has any one tried retumbopowder in their mag loads? velocity is increased and cup seems to be greatly lower. i am going to load 100 rounds this weekend and i will get back on monday with my results.
I use Retumbo in my Ultra's 300 & 338 . It has given top velocity in both . It is , as far as I can tell , very temperature insensitive. I can easily drive a 30 cal 180 gr. Partion at 3300 and a 250 338 cal Partion at 3000 . In fact I have to keep throttling back , the 250's were running 3060 in the 338 ultra no sign of presure but I'm sure it was over so I backed down to 3000. I plan on trying it in my 300 win and 7MM Rem mag. Good hunting KH
I have two pounds left that I used to use with my 300RUM's. For some strange reason, it puts out a huge flame. Hodgdon said it might be the coating used. I found RL25 little better with velocity.
I am trying to find someone in the MD area that would want to try it to buy it off me.
Thanks Bigcountry you probably just saved me some money. I have been using RL 25 just like you said, with good results. I was wanting to try some Retumbo, but if it does what you say(which I am sure it does), then I will not waste my time with it.
Where are you at in MD. I hunt in a small town called Orleans, at the foot of Sidling Hill. Or just east of Cumberland. Tom.

Yea, I know where orleans is at. Only bad thing I can say about RL25, is lot to lot variations. Maybe it was the seasons and temp, but it seems I need to adjust for each new pound I buy.
i had really good luck with the powder, i loaded 71, 72, and 73 gr. i had good groups, but it is really hard to measure. 2 grains are.1 on the scale. it defenitaly isnt ball powder that i am used to.
I hate Retumbo.....very inconsistant in two mag calibers.....I lit 1/2 pound and watched the show with a grin on my face......The worst powder I have ever worked with.....I called Hodgdon and they said it was my inexperience to blame.....I told the dude that I had been reloading since 1961 (true) he muttered something and I hung up.
I am not kidding....I had 7mag velocities +- 250'/sec. Aweful stuff. Never again. Imust havehad a bad batch....never again. Regards, Rick.
48th, whatmags were you loading it up with? I too have a .300 Ultra Mag, andretumbo works awesome in it. Withremington brass, fed 215 primer and101 grains of retumbobehind a 180 Nosler Accubond, I get 3400 f/s and 1"-1.5" groups depending upon the day and the shooter (me). I know thatI could get betteraccuracywith different loadsbut I'll wait until my guns gets a makeover for that.
