9mm Lead Flat Point 147gn
I am pretty sure I am doing it correctly and I do have a short chamber. But it seems like no matter what I do my 147 LFP's do not pass the plunk test unless I load the bullet to about 1.08 to 1.09 OAL.
I was using Brazos and ordered some Bayou Bullets to test and the Cannelure on the Bayou seem a little better then the Brazos.
I was loading 3.5 gns w321 I got pressure signs and Leading but the bullets shot like lasers. Loading over 3.3 W231 , sill pressure signs, less leading but with reduced accuracy as compared to 3.5gns.
Loading over 1 CH under 3.1 cycled the gun fine and no pressure signs to be concerned about and is pleasant to shoot.
I think I am crimping about as much as I need to , Max before resizing the bullet in the case.
Has anyone had this experience with 147gn LFP? I like the bullet but do not like the idea of loading that short? Currently about 1.08 versus 1.10 to 1.12 suggested. I do have a Walther factory barrel 1:9 that I can load longer than the Jarvis Barrel 1:16 twist but I feel like 1:16 could be accurate????
Does 9MM LRN have a better Cannelure?

Yes I was getting groups like that out of my PPQ. I think the Brazos is a little different then the Bayou. 3.5 BE should translate to about 3.0 W231.
Magnus is fairly famous for that bullet and 38 super I seen them group under 1 inch at 50 yards with a really well built 1911.
What Barrel is that 952 or 1911? My Barrel is a Jarvis 1:16

952. It has a 1:18.75 twist. I've got some other groups here with the RO 1911. It shot pretty decent with factory barrel and even better after I fitted the Briley Bushing and replaced the slide stop. The RO is a 38 super now and still likes those 147gr LFP.

How was fitting the bushing? Seems like a good Idea?LenV wrote:952. It has a 1:18.75 twist. I've got some other groups here with the RO 1911.

I have some 147 grain FP’s on order from Summit City Bullets https://summitcitybullets.com/9mm-bullets. His add states this bullet design will work with short throated barrel and that’s a big reason I ordered them plus all I have read said he makes good bullets. It also lists a 147 RN with the same claim.
The 147 FP polymer coated bullet I have from Bayou bullets looks very similar and will feed with it seated at 1.125 and it might need to be another thousandths to be a little more “plunkable”. I’m getting a 133 PF with VV N320 and the accuracy is good from a CZ Shadow 2.
When I get the Summit City bullets I will post back with how they load and shoot.

Brazos 147gn still left lead in the barrel after about 20 rounds, Going to try Bayou which loaded about .03 longer 1.10 - to 1.11 versus about 1.07 to .08 for the Brazos.
I figure at 3.1 W321 and the Brazos was sized .357 if I recall; should have had no leading.
Although the bullets look identical then you look at them close the Bayou Bullets have a slightly more slender ogive.
