trucated cone and accurate no. 5 for 1911

[T-Bones]

anybody know of any reloading manuals that have 225 grain truncated load data in them? for lead or hardcast bullets? For .45 acp? I have some 225 grain flathead bullets, from missouri bullet co. and need data for them. none of the manuals I have access to, have that weight or style of bullet. The pistol for which I am loading for is a RIA 1911 G.I. I have made up dummy rounds, and the maximum oal for my gun is 1.211" with this bullet.

lee modern reloading second edition states 200 grain lead bullet (I assume round nose. Didn't specify) 7.8 - 8.7 Accurate No.5 min oal 1.190" would it be safe to use that load and the max oal of 1.211"

lee modern reloading first edition has 220 gr data. but none for AA#5 powder. but does list 200 gr and 230 grain loads. again I believe round nose, with AA#5 8.1 - 8.7 grains oal 1.190 for 200, and 7.8 - 8.5 grains oal 1.230 for 230 grain bullets. of course the 1.230" length is to long for my pistol.

lyman cast bullet handbook 4th edition has data for a 230 grain truncated bullet. but none with accurate no. 5 powder.

I did find a load on handloads.com which stated 7.9 gr AA#5 850 fps oal 1.207" WLP. the source was from a guest.
not hodgdon, alliant, speer, ect. so not sure if that would be a good start load or not.
Any help I would appreciate.

MBC 45ACP bullets

For MBC 225 gr TC FlatHead bullets, I used 1.190" to work with my barrels and referenced load data for 230 gr lead bullets. If you look at the comparison picture above, 225 gr and 230 gr bullets have comparable bullet base lengths so even though 225 gr TC bullet is seated shorter at 1.211", it should have comparable bullet seating depth with 230 gr RN bullet seated to 1.250".

maximum oal for [RIA 1911] is 1.211" ... lee modern reloading first edition ... with AA#5 ... 7.8 - 8.5 grains oal 1.230 for 230 grain bullets.

Current Accurate load data lists the following. For your shorter 1.211" OAL, you could use more conservative charges for start/max as you can always go up. How about starting at 7.0 gr and working up to 8.2 gr?

Thanks bds for your advice. you have been very helpful.

I shot a bunch of Magnus 225 gr bullets that looked just like that (Probably the same mold). (5.0 Grs W-231). You can use any 230 gr lead data as long as you don't load them real short.

thanks walkalong, go to know.

Think I will try some AA#5 at 7.0 Grs and my max 1.211" and see how that goes. Thanks to all that replied.

 

[Walkalong]

I loaded those @ about the same OAL (1.210 to 1.215). If you can hold them all to 1.211, I'll be impressed.

 

[T-Bones]

my loads usually come out + or - one and half thousandths. in this case 1.210 to 1.213. The 1.213 will fit. So my max is actually a little bit longer than I thought. so that's good.

T-Bone. If you are interested, 8 grains of AA5, and a 230 gr cast RN got me about a 825 fps avg from my 4.4" SIG P220, and about 855 fps avg from my 1911 when I chronographed them. This was from 1995, and I even loaded some with 8.5 grains - The SIG got about 865 fps, the 1911 about 885 fps. I'd guess your rounds will be around 700-ish. That 225 TC is a nice bullet (Mastercast from PA are the ones I used), they feed well, and are accurate. Good luck.

That is good, the seater stem must be flat or made for that bullet style (Truncated) and only the flat of the stem touches. That will give very low spreads like that. Seater stems that contact the ogive on rounded bullets are harder to keep such a tight spread with.

well I had a chance to test my loads. And I got 2-1/2" to 2-3/4" groups. At 7 yards from a rest.
I always like to shoot from a rest first. Then shoot offhand. I did have one failure to feed. The slide did not go all the way forward. When I checked the round it looked like the bullet had slid forward in the case. What can cause that, And how to keep that from happing? I first thought of the crimp. I had the loads crimped to .470 or .471". Thanks for all the help so far.

If this really turns out to be an issue, and necks are clean, no oil, etc, you are going to need more neck tension. Bigger diameter bullet, smaller expander, thicker case walls... I have seen a commercial caster spray silicone lube on finished bullets, and this certainly doesn't help. "crimping", as in taper crimping, is there to simply remove belling, and not act as an actual crimp (bites into bullet/folds down into cannelure. Over use of a taper crimp can actually make the situation a lot worse; Swage the bullet down in diameter, the brass case springs back, but the bullet retains its new, smaller diameter. Lots of folks are guilty of this, trying to fix the issue.

I have also seen where folks will apply a pretty aggressive case cannelure, that stops setback.
