I am way, way late providing any updates. While I can load and shoot this bullet in 10mm everything about it is suboptimal. When I load it to my usual COL of 1.26 the bullet ogive is below the case mouth. In this situation you are bound to get dirt, lint, whatever gathering in that gap. And accuracy for me was meh. Most importantly it leaves a lot of bullet stuffed into the case increasing pressure. I didn't load anywhere near max but this load was really snappy while providing relatively low velocity. Loading them long, just under 1.27 COL, they don't feed 100%. But they did shoot fairly accurately and gave expected velocity. I ended up buying some Acme 180gr FP's and am not looking back. It is a relatively short bullet that is similar in dimension to 180gr XTP's. They are shooting great and giving me the velocity I want without any signs of excess pressure.

Thank you both for your replies to this! HesedTech you have definitely called it on the problem, this bullet just isn't right for 10mm. Funny enough I now notice that my favorite bullet producer (ACME) redesigned their 180gr flat point. The original bullet is shaped just like these DG's and newer design looks to be shorter and fatter up top. I just wish that they had these in stock. I used to have a number of 40sw's but went through a caliber consolidation when I stocked up on reloading supplies. As I don't have any 40sw brass or loaded ammo I am going to skip buying a new gun in this caliber, but I like where your head is at. Hopefully these 10mm rounds will shoot decent as I have quite a few of them to blast through. Noylj - I have already done most of what you instructed. Unfortunately I found that magazine length limits me to around 1.27 COL. This bullet will plunk in the chamber well beyond 1.40. I do really appreciate your numbered guide on reading the scratches as this step is relatively new to me. In this case, the rounds chamber pretty smoothly but I do see some occasional scratches around the case lip so I am going to give them a smidge more taper crimp. I am still wondering if there are any possible problems I will run into having the ogive seated below the case mouth. I think it is going to be fine and am guessing the potential issues are just accuracy or leading (If I over crimp). I am hoping to get out and shoot a few of these today so will know soon.

Here is a pic of the finished rounds.

Hello, I just received my first order of DG Bullets 180gr and am experiencing an issue that I cannot find much info about. I am loading 10mm using starline brass and find that even when the bullet is seated to maximum COL of 1.26" the ogive of the bullet is slightly below the case mouth. With other 180gr bullets I usually have a little shoulder above the case mouth. I have attached a picture of the bullet in question next to a Lasercast 180gr and you can see how the shape of the DG bullet differs. I would like to know if anyone thinks this will be a problem? After crimping just enough to remove the bell, the finished cartridges look pretty good and hand cycle fine. I am thinking that the only issue will be a slightly longer jump to the rifling. I only have one 10mm, a Glock 20, and it looks like I can load to a slightly longer than spec COL of 1.27 and the rounds still fit in the magazine. The ogive is still below the case mouth but getting close at this length. I have 700 of these bullets and hope they will shoot just fine. I have already loaded, and shot, some 9mm DG bullets that shot great without any leading. Appreciate your thoughts.
