Load advice for newbie M&p owner

New M&p40 pro 5" owner, with KKM 40-9 conversion barrel. I am wanting to start reloading for 9mm and eventually 40. so I've got my saved brass, some cci 500 primers, some 147gr. Blue Bullets and Autocomp. Does anyone here have any advice or loads they like? Right now I just plan on going to Hodgdon website. I can also get 700x, 800x, and bullseye here locally, I just chose Autocomp based on webresearch that I can't say was all that helpful. If I could find Titegroup, I would. Looking to get into IDPA and USPSA.
Thanks for any guidance.

I've reloaded 40 using WW231, Unique and Blue Dot, I DO NOT recommend Blue Dot, both WW231 and Unique worked well. I don't have any personal experience with that bullet weight, so I can't recommend any loads.

Favorite powder for 147gr 9mm polymer coated bullets, besides TG?
Guys at KKM Precision said you really need to punch the bullet for it to seal and keep accuracy, but I've read that the heavier 147s like slower burn rates. These seem to contradict each other. Also, Hodgdon website has Autocomp (what I have to start) at #43 on burn rate chart, realoadersnest burn rate chart doesn't even have it rated. There are a lot more discrepancies between these charts. I am new, so what am I missing? Isn't burn rate pretty objective? How can these charts be so different?
Thanks.

I'm always amazed to see burn rates on different charts that are all over the place. Some of the differences are small, so I can see variances there, but I've seen one chart list a powder as being fast while another one rates the same powder slow.

The only ones you can really trust are from the powder companies, specifically the ratings of their own powders.

IMHO I wouldn't use the real fast powders like Tite Group behind a heavy bullet, slow burning powders are best reserved for heavy charges in magnum calibers, so I would go for a more medium powder like Unique as an example. Auto Comp is a little slow but if you already have some it might be worth a try.

Thanks a ton. I can get some Universal here locally, and it is one place behind Unique on the chart at #32, so maybe I'll try it. Question, if Autocomp is considered slow at #43, is it a good rule of thumb to "shorten" the chart, and consider only top 50-60 rated powders when defining slow to fast for 9mm or 40? That would put a powder like Autocomp in the slow quarter % and Unique right in the middle. I'm just trying to get baseline for judgement. I know in the end, it will all depend on how they perform, I'm just a tad limited by both local selection and I don't want to end up with 4-5 different powders just to get me going.

Thanks again.

Keep in mind this is my personal opinion, based on my personal experience...

I've loaded Blue Dot in 40 and it stank big time for that caliber, so based on that experience I wouldn't consider anything in that range for 9 or 40.

I was trying Blue Dot in 40, I had noticed a lot of unburned powder on my clothing, including the little blue dots included as an identifier. I went another day and was shooting over a white bench, after 30-40 shots I looked down and the entire top of the bench was covered with unburned powder, I could have written my name in the powder the coverage was so complete. After that experience I won't even consider using something that slow in those calibers.

Both Unique and WW231 worked great with no problems, my advice would be to use something in that approximate range for best results. Universal is right there so it would probably be a good choice.

If you have access to Bullseye, you may want to start with that. It has worked well in 9mm and .40 S&W for me, although it is a little dirty and not my go to powder for either cartridge. For competition (IDPA USPSA), the faster burning powders usually result in less felt recoil, allowing you to get back on target quicker. Not trying to insult your intelligence here, but be careful not to double charge a case. Sometimes difficult to see with the faster burning powders i.e. Bullseye, Titegroup, N310.

