well, I braved the cold, my bones are definitely getting old. Could feel the chill through me even though it was -3.  My fingers were icicles, and could barely feel the trigger.but after sighting in, I was able to get 1/4 moa at 300 yards, within 1" of the target centre. No blueing on the barrel, but definitely enjoyed the smell of burnt gunpowder. I did not hear birds singing, just the constant ringing. The muzzle brake did its job superbly, and the recoil was reduced to a little better than a .222, or a .243 But... The noise just pierced my ears. Next time out shooting I will remember earplugs.

Muzzle breaks are great for the person shooting, not so great for the guy standing next to you. Had a hunting partner that had a break on his 300 RUM and I had the misfortune of being bedside him spotting his shot a couple times while he shot at game, not nice at all. I was sure my ear drums were damaged on one occasion I am sure they were.

so I chronographed the  7mm rem mag rounds, shot 2x 3 rounds for each. 145grn Barnes LRX, IMR 4350, @ 64,65,66 and 120grn Barnes TTSX @ 70, 72 grains  of RL-22. . The speed was not too bad for the 145, 3070 fps @ 64 gns, 3350 @65 gns, and 3440@ 66gns. I was really impressed with the 120 grn @ 70, 72.  Chrono failed on the 70 grn, but it reached 3860fps on the 72grains load.  All measured @ 5 yards. The backstop was thoroughly devasted by the 120, Will try longer distances to determine damage @ 500+ yds. But not Today, too damn COLD

Hi Phoenix ... i have had a 7mm Mag for years too .. and like the heavier grain bullet (PP) in 175 .. its a bit of over kill but with shot placement damage is minimal .. also i have a disc that is rated for my 175gr bullet on my BDC scope .. with the speed of 2860 fps those 4 to 700yds you get those bang flop ....
for those over 700 ..i have had 1 bullet that didn't mushroom down through neck into top lung and held up on skin on a Bull Moose(975yds) went 100 yds off mill cut .. shot up close finished him .. on a Mule Deer(1200) buck hit neck bone & dropped in tracks bullet expansion was instant .. on another Mule Deer buck(765) waited the hour then harvested as i lost sight of him .. the wound channel was as expected just back a bit (lost liver) .. in the mountains with wind being a factor i like the heavier grain bullet and have used only 175's for over 30 years .. i also belong to LRH group forum ..if you ask there you will get some more opinions  ,,  https://www.longrangehunting.com/forums/

Food for thought

Thank you, David,
someone on another forum told me that the higher speeds were better to handle wind. IDK???? My first Howa 7mm rem mag hated the 175(?) Bergers. I could not pattern at 100 yards, and it got worse when I went higher in weight. I went to the Marksmen in Lethbridge, where I was clued into lower weights. Started loading lower and lower and got better groups.  But I will reconsider higher weights again if I can get them to pattern.

My thoughts are simple because I'm simple. Take 3 different sized rocks. Throw the lightest one. Doesn't go very far and there's not much action on the other end. Now take the medium rock. You throw it farther and there is a satisfactory result at the other end. Take the bigger heavier rock and once again it doesn't go very far but man does it put  a dent in things. I think you got my point.

I shoot Barnes in pretty much everything but my 25'06. In my 338 I use 185 gr ttsx  lighter then what I probably should use but the way I understand with Barnes is they like speed. They need the speed to properly do their expansion thing. I've also heard that the energy released of a lighter grain Barnes is equal to a heavier cup and core.  I've only recovered on bullet out of multiple animals. This includes elk and Yukon Alaskan moose. I'd rather not recover the bullet and recover the animal any time.
