Bugling Bull Game Calls

Rockie Jacobsen has owned Rocky Mountain Hunting Calls and Supplies (formerly Bugling Bull Game Calls) since 1993. He and his son, Corey Jacobsen, along with Steve Chappell and Kristy Titus team up to produce some of the most versatile and realistic sounding calls on the market. These folks are public land hunters and know how to make calls to pull in pressured elk.

All of the Bugling Bull Game Calls are now available below with free U.S. shipping for orders $50 or more, or a flat rate of $5 for under $50.

Rockie is a three-time RMEF World Champion elk caller. He invented the Palate Plate design, which Primos uses on their calls. He is co-host of Explorer’s Big Game Journal TV Show 

Corey is a four-time World Champion elk caller. He won the new Champion of Champions division in 2013, barely edging out Rockie in two different tie breakers. He has finished in the top 5 in the Professional Division at the RMEF World Championship Elk Calling contest over a dozen times times.

Steve Chappell has been an elk hunting guide for over 20 years. He has a hunting TV show and has collaborated with Rocky Mountain Hunting Calls since 2010 to develop the Signature Series line of custom elk calls.

Kristy Titus is a published writer for several publications and has hosted and appeared on multiple outdoor television shows.

We have put together a money-saving combination package of Bugling Bull Game Calls and ElkNut's elk calling instructional productions. Click here for more information found on the ElkNut page.

Bugling Bull Game Calls

Bugles/Grunt Tubes:

Select-A-Bull Calling System

The Select-A-Bull Calling System has the Bugling Bull Game Calls Conqueror mouthpiece on it that allows the use of teeth on a rubber flap, instead of your tongue or lip, to vary the pressure to make the varied notes of elk sounds. (You can also just use a mouth diaphragm call with all of their tubes.)

The Select-A-Bull also incorporates the Tone Selector to "dial" small, medium, or large bull sounds, as desired. It has a quiet, extendable inside tube to provide for compaction to make it easier to carry. Rockie's patented "Tube Tamer" (on the Select-A-Bull and Bully Bull Grunt Tube) is a rubber vibration damper that helps to eliminate unnatural resonance from the plastic grunt tube.


The NEW Bully Bull ‘Extreme’ Grunt Tube is designed for use with diaphragm calls. With a new, larger diameter mouth-opening and tapered venturi design, you can put your lips inside the mouth-opening more easily. The Bully Bull ‘Extreme’ still creates consistent airflow with ideal back pressure for easier to obtain octave changes. (It does not include include the Tone Selector, but does have the same Tube Tamer described above.) The rest of the tube, besides the mouth-opening, is the same size as the Bully Bull above. Designed by world champion elk callers Corey Jacobsen and Rockie Jacobsen.


The Pack-A-Bull System is a smaller Bugling Bull Game Calls tube made with the Conqueror external mouthpiece. The diameter of the tube is not as big and "throaty" as the other two, or as long, but is made for reduced bulk.


Wapiti Whacker

In the Professional Series, the "Wapiti Whacker" will create all the sounds, even the high pitch screaming challenge, location and display calls of a bull elk. With all of these innovative ideas all wrapped up in one unit, you can now expect the accuracy, realism and ease of use in this Bugle Tube. The most realistic sounding elk grunt tube ever! For use with your favorite mouth diaphragm call.

Mouth opening: 1” / Length: 20”


Wild Frenzy

The "Wild Frenzy" Bugle Tube from Rocky Mountain Calls is a Rockie Jacobsen and Kristy Titus creation. It delivers both the volume and raspy sounds that allow you throw down a challenge to big bulls when the heat is on during the rut. It has the Tone Selector at the end of the tube that gives you the ability to change the volume and control the back pressure on your diaphragm. The Volume Enhanced Tone Technology (V.E.T.T.) system allows you to produce exceptional volume, consistent high notes, raspy growls and smooth octave changes – all with minimal air pressure. The Tube Tamer is a vibration dampener on the inside of the large end of the tube, which eliminates plastic "tuby" sounds. 

Mouth Opening 1"

Length 18"


Hand-held Reed Calls:

The Temptress Elk Call

Designed by Rockie Jacobsen, the “Temptress” utilizes the innovative “Tone Cap”. This cow call was used by the winners of the Professional, Men’s & Women’s Division at the 2011 RMEF Elk Calling Championships.

The most realistic cow call ever for no-stick response every time.
To use, simply place your top lip over the reed, positioning your lip against the “Tone Cap”. Softly blow air over the reed to obtain sweet cow/calf mews. Firmer lip pressure creates higher pitches, while less lip pressure results in deeper pitches. The squeezable end cap , as well as the holes in the “Tone Cap”, can be used to change the tone, pitch, and volume of the call.


Trophy Wife 2020

The "Trophy Wife" is part of the Steve Chappell Signature Series. is made to produce the nasally, estrus sounds, but will produce all cow/calf mews. It can also produce and imitate the estrus scream. The Trophy Wife is easy to blow and sensitive. Simply use your top lip on the reed and blow air across the reed. Firmer lip pressure creates higher pitches, while less lip pressure results in deeper pitches.

Cow mews start with a high pitch and taper smoothly to a lower pitch. Mews should be about 1 second in length. Chirps are shorter and higher pitched, lasting less than a second. Estrus mews are pleading and drawn out to 1½ seconds or longer. Practice on the call and listen to real elk on ElkNut's CDs and DVDs, since they are the best teachers of all! 



The "On Fire" is a medium sized acrylic cow call has a smaller sound board and barrel. The narrow v-notched reed creates soft nasal mews, chirps and great estrus whines. It is in the Rockie Jacobsen Series. 


Voo Doo

From the Professional Series, the "Voo Doo" cow call was designed to put a spell on the majestic bull elk. With its unique sound board of vented holes and tone quality acrylic barrel, this call will produce realism, accuracy and ease of use in elk call sounds. With its pleading estrus sounds, easy to obtain mews and chirps of both cows and calves will make the Voo Doo hard to beat for calling in your next elk.



The "Seducer" has a polished black acrylic barrel with the RMEF logo engraved on it. The sound board has 2 holes that create very mellow sounds. The combination of acrylic barrel, sound board and reed produce very clear notes of cow and calf mews and chirps. The Seducer will also make great estrus sounds. Lanyard included.


Heart Breaker

Built under the Steve Chappell signature series line, the "Heart Breaker" has a wide reed, wide sound board and lip positioning ring. The Heart Breaker can produce all cow/ calf mews and nasally estrus sounds as well as the estrus scream.
