factory ammo vs handloads: two rifle cartridges standing side by side on a range bench

Every handloader eventually hears the question: is your ammunition actually better than a box off the shelf? Factory ammo vs handloads is one of the most argued comparisons in precision shooting, and most of the arguing is done on the strength of a single group fired on a single afternoon. A fair answer needs the same discipline you would give any load test: one rifle, one day, enough shots, and an honest reading of the spread. This article lays out how to run that comparison without fooling yourself.

Why the usual factory ammo vs handloads test is unfair

The typical comparison goes like this. Shoot a five-shot group of factory match ammunition, shoot a five-shot group of your handloads a week later, and pick the smaller one. Almost everything about that is stacked. The rifle was warmer or colder, the wind was different, your fouling state differed, and five shots is far too few to separate two loads that are close. Nothing has been learned.

Set up a factory ammo vs handloads test so only the ammunition changes

  • Same rifle, same day. Optics, rest, barrel temperature and light all drift through a session. Do both loads in one sitting.
  • Interleave the strings. Fire a string of factory, then a string of handloads, then factory again. If the barrel heats or the wind shifts, both loads feel it. Shooting all of one and then all of the other bakes the drift into one side.
  • Same target and distance. Use the same aiming point style and the same range for every string.
  • Chronograph every shot. Velocity spread tells you things the target hides, and it takes no extra barrel life.
  • Enough shots. More on this below, because it is the part most people skip.

A cold bore adds noise, and our piece on cold bore shift explains why a single first shot proves little.

How many shots you really need

Small samples mislead in both directions. A three-shot group can make two identical loads look different, and it can hide a real difference just as easily. The statistics behind that are covered in how many shots for load development, and they apply with full force to a head-to-head. If the two loads are close, you will need many strings pooled together before a gap means anything. If one is clearly worse, you will see it sooner.

Grade the target with a measure that uses every hole. Extreme spread rests on two shots, so it is jumpy. Mean radius uses all of them and settles faster, which suits a comparison built from several short strings. In any factory ammo vs handloads test, treat a single group as a hint, never a verdict.

Read the velocity numbers honestly

The comparison only works if you compute SD the same way for both, as population SD, with the same rules about flyers. If you want a benchmark for what the numbers mean, read what is a good SD for reloading first. A ten-shot SD is an estimate, not a fixed property of the ammunition, so two values a few fps apart are not evidence of a winner.

Expect lot-to-lot variation in factory ammo as well. A box bought this month may come from a different production lot than the box you tested last season. Velocity and grouping can shift between lots, so record the lot number and treat a new lot as a new load until your own data says otherwise. For industry standards and background on ammunition, SAAMI is the authoritative source.

The real cost per round

Cost is the other half of factory ammo vs handloads, and it is easy to get wrong. Factory match ammunition has a clear price: box price divided by rounds per box. Handloads are murkier. You pay for powder, primers and bullets by the round, brass is spread across its firings, and your time and equipment are real costs even though they never show on a receipt.

Compare like with like. Count the components you actually consumed, spread brass over the number of times you expect to reload it, and decide honestly whether your bench hours belong in the sum. The longer discussion is in is reloading worth it, and the saving is often smaller than people assume.

When factory is the right answer

Choosing factory is not a failure. It is sensible in some situations.

  • A new rifle. A box of match ammunition gives you a baseline for what the rifle does before you change anything. If it shoots well on factory, you have a reference point for every handload that follows.
  • Time. If shooting hours are scarce, spending them at the bench is a trade, not a given.

Where you do reload, always follow current published manufacturer data for your components. A factory ammo vs handloads comparison never tells you what to load.

Running the comparison in LoadNode

LoadNode 2.0 puts both sides of a factory ammo vs handloads test in the same logbook. You can switch a recipe from Handload to Factory ammo and record the product, the maker, the bullet and the lot number, plus an optional box price, rounds per box and currency. That is free. Factory loads are marked as factory everywhere they appear and never draw components from your inventory.

For the shooting itself, use the Group test session type: strings of one load with no ladder. Pick a factory load and the session becomes a group test automatically. Tap Add string for each string and log your shots; that is free. Group Analysis, a Pro feature, pools the strings into one group and compares them. Compare loads, also Pro, sets two whole loads side by side, each with a confidence interval, and it does not declare a winner. A small sample gives a wide interval, so it shows when the data cannot separate the two yet.

With box pricing, a Pro feature, LoadNode works out cost per round, per 100 and per session. On the Costs screen, factory loads are compared per round with your handloads and kept out of your handloading spend, so the two do not blur together. LoadNode is local-first, needs no account, and never tells you what to load. It keeps the numbers straight so the comparison is yours to read. The Free vs Pro table lists what each tier includes.

Handloading is an adult activity done at your own risk. LoadNode is a logbook and analysis tool: it never provides load data. Always develop loads from current published manufacturer data and work up safely.
