Nooooooooo.............. not yet. Still don't know if I trust myself to pour liquid metal down the chamber. I had a look at a couple youtube clips, but ahhhhhhh. Not confident yet.
I did, however, attempt to make some crude measurement based up component lengths and displacement of those components ............ I know what I'm talking about.
So the following is only hypothetical information based upon my particular measurements taken this evening:
Bertram Brass case - 1.069" case length
Hawkesbury River 122gr projectile - 0.704"
I can put the projectile and case into the chamber, and still have space before the projectile touches the lands - 0.06" space
Not knowing exactly at what point on the ogive the lands make contact, theoretically, I could load a round for this rifle slightly less than 1.833" COL.
Does that sound right for a .310 cadet? To have a chamber length that long?
So now taking the two of my first attempts at reloading for this rifle, as pictured above, the COL for these are:
HR copper coloured 122gr - COL 1.554"
HR black coloured 128gr - COL 1.570"
That's an average bullet jump to the lands of 0.270". Does that sound sort of average? Its way more than what I load for in my .308 or .223. I mean, its not a revolver!!
Does anyone think that this is out of the ordinary and maybe the chamber has been reamed out a bit?
I have a batch of newly loaded rounds for Sunday, trying to at least see if I can get some consistency. Just need to take me out of the equation I suppose
I know, Stoney is just going to tell me to cast the chamber and stop asking questions. I know Stoney, I'm just warming up to it. See how I go this weekend first though.
I really appreciate any info and help you folks provide too, its very much welcomed.
