Gentlemen,I read in an older post of an RCR sabot. Could someone explain. Also,do more of you guys like the Harvester sabot over the MMP? My 10ML11 is new with only 47 rounds through it. Do any of you feel that there is a breaking in period before the rifle really settles in? Being that this a stock model,what in your opinion's would be the best thing I could do to improve accuracy. Meaning adding a 3rd pillar,bedding etc.... Thanks for all the info

The sabots today are much better then say in 2000-2003. In 2003 that is when a big change in the plastic they used happened. When Harvester started producing the crush rib they may have improved a little bit over the MMPs as far as being able to take the heat.
As far as breaking in if you use sabots there is no "breaking in" like with a centerfire. The best improvement is with the shooter as you learn and refine your loading and shooting technique. Then maybe bedding is the most bang for the buck.

RCR is Red Crush Rib sabot and as rossman40 stated they are better formulated today.
The RCR is for . 451 and .452 bullets in a Savage barrel that is usually on the looser side than other muzzle loaders on the market. You have to play with all the different sabots and the bullet you want to use to get a good snug/tight fit for better accuracy. Remember tight is right.
Other things that help with accuracy are as follows and in the order you should probably do them in.
1) Once you have a good sabot bullet fit then establish a goto load that always shoots
consistently for you. Then if need be begin your accuracy changes. (I would choose a goto
load that is a Savage book load and you may even want to use the Hornady XTP bullet until
you get more comfortable with your gun.) (Try to eliminate to many variables from the
equation)
2) Lap the barrel with JB Lapping Compound to help smooth out the rough spots. (Acts like
barrel breakin)
3) Make sure your goto load that always shoots consistently for you. Is working and mark the
improvement if any. Then if need be continue your accuracy changes.
4) Bed the action and if you so desire you can Third Pillar it. The third pillar is more for keeping
POI in the same place. Because with two pillars when you loosen the rear action screw to
clean your gun you almost always move you POI. Others have solved this problem by getting
tools that can remove the breach plug without removing the rear action screw or the bolt.
5) Make sure your goto load that always shoots consistently for you. Is working and mark the
improvement if any. Then if need be continue your accuracy changes.
6) Probably experiment with different bullets and sabots.

I like the Barnes Original 300grain. It shoots AOK with the MMP orange,but would like to possibly improve accuracy if possible. Those red vrush would be too small. Thanks

Your barrel may love the Black crush rib/barnes original combo. Many seem to.

Your barrel may love the Black crush rib/barnes original combo. Many seem to. Thats been my experience also, if the MMP Orange is just OK, then try a black CrushRib. The MMP Orange with a Barnes O comes out to about .504 OD and the CR is a bit more but loading pressure isnt that much harder. Red Crushribs are really large with just a .452 so it might be really tight depending on your barrel. |

You can also try the smooth black harvester or MMP with the .458 bullets. My gun likes them even better than the Black Crush Rib. I shoot the .458 Hornady HP #4500 and the BO's.

Bedding helped mine enough that I didn't do anything else, up until the .45
PacNor went on it. If you haven't already, check to see if there is good
clearance between the barrel channel of the stock forearm and the barrel.
"Red Crushribs are really large with just a .452 so it might be really tight depending on your barrel."
That statement reflects the main problem with about all ML barrels -- no two
are close to the same. Even 10ths of thousandths make a difference in
accuracy. Loose barrels, tight barrels, all make the demand on each of us
to come up with the right combination for our particular barrel. Many of us
have had to find one particular sabot/bullet combo to fit a barrel. Sometimes,
it helps to also knurl bullets at little as .0005. Krazy, huh?
