.45 cal question, been a while!

[esshup]

Hi guys. It's been a while since I posted. While I've been playing with the Savage ML since around 2002, I basically just use it for hunting. I've had great success with the original ML-1 (modules) & still have it, switched and bought a ML-II from Dwight that RB in AR did some work on, and ended up swapping the barrel from 50 to .45. For a number of years I shot the Barnes with the blue sabots in the.45 barrel pushed with a load of H-4198 that some here had problems with the sabot blowing, but with the high loading force I wanted something easier to load.

A buddy has a swinglock sizing die set to make bore rider .45 cal bullets, and I got some .45 cal 325g Pittman Aeromax bullets. While they fly really well, and they kill deer phenomenally well, at closer ranges if hitting bone the meat loss is too great @ the 2700+ fps they were moving at. Think of a soccer ball sized hole missing from the exit side of a deer.

I have a BUNCH of the T/C Shockwave 250 grain .45 cal blems. I was thinking of trying them in the .45, but only at 2300 fps or so MV to stop them from acting like a varmint bullet (I remember back when guys were pushing them super fast and them blowing up). All of my shooting at the current property that I hunt is under 220 yds.

Is this a feasible idea? They will be sized to be a bore rider, and will 2300 fps or so be enough of a kick in the butt to get them to obdurate?

If so, do ya'll have any suggestions on where to start with a powder charge and powder type/name? I'm comfortable with duplex, so that's not a problem. I have a lot of different powders here, so about anything is fair game.

Thanks for any help or suggestions you can offer.

To get the 250gr down that slow you will drop peak pressure a LOT with 4198. The FTX/SST likes a good wack to get it to obturate. Duplex or consider a faster powder with possibly a little less speed. You can get in that speed range pretty easy with around 55gr of N120 and a 300gr SST. That will be a sub 45kpsi peak load but over 40kpsi. N120 peaks a bit faster and a bit higher but its not the best for a 250gr bullet either.

Sticking with 4198 i would look at the Fury bullets. Easier to bump up and bonded jackets. Starting at $44/50 they are a good value.

Maybe 10-15gr/N110 and 45gr/4198 could get around that speed for a duplex. N110 peaks fast and is very temp stable.

You might find that 40+- grains of N110 would get you the pressure and velocity by itself.
5744 though dirty, should be in the same ballpark.
4227 but you would need about 5 more grains.

Just suggestions, since while these all give about the same velocity and pressures, which give the best accuracy is probably the goal, and these guns can be fickle

I would go with N110, shot very well in my .45. IIRC 42gr was approx. 2450fps with a 250 SST/FTX.

42gr of N110 250gr sabotless in a 45cal is gunna really be up there in peak pressure.

Thanks guys, I am not tied to any one powder, I have a whole bunch of different powders on the shelves since I reload for a bunch of different cartridges.

Wasn't VV-110 known for possibly falling back thru the vent liner? Still running the ariginal type VL's in the the .45.

Photobucket sure knows how to screw things up don't they?

edge; so no more throwing the kitchen sink at it? LOL

I'll try VV-110 at 38g to start and run them over the chronograp and shoot paper at the same time just to see POI. I'd rather start using what components I have on hand vs. buying something new to try - I gotta start thinning down the herd so to speak. I've got bullets and powder that I'll probably never get to.

[Dave W]

Lil Gun was the one that most mentioned as flowing through the vent.
35-38gr should put you in the 2300fps zip code.

The "hyperlinked" traces can still be seen. Navigating them takes some getting used to but the traces are there.

53B) 42gr and a 225gr FTX for example is over 42kpsi.

Thanks guys, I have VV-110 here. It's in those 2# containers. Yeah, I've had it a while!!!

[dannoboone]

Still working on one of those 2# containers as well (for duplex
loads only). Got it for less than the cost of what they are
selling one pound containers now.

Wondering if you might have a 50 Cal Savage barrel. Thanks John h 423-291-97670

I wouldn’t consider this load! Not in a 45 retrofit barrel.

Out of curiosity, 2700’/sec with a 325g AccuMax (PN45 retrofit/10ML2). What was your load?

Take a look at Fury 452 bullets for resizing and consider 60-65g H4198, assuming you’re using a conventional 209 ignition.
