SAFETY INFORMATION
This IMR Handloader's Guide presents revised and updated infor-
mation on the use of IMR powders to reload shotshell, handgun and
rifle ammunition. This Guide is not intended to be a "how to" manual
for reloading, and we strongly recommend that all handloaders
carefully read one or more of the reloading manuals which cover the
subject in detail. This Guide is offered to be used at your own
discretion and risk. Since we have no control over the circum-
stances of use, we assume no liability for the results obtained. And
we guarantee only that our powders meet our manufacturing stan-
dards.
powder type and/or weight and the lead shot weight that you are
loading in a shell. Inspect all reloaded shells to insure that crimp
closely duplicates that of factory loads.
Unfortunately, time and space do not permit publication of loads
utilizing all of the many components available. Loading data utiliz-
ing IMR powders for wads not listed in this Guide may be obtained
by contacting the wad manufacturer.
RIFLE
The rifle data section contains data for most of the popular car-
tridges. The components specified were those that were commer-
cially available to the handloader at the time the tests were per-
formed.
It is possible that changes in components which could affect ballis-
tic performance could occur without our knowledge. The compo-
nents used and specified in all our data were those that were com-
mercially available to the handloader at the time our tests were
conducted. It is the responsibility of the handloader to check each of
his components to insure that they are the same as specified in our
data.
The powder charge weights specified represent loads that devel-
oped Maximum Allowable Chamber Pressures with the test bar-
rels used and components specified, with the exception of loads that
are specified as (C) compressed charges which may represent case
capacity rather than maximum chamber pressure. All tests were
conducted utilizing commercial barrels in a Universal Receiver.
Improper modifications and/or alterations can render any type of
firearm unsafe. All work should be conducted by the manufacturer
or a qualified gunsmith. It is highly recommended that a shooter
have his guns checked periodically by a qualified gunsmith to in-
sure that they are in safe operating condition. Treat all guns as being
loaded and read and practice all the rules of safe gun handling and
shooting.
It is not unusual for reloads assembled with particular components
and fired in the individual reloader's gun to give ballistic results
(particularly chamber pressures) that vary in either direction from
the published data. To compensate for any component and/or gun
combination that would tend to yield pressures in excess of the
published data, it is recommended that the powder charge be re-
duced 10% initially. (This reduction in powder charge weight should
also be made each time that any of the components in the load are
changed.) After firing several loads at the lower powder charge
weight—without ANY evidence of excessive chamber pressure—
the powder charge weight may then be increased in 0.5 grain incre-
ments as accuracy needs and pressure indications permit. The sub-
ject of excessive pressure along with illustrations is included in
most reloading manuals, and should be read before attempting any
reloading.
The future of handloading is dependent upon the safe handling and
storage of powder and primers and the safe use of all ammunition.
In this regard, read and follow the recommendations of the Sporting
Arms and Ammunition Manufacturers' Institute, Inc. as published
in "Properties and Storage of Smokeless Powder." A copy of this
pamphlet is bound into this Handloader's Guide.
SHOTSHELL
The shotshell data section offers a wide selection of target and field
loads. There have been a number of changes and modifications in
shotshell components which make it increasingly important that the
handloader carefully check all of the components being used to
insure that they are the same as shown. If you have reason to ques-
tion any of your components, contact the manufacturer.
Always make certain that you use the correct ammunition in your
rifle.
This data must be used only with IMR Smokeless Powders. Never
use this data for powders that may have similar numerical desig-
nations!
Our goal in developing this shotshell data was to offer a selection of
"factory duplication" loads, specifying the average velocity and cham-
ber pressure of the rounds tested. However, not all factory loads can
be duplicated because the components utilized are not available to
the handloader. All of the ballistics data specified were obtained
using once-fired cases and components available to the handloaders
at the time our tests were performed.
HANDGUN
The handgun section contains loads for the more popular handgun
cartridges utilizing the handloading components commercially avail-
able at the time our tests were conducted. We have also included a
section of handgun data for the T/C Contender in cartridge and
component combinations of particular interest to the metallic sil-
houette shooter. Test components used are specified and these exact
components must be used to achieve a reasonable duplication of the
ballistic data shown.
All of the shotshell data presented were developed using lead shot.
Do not attempt to reload any of the loads listed using steel shot.
Substituting steel shot in any load developed for lead shot could be
very dangerous.
The powder charge weights specified represent loads that devel-
oped Maximum Allowable Chamber Pressures with the test bar-
rels and components used, with the exception of loads that are
specified as (C) compressed charges and therefore may represent
case capacity rather than maximum chamber pressure, and loads
that duplicate factory velocity. All tests were conducted utilizing
commercial barrels in a Universal Receiver.
To obtain a reasonable duplication of the ballistic results listed,
you must reload exactly as shown. Substitution of components
especially primers and/or alteration in powder charge or type of
powder could result in extremely dangerous reloads.
Good, uniform, efficient reloads result only from careful reloading
procedures. Always check powder and shot weights on a reliable
scale, use the exact components specified, seat wads properly and
use only cases that are in good condition. Never leave to chance the
Always practice all of the principals of SAFE RELOADING and enjoy
good shooting.

RELOADING SAFETY
Reloading ammunition is an enjoyable hobby, and can be conducted safely if certain rules are followed:
1. Exercise care and common sense at all times.
2. Don't become distracted when you are handloading.
3. Never load in haste. A careless mistake can be serious.
4. Use equipment as manufacturer recommends.
Never take shortcuts.
5. Store powder in a cool, dry place at all times.
6. Never use a powder unless you are positive of its identity.
7. Never substitute smokeless powder for black powder.
8. Never use IMR powder data for any other powder types
with similar numerical designations.
9. Keep powder away from heat and open flames.
10. Never smoke while handling powder.
11. Keep powder out of reach of children.
12. Don't mix powders.
13. Don't keep more powder in an open container than
you need.
14. Observe all maximum load warnings in handbooks.
15. Work up all new loads starting 10% below the
recommended maximum charge weight.
16. Examine every case before loading to insure it is in good
condition.
17. Watch for indications of high pressures in establishing a
new load.
18. Never use smokeless powder in firearms designed for
black powder.
19. DO NOT use steel shot in any of the shotshell loads listed
in this guide.
20. Use of safety glasses while reloading is recmmended.
21. Clean up any powder spills immediately. Use dust pan and
brush to clean up powder. Dispose of it in accordance
with recommended procedures.
22. Make sure powder container is empty before disposing of
container.
23. Consult suppliers of components if you have any
questions about their use.
24. Check powder charges regularly to insure using proper
powder charge weight.
25. Develop a routine for reloading to guard against mistakes.
NOTE:
• It should be recognized that Auto-Loading Shotguns may not function with some of the Low Chamber
Pressure Loads.
• Several Handgun Calibers show Chamber Pressure in PSI.
• If you use Military Brass for certain Center-Fire Calibers the maximum powder charges should be
lowered from data shown.
• We have included a separate section in the Rifle Data Section that provides recommendations for
various Calibers and Components showing Chamber Pressures in PSI units versus prior data with
CUP units for the Chamber Pressure. There will be additions to this section as the data becomes
available.
