I was looking at BCR's and i do not see one for .458. The red says "for smokeless", but the others do not. What's the difference between the red .452 and black .452? I shot some BCR's that that shot good, but now i am all out and want to order some for testing, but now i am wondering about the "smokeless red". I am shooting .458 300gr.
And, there is a "long" BCR for 300gr. or more? . I shot BCR's before, but i did not know there was a "short" and "long", whatever i shooting was past the ogive.

We are using the BCR (.452) for .458 dia bullets with great success! Rossman stumbled across this great discovery! Most find that the BCR when used with .452 dia bullets provides to loose of a fit.The RCR has a outstanding record with .452 dia bullets.

I wonder if anyone has tried the red? |

I have used the RCR with .452 bullets, tighter then a HPH-12 and seem to do the job

My SMI loves the RCR with .451-2s.

I think you would have to have a loose barrel spec wise for them to work. They are thicker than the blacks. If you've tried the blacks with .458s and they are too loose, trying the reds wouldn't be a bad idea.

I can barely get .452s down my bore in a RCR!

I do have a 50 cal barrel that I got from Richard that loves .458s and a Harvester short smooth black. My current .50 likes the same smooth black but with a knurled .452. Point is try any thing that goes down your barrel with good resistance till you find what IT likes.

I just knurl the bullet if I need/want a little tighter fit. The black smooth will probably be too tight with a .458 unless you have a really loose bore(like one of mine). You will probably want to try the black Crush Rib (BCR) without knurling. I think it is the better fit in most .50s with a .458 bullet.

Thanks, this sounds like the way to go other than the Orange MMP's. I still want to try knurling BO's in the MMP's, as the BO's are a hair looser in them than my horn. #4500's. |

To clear up your first question, In my experience I have shot the Harvester red, black and green sabots and they all will stand up to smokeless powder. That is one good thing about Harvester sabots. They come in a smooth version and a crush rib version. Crush ribs are supposed to load easier because there is more give in the petals therefore called crush ribs. ML barrels can vary some in size so to get a tight fit this is basicly what most of us have found that works. The black crush ribs work well with .458 dia bullets. For the .452 dia bullets the red crush ribs will work and give a nice tight fit. If it seem that you have a tight bore and the red go down too hard then the black smooth would be in order either long or short. If you use the long you will have to trim them with the 250 grain bullets. You trim them so that your ramrod or spin jag don't get hung up on long petals and pull the bullet off the load. Personally I order the long and trim them off at the ogive and that gives me a tight enough fit in my gun. The green smooth sabot is used with 44 cal. bullets of .429 or .430 dia. and I have used them successfully also. The green crush ribs I have tried but are too loose for my purposes. Knurling is something I do to get the fit just right so you can get a good tight fit but with out using a bullet/sabot combo that you have to take extreme measures to get seated. If the bullet/sabot goes down extremely hard you can start to distort petals and that could effect accuracy. Just my experience and hope it helps. DH

I have not thought about the distorting petals before. My orange MMP's go down pretty tight @ 50lbs. I noticed the BCR's with that same bullet were a good bit tighter, although i have not checked the seating pressure yet. |
