here is some Lyman cast bullet data that should help... I do like Blue Dot powder

You will likely want the crimp slightly below the SWC cut on the straight portion of the bullet body.

Thanks. I imagine I should be able to load really close to the 150 projectile then? Likely around 10.8 max for the 155?

Yes so long as the bullets make a good seal you should be just fine! You might even be good to the 11.0 grains, but you may fine better accuracy at slightly lower charge weights!

Thanks. I'll load some up at ~10.7-10.8 grains and go from there.

Finally got back to the range with my new chrono. Running about 1241-1332. Question is where should 155 grain coated lswc be running?

Having an issue with the Sig tacops extracting.