TiteGroup burns very hot and is generally not recommended by the manufacturers of lead and coated lead bullets.
For IDPA, do you want minor or major loads for .40? Decide what you want and work up the load. For 9x19, you're stuck with minor loads
All loads should be from reliable loading manuals and NOT from some one on the 'web. IN your case, you want LEAD bullet data. The Lyman manual would be your best source, but it may not have AutoComp.
You may just have to call Hodgdon and ask if they have data.
Next, believe it or not, loading for your gun is the same as for any other gun chambered for that cartridge. Even a load from the same make gun as yours may perform quite differently in your gun, due to variations in chamber dimensions, COL required for feeding, and lot numbers of components.
As above, most folks like a fast powder with a heavy bullet so the perceived recoil is more a push than a snap.
AutoComp: too slow. May be great for standard 9x19 shooting, but a bit slow for IDPA wants. 3.0gn may be a good place to start.
700x: meters poorly. Great powder, but you will need a really good measure.
800x: too slow. Even slower than AutoComp
bullseye: great choice. Start at 2.8gn and work up. You may achieve minor 125PF at 3.2-3.4gn.
I prefer AA2, 231/HP38, and Solo 1000.
For .40, if you stay below mid-range, AA5 is the most accurate powder I have found.

I shoot coated 125 SNS casting with Unique. However, I recently switched to BE-86 with better results.

The only issue with the poly coated bullets is the smoke. Not as bad as regular lead, but certainly worse than jacketed. BE-86 is less smoky than Unique and cleaner.

If you are going to use a slower powder, then you will want to load mid to upper range loads. Otherwise you get unburned powder and erratic velocities in my experience.

Light loads seem to favor faster burning powders.

With a moly or coated bullet, a cooler burning powder is your ally. Hotter dual-base powders contain nitroglycerin and burn at a much higher temp, and cause noticeably more smoke.

Cooler-burners are things like Solo1000, WST, and the holy grail of cleanliness: vv N320.

Regarding burn rate, faster powders recoil less. Fact. USPSA and IDPA shooters load a fast burning shotgun or shotgun/handgun powder (clays, Solo1000, WST, VV N320, Titegroup, etc) behind a heavy bullet for the softest recoil impulse and we drop to a lighter recoil spring weight.

I prefer a 13-lb recoil spring and a stock heavy striker spring and a 124-135 moly coated bullet for the M&P. The round nose profile of a 135gr from black bullets international can be loaded longer than the square shoulder ones with a flat point 124 and 147 grain profile, in an M&P... and the ability to play with your OAL more can really let you tweak a load for maximum accuracy and the perfect power factor from your gun. Additionally, many 9mm M&Ps will not shoot 147s worth a damn when equipped with the factory barrel. Hot 115s (1100+ FPS) will shoot group sizes 1/3 as large as a sluggish 147 (900 FPS) from the same gun. Some guns eat them, some do not.

Mine has been hand-fitted with an Apex semi-drop-in barrel and it now groups good 147 loads just fine, but I prefer the faster-cycling slide I get from a 124, 130 or 135 grain bullet.

Also? These days, it's down to which suitable powder you can FIND. I have an 8-lb jug of Solo1000 in the attic that's my favorite powder for coated bullets. I'm working with Clays and WST because I found them in stock somewhere. I'll probably work up a load with Ramshot Competition (another fast-burn shotgun powder) soon, because online retailers stock it and others have had good luck.

Something to note: These fast-burners run out of ability to safely push a 9mm load right about where they make power factor and run reliably in a competition reload: pressures are approaching +P, or are IN that range with things like VV N310 or Clays, just to make it to 130 power factor. If you're wanting to cook up a thundering defensive load, you'll need a slower burning powder like HS-6 or Power Pistol or the like. Different tools for different tasks.

And... why go to all of the trouble? Well, shoot a few matches and then switch to your buddies Titegroup/FMJ or VV N320/lead bullet loads and do it again. The giant grin on your face? That's why.

Thanks for the replies. I shot the first rounds today. Since this is the first time I've loaded 9mm, I really didn't have anything to compare recoil to but Win white box and self defense Ammo, but it was noticeably softer than WWB. After getting data from hodgdon website, I loaded up 10 each of 3.7,3.8, and 3.9 grains of Autocomp under 147 blue bullets with cci 500 primers. According to Hodgdon, these should be right at PF. 3.8gr grouped 3.5" at fifteen yards. The others slightly larger. Now I have to mill a frame to rig my Magnetospeed sporter to and install the apex fss trigger kit. I will get some different powders and continue testing, but I have to say I am tickled so far. Loading for pistol is more fun than for long range precision.
