Here is a group with the 225gr Beartooth.Of course I adjusted the sights...........
VERY nice!!! Congrats!!
Thanks. It couldn't have turned out better. It did surprise me that it met their accuracy claims. The 265gr are not that good yet but close. reflex264
Great! I've got some aluminum gas checks in .452 dia. from James Sage at Sage Outdoors. I have some of my LEE 230gr. TC cast loads put together in .460 with these gas checks on them and will be trying them out soon.
They should do well. I also got some in .40 cal. for my 10mm loads.
I'm trying conserve my XTP bullets as much as I can during these insane times of runs on anything with ammo or components.
I am going to cast some more of the 255gr Lee RFP and size them to .451". It will be a couple of months but when I do I will post the Rowland results with them. reflex264
My test experience with Hornady 225grainers don't test very well as far as expansion. Look at my photos of spent bullets in my Grizzly WinMag. http://grizzlywinmag.com/ ...
For you reloaders of the Rowland take a look at my Grizzly WinMag page and the bullets I test with it. http://grizzlywinmag.com/
The Rowland will be fairly close to velocity and will give you an idea of what bullets will work best in the Rowland.
Thanks Mag Ten. Great pics and info. Do you have any accuracy stand outs? What velocity did you get with the bushmaster 250gr? Thanks. reflex264
Best I can remember about 1350fps. It's mushroom was much better than the 225gr.. I could never get the 225 grainer to open up.
Shot it yesterday at 25 yards offhand. 4 shots, 3 touching and 1 flyer made it 1.25" with the Beartooth 265gr..... I like it!

Thanks for the update Reflex, Do you have some details on that load. I had my Rowland conversion out to the range yesterday. I have been trying Dardas cast .452 255 gr. SWC's, I run them over CCI's, and 13.0 gr of AA #7. seated at 1.235", They chrono 1140 fps. I had some loaded up a little warmer but the accuracy wasn't there. Even with a double sprung mag there was a tendency for the cartridges to nosedive and bump the front of the magazine with the step in the SWC and it finally broke the steel reinforcement out of the mag. My thought it that under all that recoil there is too much mass(full mag, bunch of 255 grain bullets lots of recoil) moving around (Down) for the mag spring to over come. The 13 gr loads seemed to be right at the edge of everything working trouble free..
Here are loaded rounds I am testing. More to come........
Just chronied the new 460 Rowland loads.
All of these are still off of max.
The 265grs went 1108 with a ES of 9fps.
The 200XTP went 1434 with a ES of 6fps.
The 250XTP went 1138 with a ES of 4fps.
The 185TAC went 1128 with a ES of 2fps.
Now to bump up the 265grs.
Got my email confirmation last week after 3 month order backorder. Should see my conversion in 3-5 weeks.
Thanks for all the information guys I am doing one on a g30
Nice MagTen, I'm thinking of going with the ported barrel instead of the comp when I build one.
Someone was kind enough to let me know about this. Perhaps you should know it too:
Roger- you can shoot regular dimension .45 in a Roland barrel; doesn't mean you should. The ACP and Super case are shorter which means they won't headspace on the case mouth in a Rowland barrel but rather relies on the extractor to maintain headspace. Reliability can suffer and more importantly bullet jump can cause excessive leading which can elevate pressures which can cause kaboom. If you are going to shoot the shorter cases in your Rowland barrel I highly recommend you keep it to ACP pressure levels with jacket bullets. Lead hard cast at Super levels could cause problems. It's probably not as risky as shooting .40 in a 10mm barrel (much higher pressure round with worse setback problems) but it's still not ideal.
The G30 looks so sweet. This is mine.
I have two of them and have LW 45acp and 460row. for them,
still need to get a 22# rsa to shoot the best loads.
