Using Lead and Jacketed Bullets

This question has probably been asked 100's of times and yes, I am digging thru posts trying to find the answer... 

I am considering changing the bullet that I use on the 50 yard line from a 185gr SWHP to a 185gr JHP for the 50 yard line. The SWHP's would still be used on the 25 yard line. Is it okay to "switch" between the jacketed bullet and the lead bullet in the same barrel without doing anything?

A lot of people do it. To know for sure with your gun and loads, you will need to try.

A HM I shoot with convinced me to try just what you are asking about and so far it's been working just fine.

I do it. High master scores for years.

I prefer to load separate for long and short line.  Zero 185jhp and Zero 200swc.  When I am switching from slow fire to the short line, I run a .50 cal bore brush through the barrel followed up by a bore snake.  Is it necessary? I don't know but that's how I was taught by the HM who was doing it way before me.

I've been thinking about this very same subject. My concern is not going from jacketed to lead but going back to jacketed for the .45 match.
Anyone?

Thank you everyone for your replies. I am still considering this option. sixftundra, Could you give me an estimate of how much VV310 or Bullseye to use at the long line and how many "clicks" to adjust at the short line?

4.5 grains bullseye for the 185gr JHP'S
3.8 grains bullseye for the 200gr LSWC

Should be little to no adjustments between the long and short line.

4.5 of BE is a good load for the zero 185.
I use 4.4 of 700x.  It is what the gun was tested with.  Also it is easy to find, at least in my area.
When you start making them, remember to have the barrel of your wad gun with you so you can test the OAL.  You want the casing to be flush with the barrel hood.  Mine end up around 1.247.

3.8 of BE with a 200 LSWC is what I use for the short line.  Make sure some of the 'shoulder' of the bullet is exposed above the top of the casing.  Again, use your barrel to check.  I tend to have the casing just below the barrel hood for short line rounds to eliminate any feeding or lockup issues during sustained fire. 

Take your new rounds to the range and start out at fifty yards.  Get your red dot set right where you want it.  Put a mark on your elevation knob where it is set at.  Then head to the short line with pen and paper.  Sand bag your gun from 25 yards so you know exactly where the red dot needs to be to drill out the x-ring.  Take notes as you go.  You will find it to be anywhere from 3-5 clicks. 
I also make a two click windage adjustment but I think that has more to do with my trigger finger in sustained fire.

I brush and snake the barrel ONLY when going from jhp to lead.  Never the other way.  JHP like a barrel that is fouled and I have found that the first shot or two will be off call if the barrel is either clean or brushed and snaked out.

Thank you! Both Rob and sixftundra!
