429-421 Marlin Micro Groove

[EMC45]

Just shot a bunch of 429-421s out of my Marlin 94. They fed/fired perfectly. I loaded 6 with 5gr. Bullseye and it was very mild. Like a 2.5 .410 bore. They were accurate as well. Loaded a bagful at 22gr. 2400 and they were a good bit more stout! And twice as loud. Looked down the bore when I got done shooting the bore was clean aside from some old maids. No streaks or leading. I am casting from ACWWS clip-ons.

That is great. I think that big deep lube groove really helps on pushing them fast from a longer barrel. I have the ballard rifling, on a 20". I added the target knob Williams FP, that little shooter is tough to beat with a 429421 over a good charge of 2400 (I only went to 20g) lubed with NRA 50/50, man it works great.

Good boolit design. Looks like you have found a real winner. I am a touch
surprised that it feeds properly with that big square nose. Great news for
you.

Bulla, I have the same rifle (in stainless). Do you crimp in the criming groove?

EMC45, my Marlin has the Ballard Rifling, but I think that won't make big difference, where were you crimping yours?

I am asking because I have heard of others crimping over the front driving band rather than the crimping groove. When I get about to ordering a mould for this rifle, I am hoping that I can avoid buying a mould that won't work or isn't really the best option. I know that others have not been able to get this boolit to feed in their Marlins for love nor money.

I crimp in the crimp groove like this.........http://i298.photobucket.com/albums/mm243/Evansguns/102_2361.jpg

Nope the 429-421 W/ round lube groove. I took the Marlin apart and realized there was a little streaking in the bore. A few passes with a wrapped brush (0000 steel wool) and it is again mirror bright! That little gun is neat.

Wish I could get that bullet to feed in my 1894 :(

I have the 429244 and it feeds only when crimped over the top of the first driving band in a Marlin .444. Looks alot like that boolit.

Careful with that 0000 steel wool....you've only got one muzzle..and when it's gone...it's gone. I like nylon scrubbies for mine..works as well and not wear on the crown...In the pistols, a Lewis lead remover can't be beat. JMHO...Rodfac

I pull the bolt and go from the chamber. It is rare also. It is not part of my regular cleaning regimen.

429421 feeds through my 1894 marlin.
i was worried about that too
some people say it wont feed through theirs, but mine will feed them
10gr unique
8gr universal
20gr2400
all lube with lars BAC
mine is the square lube groove

Not too long ago I bought a new 1894 Marlin in 44 mag. It would not feed SWC loads. I read on one of the forums that you might need to break the edge on the chamber with a stone just a little and after doing that, it now feeds my 429244 & 429421 from Miha's mould - both are smooth & good to go. 429421 from Lee's mould is too long and the carrier will not lift. I understand there is a fix for that but so far I have not investigated that alteration.

I used a dremel tool with a round stone and just barely touched the chamber edges. Hardly noticable with the eye. But it feeds smoothly now.
