Magpro Powder

Guy M · 2024-11-22T20:21:18-0600

Recently tried some Magpro in my 7mm Rem Mag Winchester Model 70 and also in a 6.5 PRC Bergara. Yes it is temperature sensitive. But... Good results particularly with the 175 grain bullets from the 7mm Rem Mag and the 6.5 PRC loads. Who else is using Magpro and is it working out for you?

Very nice, you should use the cx's so we can see how they perform on an elk

I recently tried MagPro as well because RL22 is an $80 unicorn. I actually found pressure before the listed max load. I've never had that with other powders.
So far I'm happy with speeds. I haven't found accuracy yet. It's new and early in the testing for me though.

I have used Magpro in .257 WBY/145 Black Hole, .300 WSM/215 Berger, and .338 Thor/250 Hornady BTHP, which works well.

6.5WSM and 144gr Berger doing 3200fps
Had a double on pigs at 952yrds with that combo. Also, I've tested it at a 40° change and zero difference in speed, so I dont know how sensitive it is?

I used Magpro for a quick, soft shooting, class load with my 7SS. Nothing spectacular for speed, but I wasn't pushing it. Fantastic accuracy as far as my ranges extend. Eye box on full size IPSC @ 325 yds was easy. Instructor in the class gave me a wind call on a Coyote target @ 400. He missed the call. Ibwas hitting POA/POI. Getting ready to take it on a whitetail hunt over Thanksgiving because I know it will work well.

i haven't tried any yet, buy hoping to get good results in many cartridges (7saum, 6.5prc, 243win, 264wm, 300wm & maybe 270win). if it's sensitive then it's not much of a problem for me as 80%+ of my shooting is between 60 and 100*. other than that those cartridges won't be used in lesser temps.

I'm using it in a 7wsm that I put together. 71 grains behind a 175 eldx. Book shows 2950 for velocity but with that load in my gun it does 3040 and shoots 1/2" with zero pressure signs. Max load is 71.1

Beautiful Rifle Guy. Who did the stock work??? It looks incredible. Please let me know. Lenny

I use MagPro in my 8mm Mag. with Barnes 200 grain and it's both fast and accurate.

When I had a 280, I tried Magpro with a 140TSX and got excellent accuracy and MV's. The load was top end at or near max, and I used a Rem 9 1/2 Magnum primer (due to powder charge and it being a ball powder) with no pressure signs. It was purely a hunting load and used in cooler fall weather, so I didn't fuss too much over temp sensitivity. Wish I kept that gun actually!!

Ltbullken · 2024-11-23T08:27:53-0600

If anyone has tried Magpro in 270 Win, I'd love to hear about it!!

Lenny Foffa · 2024-11-23T08:32:03-0600

Not me !! My pet load is 59.5 Grns of H 4831SC /130 Grn Ballistic tip. Works too well for many years .
