AA 5744 Experience

[Loggy]

I bought a Model 10MLBSS-II and been shooting the SST 250 grain bullet w/45.2 (3.4 Lee Dipper) and getting good accuracy and ave. of 2,260 fps.

Has anyone shooting AA 5744 with the SST increased their loads past the 45.2 grains and what has been your experience? I just bought a powder scale and have some more flexibility now.

Thanks

Loggy, you broke down and bought a scale!
If you get to messing with the Savage very much you really do need one.

:)Loggy, Mike 3132 and I have both shot up to 48 grains with a 300 grain bullet with problems and good accuracy. 5744 has proved to be pretty accurate but no speed demon. Maybe with the new 3 hole vent liner more velocity will be realized with less powder. When shooters on this board first started using 5744 they thought it was a little slow as there was some unburned powder left behind or blown out the barrel. I found 45 grains to be very accurate with 300 grain bullets in my ML-1.

[Loggy]

Thanks Predator II. Sounds like anything past the 45 grain load may diminishing returns as far as accuracy/powder burn. I only have experience with the one hole vent liner so far.

Any idea of energy generated at muzzle and 100 yds. by the 250 SST & the 2260 fps I'm getting with 45 grains ?

My Manual lists 44 grains of 5744 w/the 250 Hornady XTPat 2,267fps & 2.837 fpe but nothing on the SST.

Thanks.

I just posted on a link to FREE Point Blank Software but here it is also!

5744 is a fine powder for 10-ML use but as has been mentioned it will not set any speed records.

It does have a very important use. Some of us can't cram sabots in if they take much effort to push down. For those who have to have easy loading ammo using a very loose quick loading sabot poses some problems in the 10-ML.

If a normal load of another powder is used it is subject to ignition problems. Either vertical stringing or even misfires are possible.

Because 5744 is a large case black powder replacement powder it has to serve in cases where there could be a large air void. For this reason it has been formulated to ignite under almost any circumstance. So if you are a little long in the tooth or have other strength loading issues using 5744 and a loose sabot will work great for you.

I'd suggest many other powders for other stronger hunters besides 5744.

RB,

I don't think I recall you mentioning 5744 in Duplex loads, does it fill any need ? Perhaps with very light bullets?

[RBinAR]

I did use it in the loads and it acts very much as N110 or Imr-4759. Of the three however. N110 burns much cleaner and is of a better (smaller) size for duplex use.

But it is good for light weight bullets in loose bores with just about any type of load.

RB: Like I mentioned I'm loading the Hornady SST. I use the Hornady sabot that comes in their pack. The black stepped cupped base. Not sure if I meet your definition of a "stronger hunter" or not but I have no problem loading this bullet. Was merely trying to get some input re others experiences with the 250 SST and AA 5744.

Yes you do meet the criteria. You are able to stuff normal loads down the barrel.

5744 is a good powder and I say that having hundreds of shots fired with it. If it's accurate and you like the load it produces as someone once said "if it ain't broke don't fix it.

With the 250 grain SST I've gotten fine accuracy with the maximum recommended amount of 44 grains at 2250fps. It's a good solid light kicking load.

The reason I mention other powders is because most shooters would like more speed if possible. Many powders offer that speed above 5744 with as good accuracy. Speeds up to 2650fps are easily obtained with the right load.

Still speed isn't everything and other shooters with needs beyond speed will always find 5744 to be available to cover those special needs. ;D

[Loggy]

Thanks much RB. I started with & only have experience with the 5744. I didnt want to get into sub bases or duplex loads (Yet ;D). Do you have any suggestions for another powder that is a little faster that would work well with the 250 SST/Hornady sabot not requiring a sub base.

Thanks,

Loggy

Loggy:

For no sub-base loads either N110 or Imr-4759 will shoot cleaner and faster than 5744 with just standard loads. More people will attest to N110 but 4759 has its' followers also.

Those powders are about it for the single hole vent liner. However if you have the three hole liner or can get it a whole new world of powders and performance appear. With the three hole liner H322, H4198, N120, XMR-2015, Alliant Reloader#7, Imr-4198 and possibly a few more may shoot accurately. Most of these powders will shoot past 2500fps with very good accuracy using the three hole liner and the 250 grain SST. I personally like 2015 and H322.

[Loggy]

Appreciate the info RB. Starting to realize there are alot of load options with the 10 ML-II

My dealer carries the IMR4759 but not the N110. I saw over at HP ML ballistics for 43 grains IMR 4759 is 2,330 fps & 3,015 fpe for the 250 grain SST. Do you think a sub base would be needed with this load?

Probably not: you generally don't have to think about sub-bases until you get to the 2400fps speed. But it does vary with the rifle and this level is close to the maximum without a sub-base.

Loggy,

47 grains and 250 grners was the best weight I found w/ the AA5744.

Good Luck!

Hey Loggy
Just be sure to weigh your dipper charges. My dippers are way off. Now for the important item What is the easiest climbing treestand to use for a guy in his sixties with not the best knees.

A ladder stand :-)

I use to have a summit viper -pretty nice.

Loggy,
I've been shooting your load (250SST with 3.1cc dipper of 5744) and havne't benn getting good accuracy. Are you using the one hole vent-liner or the 3 hole one? And do you use a subbase?

I hear ya as far as ladder stands go, Pretty nice once you get them up. I would like something a little bit more flexible.

Redclub: I just got a scale and your right there. Thanks!

I been using the Loggy Bayou Climber for years. Its light and solid as a rock with 2 platform lock to tree points. The hand climber can also be used as stand-up sit-down climber or just hands. I've seen guys that were not in the best of shape go up a tree like nothing. Of course, safety strap is on before those tootsies leave the ground. ;D

Buff, I have the one hole vent liner and use no sub-base. I'm measuring with the 3.4 dipper (45.2 grains)

Hi Loggy
Thanks for the info I will go check them out.
For a good number of years we used climbing spikes and worked very well however in Wi. the trees freeze and it can get quite dangerous.
Redclub

[Loggy]

Redclub: Your welcome. The Loggy will lock to tree in bad conditions. On the climb in ice it can be tricky though. When you reach your height and lock swing up seat ratchet strap on, aint no comin loose. Most climbers only have one platform lock point to tree. Loggy has 2 as mentioned.

Good Luck!
