32-20 loads in 1400-1500 fps range for hard cast with gas check?

[The Kurgan]

Any medium power 32-20 load suggestions?

I currently have a bunch of .314" 110 grain cast lead bullets with gas check courtesy of jethunter.

My rifle is a BSA Martini Australian Cadet with a factory 25" barrel with a very good bore.

I have an assortment of 32-20 brass, with a preference for Starline brand.

My powder on hand is IMR 4227. I also like Trail Boss for light loads.

I only have small pistol primers on hand, but I will buy some small rifle primers.

I made a load to test, and curious how it will perform:

Starline 32-20 brass
Winchester small pistol primers (not enough ignition?)
12 grains of IMR 4227
deep seated 110 grain cast lead bullets with gas check
very light crimp
... bullets seated just enough to touch or ever so lightly compress the powder.

My research tells me this should produce low 1400's to 1500 fps.
(not sure about pressure)

First, I think that pistol primers will do just fine.
You probably have a pretty good load made up. I checked with the Lyman cast bullet book and with 110 bullet, either flat base or gas check, they show from 9 to 11 grains of 2400, which is not that much different than 4227.
They show 11 grains of 2400 as approaching 1650-1700, with 9 grains near 1300.

I'll shoot them while on holidays and report back.
