Hey long time reader first time Poster. So go easy please.
Being new to hand loading and firearms having come from anti gun family I have somewhat thrown myself head long into it and seem to have swam out a little past my depth.
After the purchase of my first gun I was drawn to reloading for Economic and entertainment purposes. I have started to reload now to my 10mm. Which As I understand is on the higher side when it comes to pressure?
The problem is I have no one to turn to when it comes to advice or experience in such matters.
Which brings me to my question, is this amount of cratering normal or am I in the Danger Zone ?
(I do not recommend anyone attempt to imitate this and accept no liability if you do and it goes south)
I Do have a chronograph to test velocities.
The following is some more data though not sure if it is helpful.
Gun: Springfield Xdm 5.25 barrel (Stock everything)
Bullet: accura 180 gr copper plated HP (yes their not a cheap as lead But they’re not as expensive as name brand bullets either)
case: mixture mostly S&B and some virgin Star-line mixed in
Primers: CCI and Winchester (side note I attempted to see if there was a difference in velocities based on primer and same charge.... there was none that I could tell)
Breakfast: eggs,toast and 3 cups of coffee
Temp:43 degrees according to my car thermometer
The cases are in order from left to right
1. S&B 180 gr -Control for standard
2. Buffalo board 180 gr- control for p+
3. Longshot- 9 gr
4. Power Pistol- 7.6gr
5. longshot-8.7gr
As you can see the only apparent signs of over pressure are the slight cratering a small ding on the head (think that's the right word) of the 9 gr Longshot brass which must be from the ejector?
This is defiantly not present on the factory rounds.
The 9 gr of long shot is .5 grs below the book max for this round. But my question still stands should am I just being overly cautious or have have I the max charge for my specific gun?
Feel free to ask questions and I'll answer best I can.
Any wisdom is appreciated.
Thanks
