Magpro Powder

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

Yep, same, H4831sc is my go to for a few loads. I use RL23 with a 140 NAB with great results, as well. And found IMR4831 and IMR4350 works well too with different bullets! I've got some Magpro so I'm curious to see how it works for others.

Used it extensively in 300 WSM, great accuracy, velocity and easy to find. Do your load development at or near High temps you will be shooting it at. It is temp sensitive so dont let your ammo sit in hot car, you may get some heavy bolt lifts

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?

Any load data on that 6.5 WSM? Recently picked one of those up!

I have used Magpro for years in a 7mmWSM, with excellent accuracy at maximum velocity. In the summer, I have backed the loads off some, but in the fall and winter never have had to worry about temp effects. I easily get 0.75 MOA with velocities around 3200fps with 160gr Nosler Partitions.

I recently loaded for a fellow range club member, MagPro for his two .270 Win 24" barrels. He wanted 150 gr Ballistic Tips loaded for a lifetime tag hunt because he read an article by a hunter he reveres. We settled on an amount of MagPro that produced a velocity of 3025. He practiced this load up to 535 yards. We used Rem 9 1/2 Magnum primers. He gave me a couple of back strap pieces and some burger. The antelope head is being mounted. He was happy with the terminal performance of the Nosler bullet. He hit only one lung, because of the angle of incidence, but the expansion was impressive and the antelope bleed out in a few bounds.

I have loaded MagPro for my three .270 WSM Browning rifles. I find superior velocity with 150 gr bullets.

Beginning stages of load development in a 300WM with 185 Juggs looked really promising. However now saving the 185's for my F-Class 308 and will next try 208's and 215's in the 300 w-magnum. Will post initial results soon.
Hopes are HIGH !!

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!!

I know how you feel about letting go of a good 280 Remington. I purchased a Remington 700 Mountain Rifle when the model was first introduced ( early mid 80's). Wish I still had that rifle, but I had a small gun shop at the time and somebody wanted it more than I wanted to keep it!
