Does this mould drop a good boolit?

[Kermit2]

I'm looking at an RCBS 45-225-RN two cavity mould. I already have a Lyman 452460, but am looking at adding a round nose mould to my bag of tricks. Does this mould drop a good boolit? Do these boolit's tend to shoot well from most 1911's? I noted that it doesn't have an obvious second driving band like the RCBS 45-230-RN, but it does look like the diameter of the boolit is the same above the grease groove as it is below. I'm also looking at a RCBS 45-230-RN. Is it a better boolit than the one mentioned first? All information on these moulds / boolits will be appreciated. Thank you!

Kermit2-

For the money, to work up a good target load in your 1911, you can't beat the 6 cavity Lee copy of the H&G 68. Its a 200 grain target design that casts, loads, and shoots as well as my MiHec version. Just my $.02 worth.

PS- I have 3 Lee 45 molds.

The .45 200 grain SWC is a good boolit. I have a Lyman 452460 200 grain SWC mould. I'm looking for a good 230ish grain round nose mould and found both the RCBS 45-225-RN and RCBS 45-230-RN moulds. Just having trouble figuring out which one is better or if both are good. All those with expericence with these moulds your help and advice will be appreciated. Thanks!

RCBS molds are generally excellent. I have read that the RCBS roundball load feeds better than the Lee does, but I never cast rn 45 boolits, my H&G 68 clones get all the work in that catrgory.

I can only find a truncated bullet in .45 with a weight of 225 grain. The RCBS number is 82091. The 230 grain RN is RCBS number 82048. I would go with the 230 gn. Round Nose as that is the bullet the 1911 was designed for.
The round nose should feed better and has enough bearing surface to stabilize the boolit.

The RCBS 225 grain RN is one of the four differently designed bullets I use in my 45ACP work. It is almost identical..almost a clone of the H&G #34. It feeds flawlessly in the 1911's. It casts easily. The two bands are in my opinion are an advantage as they do provide a longer bearing surface to stabilize the bullet and grip the rifling. It also works well in revolvers either in the 45ACP or the 45 auto rim. It performs well as a target bullet, but does not cut clean holes in the targets like the SWC designs. RCBS mold quality is excellent (although the largest molds produced are only 2 cavity) and it is backed by a rock solid 100% guarantee. LLS

don't overlook a 225gr rnfp 45 colt boolit mold.
they generally will pour a little bigger and size to 452 easily.
they feed in a 1911 perfectly also.
ignore the crimp groove.

The RCBS 45-225-RN that I'm speaking of doesn't seem to have two driving bands. It has the bottom driving band, then the grease groove, and then the nose of the boolit begins. It does not appear to be of the same design as the RCBS 45-230-RN. Seems similar to the Lyman 452374 mould. The mould is stamped RCBS 45-225-RN Here are photos of the mould in question:

Any information on this mould will be appreciated.

lyman makes one like that also if the area in front of the lube groove is of sufficient size that the lube doesn't leak from around there they do very well.
sometimes that area is small like 449-450 small.
i had the lyman version and never bothered to cast with it.

Yep, there are two RCBS RN designs. The older one is a 225 grain design that is very similar to the Lyman 452374. The newer RCBS 230 grain design has a front drive band that is offset from the ogive of the bullet. Many of those RCBS 225 grain molds dropped bullets full diameter above the lube groove however some of the recent Lyman 452374 molds had/have the issue of being small in diameter above the lube groove. I have a old Lyman 452374 and it drops .454 on the base band as well as above the lube groove. It is also a bit shorter and the ogive isn't as pointy as the newer Lyman design.

I don't know if the old RCBS 225 RN is more like the older Lyman design or the newer one.

Down the page a bit is a nice pic of the new RCBS 230 that forum member That'll Do posted.

Looking at this pic it would appear that the RCBS 225 is more similar to the older Lyman design

Kermit:
Buy the RCBS 230-CM mold and don't look back. I haven't seen anything the round can do the CM won't, and the CM will hit a lot harder.

RobS,

Bless you. The photos you provided in your reply are excellent. The mould I'm looking at purchasing does appear to cast a boolit that matches the boolit on the left in your photo. It appears to me (but I'm not too smart about such things) that the boolit on the left has more full diameter surface area above the grease groove and would engage the rifling better. The more I look at it the more I believe that this boolit should work well. Other opinions and thoughts are appreciated.

+ 1 for the RCBS 230-CM mold!It work great.

I too believe the older RCBS 45-225-RN will have full diameter above the lube groove. I have very good accuracy from the Lyman RN boolits my mold drops out anyway.
