i installed a SWFA SS 10X and with the for end stable and solid it was ready for the range.
i worked up 5 different loads in .5 grain increments with the highest being 42.0 grains. That was the highest suggested charge weight from the hodgdon website for the 100 grain bullets (Speer 100 gr. BTSP)
I decided i would do my development at 200 yards this time. I had shot the rifle with Hornady american whitetail 100 gr. interlock BTSP (the cheapest hornady factory load) and it was shooting sub MOA at 100 yards and felt i would get more info from a longer range. as well as a bench mark to meet or beat.
i actually experience some high pressure signs with my lightest loading of 40.0 gr. of H4831. i had flatend primers but that went away with the next loading. i had a feeling this might happen because the powder is a relatively slow burner and i have a 26" barrel.
anyways 42.0 grains was the winner of the accuracy race on this outing
5 shot group at 200 yards
as you can see i did have a flyer but that was all me.
i might be able to get it even tighter after using the fire formed brass and neck sizing. also i still have room to play with my over all length.
