    I'm new to reloading and one of my quests is to make a softer shoot for Mrs. Collector as she goes up in caliber.
    Here's my question in the simplest of words. Given that the powder is equal, does a lighter grain bullet (ie. 115 gr.) shoot softer (less perceived recoil) than a heavier bullet (ie. 147gr)yes? No? no difference?

    The heavier bullet will have a perceived softer recoil or flip. The heavier round tends to push more strait to the rear instead of flipping up.

    The powder charge would not be equal for 115 vs 147. The heavier bullet sits farther into the case therefore requiring less powder. However I would tend to agree with the above statement on recoil with a heavier bullet.
    Use reliable reload data from the manufacturer and they show the min and max loads most of the time. The min loads will all be powder puffs.
    For example from Alliant's reloading book:

    115-gr Speer GDHP Power Pistol CCI 500 Speer 1.125 6.7 1212

    147-gr Speer GDHP Power Pistol CCI 500 Speer 1.130 5.0 975

    I'm sure someone who is way more knowledgable than myself will chime in, but I asked a similar question to a friend who's into IDPA and this was his answer.

    1- Bigger = slower / less recoil / slower follow up shots

    2- Smaller = faster / more recoil / quicker follow up shots

    3- Some kind of sweet spot = perfect lol

    I can't remember his exact logic behind the more recoil / faster follow up shots thing lol.

    As a side note in my personal experience 124gr factory ball S&B, Remi, Winchester, Blazer, Aguila, etc is about the sweet spot for me as far as recoil goes.

    Faster follow up is not a priority... an acceptable recoil for my shooting partner, who has equal say in our gun related $$s is the goal. :rolleyes:

    If I could make a suggestion, choose the lighter bullet (115g). Then select a few powders that are known to work well for your caliber. Make five rounds of each at the minimum powder charge (slowest velocity). Shoot them and pick the one that has the best combination of accuracy/felt recoil. Another suggestion would be to try a lead or coated lead bullet that can be shot at a slower velocity. If you’re shooting a 1911, just keep in mind that to shoot really soft loads, you might have to change springs to cycle the slide properly.
    Happy shooting!

    You sir are a wise man. My wife to enjoys shooting and I must say its a blessing and a curse. Our firearms collection is second to none, but my wallet is continually sad lol.

    There is no simple answer to your question without more information.
    Since you are reloading you should have more than one reloading manual.
    Hopefully one will show pressure along with other data about loads.
    Some faster powders are not suitable for heavier bullets. Signs of over pressure may begin before acceptable velocity is reached.
    Some slower powders are not suitable for lighter bullets. Erratic grouping for one.

    So it is important to be specific about your reloads. Exact powder and charge, bullets, COL, crimp and etc.

    Now back to your question: It is unlikely that the pressure will be the same so the recoil won't be the same. Higher pressure should result in higher felt recoil.

    "an acceptable recoil for my shooting partner, who has equal say in our gun related $$s is the goal." :rolleyes:

    A really wise man develops the load for their partner's specific needs!

    What gun?

    Everyone thinks they are immune to recoil.
    It is cumulative.

    Her two current favorites now are a DW Guardian 9mm & a JEM/Caspian all steel .38 sup. commander size.

    Have you considered switching to a revolver? No action to cycle, so you could conceivably run even lighter loads with no need to modify anything. With the additional upside of a possibly better trigger. Just a though.

    I shot 32 longs through my Sp 101 (327 Federal) last week and it was amazingly light recoiling and accurate. In regards light loads you want the lightest bullet with the lightest, by weight, powder charge.

    Momentum is mass X velocity.../ so if you load a lighter bullet at the lowest velocity in the tables...it may or may not give you less momentum than a heavier bullet -- but it depends on velocity of heavier bullet. Momentum isn't recoil ...but its an easy calculation on what to expect from your load & estimate recoil.

    Looking st some load data ....for 115gr & 147gr in 9mm. ...you may or may not have less recoil with a lighter bullet...( powder charge may be about the same ...)...
    115gr X 1135 fps = 130,525... so a little higher recoil
    147gr X 855 fps = 125,865

    Powder selection will give you different felt recoil...because the burn rate and length of time, at higher pressures, caused by powder burn...affect how the recoil feels.

    In general...faster powders ...reach their peak quickly ...and give less felt recoil. But it may be snappier...

    In general...slower powders..build to pressure over a longer time frame ...and it gives you more felt recoil. It will give you more of a thump ...than a snap..

    I suggest...stay with a light bullet in 9mm .....stay with minimum published loads ...and look at burn rate tables for powder....find a faster powder...a mid range ....and a slower powder...buy a pound of each or find a buddy that uses them and borrow 50 grains ...( make up 5 to 10 rds of each ..to test ). You test them...I think you'll know immediately which she will prefer. Then let her test them. You'll find something...

    A revolver is a fixed action gun ...so its going to give you more felt recoil than a semi-auto. Pick the heaviest gun you have in 9mm as well....weight of gun is a big factor in recoil. Make sure she is using double ear protection....good ear plugs ( molded are best)...then ear muffs on as well...... it helps ! Flash & muzzle blast really affect how a shooter perceives recoil.

    Powder charges identical the felt recoil from the 115gr will be softer than that of the 147gr.

    I also reload for 9mm, 38 Super and 38 special.
    Over the years I settled on one bullet that shoots great in all three, yes all three!

    I reload the Extreme 9mm, 135 grain RNFP .356 dia, in all three. Of course each load is adjusted for the specific task. Faster powder for the 9mm and 38 special (Tight Group) and slower powder for the 38 Sup. (Win Auto Comp) Performance has been completely acceptable.

    I also cast a similar bullet from NOE Molds in .358, sized .357 for the same calibers with the same results. No leading just dirty from the soft lube I use.

    The beauty of reloading allows the benefit of tailoring bullets and loads to meet specific needs.

    His last line nailed it. I do the same across 9mm, 38 Super and Sig 357 though I tend toward a 124-125 RNFP bullet. I have been toying with either switching out all my 45 brass to small primer pocket to further reduce component type/cost, but still have quite a bit of large pistol primers.

    I had, at one point, thought I would just stick to shooting 9mm, 38 Super, Sig 357 and 357 Magnum. But I like 45 ACP too much to let it go completely.
