[QUOTE="RT2506, post: 2107975, member: 10178"] I don't have a 6x45 but I do have some experience with 6mm bullets running 2800 fps. In an estate sale I got a T/C Contender pistol frame with a few barrels. One of the barrels was a custom made (maker unknown) 14" in 6mm/225 Win. It uses the old rimmed 225 Winchester case necked up to 6mm with a blown out AI style shoulder. My trouble was it has a 1 N 14" twist. I wanted to use this barrel for deer hunting and the first bullet I wanted to try was the 80 gr Sierra Single Shot Pistol bullet that is now discontinued. I did get loading dies and some cases with the barrel but no load data. I treated it like a wildcat of which I had worked with few in the past. Closest case capacity rounds were the 6mm PPC and BR. I came up with Varget as the powder which ran the 80 gr Sierra SSP 2800 fps with better than I could hold accuracy. Way under MOA. Most of my shots would be between 50 and 110 yards from a shooting house over a corn pile. Found out that the 80 Sierra SSP would not exit on broadside shots through the ribs and deer would run off a ways into a very thick pine, green briar and swampy cut over and leave little to NO blood trail and was very difficult to recover. The next year I tried to get the Sierra 85 gr BTHP to shoot and it would not stabilize in the 14" twist. I also had some 85gr Speer bullets but figured they would not stabilize either because they were about the same length etc. as the Sierra. Speer did not make the 80 gr bullet at that time as far as I know. No other lighter bullets I had access to I thought would be suitable from prior experience of shooting varmints with a 243 Win rifle at the impact velocity I was going to get with my 6mm-225. I just used the 80 Sierra SSP bullet and picked my shots. I waited until the deer was facing me and put it's head down and I would shoot in the neck where the neck met the body. Bang Flop. I really think the 80 gr SSP is the same as todays Sierra 80 gr varmint bullet. The next year I was told by a very experienced 6mm PPC shooter with 14" twist that the 85 gr Nosler Partition would stabilize at my velocity and was an excellent deer bullet that most often would exit even through the shoulders. I did purchase some of the 85 Nosler Partitions but never loaded any because I already had decided to have MGM make me a 14" 30-30AI barrel. 125 Nosler BT at 2670 fps SMOKES deer and the rest is history as to deer hunting with the 6mm-225. I have relegated it to varmints and bought up a supply of the Sierra 80 gr SSP when I heard they were being discontinued. I wish back then I could have gotten some of those 80 gr Speer bullets because the sound like they would have been a perfect bullet for me. [/QUOTE]
