I think the goal is to pick the ammo you and your gun shoots the best.

For what you carry, yes.
Nothing wrong with “seeing what makes it tick” with practice ammunition.

A lot of good discussion. I should explain that for 45 years I worked in a highly technical field in the laboratory on the fringes of the healthcare profession. The human body being infinitely complex cannot be always 100% anticipated. Our goal was to eliminate all the variables we could possibly eliminate. My mindset is programmed that way not all variables can be anticipated but the ones I can control I have and instinct almost to control.

Match the velocity on your loads for constant practice on pistol rounds.

I’d prefer they share at least the same bullet wt, but during the ammo shortage that simply wasn’t practical.
Things have gotten better now.

I’m about to place an order today for a thousand rounds 9 mm 147 grain 300 rounds 45 ACP and 200 rounds 380 auto. All federal American eagle brands. You may want to check out the prices of my supplier that I have ordered from several times. Free shipping on orders over $125 and I usually see the ammo on my doorstep and 7 to 10 days. The place is called bucking horse Outpost. You can find them on the web. So far they’ve been very good to me.

If a 147 grain jacketed and a 124 grain jacketed 9 mm are both loaded so the muzzle energy is almost identical will the perceived recoil be almost identical? My brain won’t function this morning

I think yes they will be almost identical. But maybe not quite since velocity plays a role in perceived recoil impulse as well, heavier and slower is generally, well, slower, and perceived as softer since it’s spread out over a slightly longer time…but we are splitting hairs here in this specific case

I think the correct formula is velocity times weight. The ammo I’m looking at on sale from my normal supplier.
124 grn x 1090 ftsec =135160
147 grn x 1000. Ftsec=147000
11840 difference. Don’t know if that’s significant.
Only reason I’m considering the 124 is the price is significantly different more so than I can just ignore when I’m looking at ordering a thousand rounds
Mass times velocity gives you momentum, but that isn’t the same as kinetic energy. Energy/kinetic energy is (0.5Xmass)*(velocity squared)
Velocity has a much larger impact on energy and recoil than mass does (as the formula indicates, using the square of velocity)
This is why the hot and fast 125gr .357 mags have more recoil than the 158’s as an example

Thanks!
The rounds I carry for defense are more expensive. If I’m shooting them at the range, it’s probably just to cycle them out so I can replace them with new ammo. I can’t tell a difference between my practice rounds and my defense rounds on a pistol range with paper targets.
Rifle cartridges are a different story, but I haven’t found a way to conceal carry a rifle in my waistband.

In my non-experience, observation only opinion, the only thing of any sameness will be gun in your hand. I can’t tell the difference between 115gr. and 147gn, FMJ or polymer coated ! But I hear the difference from a small indoor range and to an outdoor one. From videos I’ve watched I don’t imagine anything in other environments being the same as training-But it’s the best alternative to actual real, I think. In videos I’ve seen 20 yrs accumulation of dust in the 10 ft. acoustic ceiling cloud a small shop from the gun blast, or people tripping over furniture in a mall with marble floors and columns and 50 ft. ceilings. When it comes time will it be summer or winter, impossible wind or annoying rain? I’ve had adrenaline dumps preparing to confront/apprehend too many shoplifters and I don’t like it. Those experiences were valuable but I can’t imagine a LEO experiencing it daily ! Sorry to ramble. IMHO, the first shot has got to count-I’m gonna train more in 2023.
AIWB, FTW.

Well I’ve got a thousand rounds of Blazer brass 124 grain coming. I’ve shot Blazer brass from time to time not my favorite but it’s okay but it’s $13 a box and I couldn’t pass it up. Also have 300 rounds Federal 45 ACP and 200 rounds Federal 380 to top off my ammo stock.
Now that that’s done it’s time to start reloading again and I have everything I need already in stock for that. Going to set up a ladder test for some 137 grn powder coated 9 mm bullets I picked up locally about a year ago from a place called bayou bullets.

Got a deal on these two weeks ago and made the plunge.
For practice I usually get the 115 gr Blazer but the recent deals were too good to pass up. Did not notice too much difference.

That is funny. I did the exact same thing two weeks ago. Got a great deal from SG Ammo. .26 a round for the Blazer Brass 124gr ball.

I ordered 1k round of 124gr Magtech from SGammo a few day ago. $260 free ship same as Blazer Brass. That’s about the price right now

Lol, roger that. They ship pretty fast too. I like them and Lucky Gunner. Unfortunately, Lucky Gunner is a little steep on shipping. Fast though.

@Nathan57 … I bit on that one too. My defensive round is 147gr, but I couldn’t pass up on the offer on the 124 gr. FMJ.; free shipping over $200 too. Here’s the chuckle … one day after the order shipped, they put 147gr on sale - $10 more per case, but still a good deal. There’s a lesson in here somewhere
