1)You don't actually have to have the extended front baffle, you could work with the standard and get the extended model if you just need it.
2)You can single round load with the magazine in place(setting the round on top of the mag lips) or you can use something like the Fred Sled. You would need a single shot loading ramp if you did something without a magazine. Sharp Shooter Supply has what you need. The 223 mag is a close fit. check it out
