I will not be loading max rounds for this rifle.
In his article Mr. Taffin references H4227 (IMR4227) often for his loads as well as lil'gun. Given his vast experince I'm sure these are good powders for this setup.
Has anyone else used these powders?
Also given the pressures this load can generate should I use a gas check regardless of the vel I plan to use.
Here are some designs for a bullet that I made with the help of Mountain molds software. I want to end up using one bullet and two loads. One with Unique for a "lite" load around 950-1000fps and then a warm load at 1,300-1400fps.
Bullets will be WW and lee lube.
A 500gr GC

A 440gr GC

Anyways this is one of the ideas dancing around in my head. I also plan to loop 4in off the barrel add a past recoil pad and a peep sight.
