Retumbo!

[Guy M]

I've been using Retumbo for the 25-06 since 2008, and used it a bit for the 300 Remington Ultra Mag as well. Are you using it?

Guy, I just happened to have watched the video earlier and I chuckled when you mentioned the 25-06. I had found a screamer of a load back around the same time period that I put together for an antelope hunt. That one was pushing 100gr Nos BT and it was flat shooting for sure.

I really enjoy the content that Gavin, Travis and yourself are putting on the channel. Great stuff!!!

Just watched the video myself. I used retumbo in a 25-06 with the 115vld's. That load had a MPBR of almost 400yds. It works great in most cartridges that are overbore.

I just wish I could find it these days

Use the hello out of it in many cartridges with heavier for caliber bullets. No not the new rage of extreme heavy for caliber. Ie 180/308, 175/284, 120/257.

I'm starting to use it in my 257 Blackbird and 135gr Berger's.

I have been a dedicated user of Retumbo in my 6.5x284's and 300WM for many years. I get excellent accuracy, temperature stability, low ES and typically an additional 50-100FPS from loads using the faster burning H1000, H4831sc. Case fill is generally at or near 100% before pressure signs develop, and I have found with my 6.5x284's that my barrel life can be 25-50% longer, speculating that the slower burn rate lessens heat/pressure in the throat area. I do like to load fresh rounds at the start of each season, as Retumbo does have the tendency to clump up in loaded cartridges over time which, IMO, may cause occasional velocity spiking(10-30FPS). Of late, I have using the double-based powders(ie. R26,VV5XX), with the heavies like the156 Berger. They also produce excellent accuracy, high/higher velocity, and good ES but it appears that it's at the cost of more rapid throat erosion/shorter barrel life.
On of my 6.5x284's…2011 vs 2021…over 1000 shots, no change in throat.

I've used for years in my 7RM with 168gr Classic Hunter berger.

I bought 9 pounds of Ireco 85, 40+ years ago. Still using it in my 8mm Rem Mag with 250 grain Barnes. Chronographs at 2900 fps and 1" grouping.

We've been using Retumbo for many years in a host of different cartridges. In my 25-06's, it has given the best speed with accuracy for the 110 AB's (3,310fps) and 115 Bergers. In one of my 300RUM's, it produces 3,400fps with 180AB's, and is a very flat and accurate shooter. Many more...........

Same in my RUM. For the light and fast crowd it will push a 165 3600fps and a partition handles it all day long.

I have some, but no reloads with it yet.

 

[highbrow]

I use it in the 243 Winchester with heavy bullets for FClass and 7 RM and 180s. Also works well in the 338 Lapua.

My favorite powder for the Ultra Mags, also use or have used in my 6.5-284 Norma and 300 PRC. I am very lucky to have bought a good supply before things got crazy. Cheers, Jason

Retumbo was the powder I used in my 243 with 105 gr. VLD's.
