Nice rifles all! Don’t have a MSM, just the standard RM. Mine ended up like John55’s though at 8.25 loaded using the same formula shown over and over in this thread.

I too have noticed that McMillan’s fill weights seem to be increasing - not a fan of it either! I’ve got an edge shell/magnum fill at 40 ounces and a Edge shell/ edge fill that weighs 28 ounces. Liked when ordering an Edge meant somewhere around 22-23 ounces. I will be trying something else going forward like the Pound’r. Feel like the McMillans should have gotten lighter over time, not heavier.

Wherever fellas, I am game for about anything. That's be cool as all get out.

Pretty cool to see all of these Mashburns coming to the surface with this thread.

I'll get a picture of Matt's Mashburn, which looks just about like PF76's, but the bolt is on the correct side whistle

Deciding between a big 7 or a 300 Win Mag.

I know Bob always preferred the big 7.

I still have a pile of 7mm Dakota brass onhand, but that would involve work on the bolt face, etc.

Mashburn or Nosler if I go with a 7mm.

I do have a 7mm Rem Mag I built on a M70 classic edge. Sub 8lbs with a Swaro Z5 3.5-18 in Talley Lightweights. One of my "core 4".

Shoots the 160 Accubond VERY well at 3100, so maybe what I'm looking for is already in the safe.

What load do you use to get 3100?


It's either 66.0 or 68.0 7828SSC, I'd need to check my notes. Shot over my LabRadar chrono.

I'm going to load some 175 Partitions over Retumbo and RL26. Should get 2900+ I would think.

If anyone has a good load, chime in!

If the 175 shoots well with acceptable velocity, the decision may be made for me.


I'd bet if you get 3100 with 160 Accubonds you'll get near 3000 with the 175's. I love my Mashburn but a good 7 Rem Mag sure is easy and alot less money!

Gunner sent these from his 500 yard outting with his Masher and 160 Accubonds.. Hard to hate that!

Hey Thanks big Buddy, shooting dew North into a crazy [12-15 mph and gusting] wind out of the E/SE, dialed a little wind and let her fly, I have to believe a bullet without a cannelure would be easier to steer, hoping one of you guys will correct me if that's wrong.

I've noticed some are giving build specs, here's mine:

Pre-64 M-70 H&H magnum action
Factory trigger slicked to a tic under 2 lbs [zero creep]
8 twist #3 Brux, 25 inches
Pillared and bedded into a McMillan Super Grade stock, standard fill
NF SHV 3-10 standard duplex
S&K bases and rings
Magnum para-cord sling by HillhamHawk right here at the Campfire
Complete build by Redneck, also here at the Campfire

Those bullets were ordered as seconds from SPS, and for fire-forming only, I found the load too accurate at 100 yards to waste and add undue wear to my barrel/throat, guess no too bad for a standard hunting weight rifle/barrel, will certainly work for 500 yard big game hunting.

Great build Gunner.

It is odd the 160 Accubonds went wonky at you at further than 500 though. Be interesting to see what happens at 100 yard increments.

Thank You, Yes, may be something to do with twist/speed or just those goofy winds, do you think the cannelure had any role in the silliness?

I don't believe so, especially if they are holding tight at 500 I can't see them just going nuts at 900. What sorta speed is it sitting at 900? I gotta think your 8 twist has them plenty stabilized.

10-4, still packing around 1885 fps at 900, may have been those crazy winds, you can see all the peppering on the right side of my gong out practicing in 30-40 mph winds, crazy stuff man.

All that said, I bet a 180gr ELD leaving at 3000 fps will shoot like a house of fire at 900.

If I was going to try one, I'd be inclined to try the 180 Scenar myself. I know 30338 on here has done real well with them on elk and he puts up plenty of proof they'll smash stuff pretty hard and man, they aren't picky about shooting excellent. I should grab a box and just load them up and see what happens on the Mashburn. They aren't 180 ELD sorta BC but I think they are .660'ish which aint too bad either.

Nice, Thanks for the hit, and yes, I've seen what scenarshooter has done with the little scenars, same but bigger cant hurt.
