I recently bought some 9mm 120gr TCG hi-tek coated bullets off of bayou bullets and I am having some trouble finding a recipe for them with CFE pistol as the powder. I am using hodgdons CFE pistol in a canik tp9sfx with a 5.2 inch barrel with range brass and CCI primers.
I started off using the loads from hodgdons website and the recipe for a 115g LRN worked great. So for my 120gr TC I was going to use the recipe -15% for the 125gr LCN and work my way up until it functioned properly or started showing any signs of over pressure. when I created this round the recipe had the COL at 1.125 which as I figured out doesn't properly headspace in my gun. so I did some research and found out the some guns have their own max COL for a particular bullet to headspace properly. I did the "push test" with this bullet and the max COL for this bullet in my barrel is 1.087 then -15 thou so I would have to seat this bullet at 1.070.
now the recipe for the 125gr LCN is completely out of the question with a COL difference of .055. then I started looking for a similar weighted bullet with a similar length to keep the inner case space equal. the length of the 120gr TC is .533. I found this website for lengths of bullets. the only other data hodgdons lists in this weight range is for a berrys 124gr HBRN, but the hollow base screws with keeping the inner case space equal, a 125gr hornady HAP, and a 125gr sierra FMJ which are both jacketed so their recipes are useless. there are so many variables to each recipe that ive given up on that idea completely and its probably too dangerous to try and fudge a recipe to work for me anyways. im now learning that I probably should of done some research on a more common pistol powder
so my question is now on you guys, do you have or have you found a recipe using a lead 120gr TN bullet seated around 1.070 with CFE pistol powder.
also if I cant find anything I assume my best course of action would be to buy a crono and work up a load starting with like 2gr of powder until it reaches a velocity that reliably functions my gun with no adverse pressure signs.
Im new at this reloading thing so if im just spouting a bunch of nonsense let me know, any advise is appreciated
thanks
