I want to try cheaper lead bullets from MBC. I also heard they feed well in full size 1911

mBC have 4 different SWC for 45. Which one to get?
 
Personally of the SWC's listed I like both designs. They both feed well in my stock 1911, and they are both accurate as all get out. Both of the designs have been around a LONG time. if you do a little searching on the HG molds you will find that the 68 has a great track record, as does the 130.

As for which weight is best, only you can decide that. I like the 200gr weights in mine, but that is simply a personal preference. I just feel it is an in between weight and while I normally shoot the 230gr weights, the 200's hit right in there with them.

The biggest thing you should concern yourself with is which powders and what OAL your going to use. Once you have those figured out, the rest will take care of itself. If in doubt order some of each and go have fun.

That would depend on the barrel/powder/charges used. Slug your barrel and if the groove diameter is .451", you should be fine using both 12 and 18 BHN SWC bullets. If your barrel's groove diameter is .452"+, I would recommend using the softer 12 BHN SWC bullets.

The harder 18 BHN 200 gr SWC (IDP #1) and 185 gr SWC (IDP #3) bullets will shoot accurately without leading in Sig/RIA 1911 and M&P45 even with lighter target loads but with oversized Taurus PT145 barrel (.455"-.456"), the same bullet loads will produce erratic shot groups and leading.

The softer 12 BHN 200 gr SWC (Bullseye #1) bullet, even with light 4.0 gr charge of Red Dot/Promo and 4.8 gr of W231/HP-38, will produce accuracy and minimal leading in Taurus PT145. Of course, the 12 BHN loads work fine in other 45 pistols.

If you are planning to use lighter target loads, I would suggest you start out with Bullseye #1 (12 BHN 200 gr SWC) as 200 gr SWC bullets have longer bearing surface (part of the bullet base that rides the rifling) than 185 gr SWC bullets.
 
bds,

I have Kimber Custom II. Unfortunately, I don't have micrometer and not planning on checking barrel size of yet.

I will be using BullsEye powder to load. Seems like I need to try 200gr first (for more area)

Which particular 200gr SWC you suggest to start with?
 
Katitmail, I shoot with a friend who has several Kimbers and both 12 and 18 BHN (Bullseye #1 and IDP #1) bullets shot well without leading.

Since the softer 12 BHN 200 SWC bullet will work better with lighter target load powder charges (especially with lower charges of Bullseye powder), I would recommend you start with Bullseye #1 bullet.
 
The 200gr SWC from MB works great, but I've switched to the 200gr RNFP as the H&G68 doesn't always feed so well in non-1911 pistols. Using the LEE "factory crimp" die I've had no issues with setback having shot many 1000s in a variety of 1911s and other .45ACP pistols.
 
Katitmail, I would agree with Brad that the 18 BHN IDP #1 SWC bullet would work well with your Kimber and Bullseye powder for typical loads, including full-power loads as you probably won't have the oversized barrel issues.

For your pistol and particularly Bullseye powder, which can produce accurate lower powder charge target loads, the 12 BHN Bullseye #1 will give you the additional option of trying out lighter recoil yet accurate target loads.

I have done side-by-side comparisons of 12/18 BHN 200 gr SWC bullets with Kimber/Sig/RIA/M&P pistols and got good results from both bullets.

wally, my 185/200 gr MBC SWC loads have all fed/chambered well in Kimbers, tight chambered Sig 1911, RIA/M&P/PT145 pistols that I have shot. Of course, the 200 gr RNFP loads fed like 230 gr RN and is an excellent alternative for pistols that won't feed SWC bullets reliably.
 
For IDPA I need to make 165 power factor, I'm not sure if it's "light target load" or not. Probably not on a strong side.

Will see. I ordered couple hours ago - got email that it is shipped :)

Today I'm going to chrono some loads I made with RMR 230 RN plated bullets and see how they work, but ideally I would like to run lead in this gun.

I wanted to try RN first to make sure gun works good. WIth Reiner HP bullets I loaded (1000 of them!!!) it doesn't like to feed every time :( I guess I will use those rounds for practice. When I shot this gun with factory ammo it was eating it OK.
 
Kat,
You will need to get 830fps minimum to meet IDPA PF, that will give you PF 166, too close to the wire for me. A friend just chrono'd a 200gr LRN with 5.0gr BE for about PF 168, I advised him to increase to 5.2gr.

I load 200gr LSWC with 5.5gr AA #2 and get PF 175 without excessive recoil.

Both results above were with 5" 1911. Work up your loads and chrono for yourself to be sure.

Good Luck

I use the bullseye #1 for my slow fire load over 4.2 grains of bullseye powder for 45ACP. It leads a little, but not too much. It's accurate, but my 1911 gets it hung up on the barrel ramp...it nose-dives into the edge and locks things up. This is not common...the bullseye #1 is likely the best for reliable feeding, but my match gun just doesn't like it enough.

The button bullet (185gr) feeds great, again which is odd, because it has a very short profile it should have some feeding issues. It doesn't cut holes as cleanly, but it is my timed/rapid fire bullet because of the flawless feeding in my gun. I use 3.6 grains of bullseye in 45 ACP. Very low recoil load, and it short strokes with a GI recoil spring.

My GI replica load is 4.6gr of bullseye with their 230 grain softball bullet. It leads like none other, but it's cheap, and I use it in my carry gun to replicate my carry load. It takes an extra few minutes to get all the lead out of the barrel with a chore boy on an old brush. I found this easier than trying to find a load that doesn't lead up as much. Some day I'll try harder.

The "best" L-SWC for the .45 Auto is the H&G "long nose" #68 and clones.
The Bullseye #1 is the one you want. The "button nose" 185gn bullet is OK (I haven't had any real success with the 185gn "long nose" SWC).
You don't need or want an 18BHN alloy in .45Auto. Heck, 12BHN is still too hard, but better than 18.
 
I ran the IDP#1 for a long time in my guns. Never had leading problems as they had good bore fit, though IMO they are harder than needed for 45acp. I recently switched to the IDP#4-XD, the 200gr RNFP and really, really like that bullet.
