7MM build to "do it all"

[Bustercluck]

Thank you for taking the time, appreciate it. That's the weight I would like to be and very good point about the chassis and weights option!

Personally, I’d be looking at something about 3 pounds heavier. It would probably look like a McMillan tactical stock, full weight action and something similar to a 5 or 6 benchmark at 26” with a little bastard break.

The good thing about custom stuff is if you dont like it you can change it. At the end of the day a barrel isn’t a huge deal to get changed. Also why chassis are nice, you don’t have to worry about opening up a barrel channel or getting the same profile.

Tikka T3X Ember 7 RMag rebarreled with a Benchmark #2 Fluted 24 “ . Total weight 116 oz ready to shoot . RJ

that's a hair over 4pounds..... how is that possible?
and how is your shoulder shooting such a light rifle in a 7rm? hhehe

mine is 9lbs 6 ounces unloaded
Ruger M77 MkII 7mm rem mag , gone over by Joseph Dlask some years ago. It has been a very accurate rifle

Something has changed or my calculator has screwed up - 116 ounces divided by 16 ounces per pound is 7.25 pounds? "Ready to shoot" implies some ammo on board - one, two, three, four or five rounds? If no ammo, then that would be rifle, bases/rings as required, scope, carry sling.

nice one RJ , where did you find the Ember?
edit- I see its a rebarrel

LOL you are right..... I dunno what i did with my calculator when I computed that math but I obviously messed up .
Thankyou for the correction and that number makes a whole lot more sense

I have a 7 saum, got it back from the gunsmith in November 2022. Only have shot it a few times at the range, since then, life if far too busy. Think its going out for a few walks this November.

Kind of wish I had a 7 PRC for good factory availability, but for out to 500 yards hunting its more than enough. Little less recoil then the PRC too.

Thanks for all the replies and time you have all spent, I appreciate it! Been reading every reply. I've decided a couple of things.

Action will be a ks arms/ really like Tikka but ks it will be
Barrel will be ks arms in 7prc, not sure on profile yet? Brake will be ks arms
Trigger will most likely be a trigger tech diamond or special

As for stock, I am not sure yet. Thinking of an AG or the MDT CRBN, thinking this will end up being an all Canadian components build! Are there any oher Canadian stock builders besides MDT?

Great choice on KS Arms. They built me a barrelled action chambered in 300 PRC that shoots incredible. I wasn’t aiming for lightweight in that chambering and intended use so chose a 3 lug standard weight action and a 28” barrel, little over a med Palma contour and not fluted, MBM 4 port brake, triggertech special. It’s in a KRG Bravo stock and Zeiss V4 6-24. It sits at 13.5 pounds and I’ll add some weight in the rear of the stock.

I do also have a Wildcat KS Tac Hunter stock and Hawkins Precision Hunter DBM that I may try out on this rifle.

There seems to be quite a bit of videos on the 280AI from youtubers lately. Ron Spomer is a huge 280 AI fan, backfire has also released a few videos recently. It looks like the 280AI might be making a comeback.

For a hunting rig only...I would 100% go with a 280AI.

The 280 AI's biggest downfall is brass availability/brands. Nosler brass SUCKS and is EXTREMELY expensive (And nobody will change my mind, when you get 1 firing from a 300 RUM running a mild load of H1000 and 180gr TTSX, you'll understand)

Peterson is really your only option I believe.

When it comes to precision shooting, i'm basically at the point that if I cant shoot Lapua or ADG brass, I wont have it in my safe. When it comes to hunting its a little different. Like in my 270 WSM federal is just fine, but i'm not picky on ES/SD with it cause it doesnt matter at 400 yards. But if your wanting a rifle to do both, you'll want quality components to load with OR have the option for precision factory ammo and lots of it.

Well I caved today and brought home a new X-Bolt ODG Green Synthetic Hunter in 7 PRC and topped it with a Veracity PH 4-20x50. Im looking forward to seeing what all the hype is about. Its got a 24" barrel so I dont think itll be a speed demon by any stretch but i'll take it to the range and chronograph the factory 175gr Precision hunters tomorrow when I sight it in and test the accuracy.

Ths Nosler is CRAP for sure - so is Hornady - The PETERSEN is Excellent ! The P pockets are tight after 3 HOT loads ! jmo RJ

I'm looking forward to it. I wanted something larger than a 6.5 as my 257 wby mag is a laser beam and hits hard. But I didnt want to go to a 30 cal+ so I figured this fits the bill nicely for longer range hunting or elk hunting. Ill take my 257 moose hunting all day

Little Range update from the new x-bolt 7 PRC.

Using factory Hornady Precision hunter 175 ELD-X it shot sub moa, 3/4" at 100. Nice. However im a little disappointed with Hornady and the in-consistancy with their ammo. I bought 3 boxes of shells yesterday when I bought the rifle. All 3 different lot #'s. 2 boxes of shells had silver primers, one box had gold. After I zero'd the rifle and did barrel break in is when I noticed this, and I zero'd with the silver primed ammo. When doing the velocity tests, I wanted to see if there was a difference between the 2 types of ammo.

The silver primers were 2830 fps avg with a fairly low SD/ES (20fps ish)
The gold primers were 2930 fps avg with also a fairly low ES/SD.

Keep in mind the box advertises 3000fps. 50fps +/- is fine, but 170fps +/- is a little much.

So now, I zero'd with silver primers, and not sure if the gold primers will have a different POI as I didn't want to keep burning ammo as Im 2 hours away from more and my rifle season starts in a week, but even if its 1/4" higher, I think it will be okay (I will be reloading in the future) and I will use the rest of the silver primers first as thats what Im zero'd for, but when im out of them I will have to confirm zero, or re-zero with the gold primers and change my dope as 100 fps with a long range rig is quite the difference. In fact the 100 fps difference between the 2 velocities @ 700 yards is 9", thats the difference between a fatal hit and non fatal or even miss on a deer.

I called Hornady on the way home from the range to tell them this and the guy was very nice but didn't really say much other than "ya different lot #'s will have different results" which I understand but to have 2 different kinds primers and have that much variation between the 2 is substantial and for a company that advertises this "precision" ammo, thats not my definition of precise thats for sure.

I guess you missed the hububb earlier this year. Shooters realized the hard way that Hornady swapped the content and performance of their factory 7PRC ammo without changing the labelling. As you found out, they made it 100 fps slower.

 

[Potashminer]

Is not as if marketer has ever exaggerated the velocity on an ammunition package - go back to early 1960's when 7 mm Rem Mag was introduced to "beat" the 7x61 Sharpe and Hart cartridge - then Norma changed their brass to become 7x61 Super - very few private people had a chronograph to compare result from 26" barrel in Schultz and Larson rifle to 24" barrel in Remington rifle - I believe most all people were going by the numbers in the advertising - there was really no other source of information for most people. You will see velocities given from 26" or 28" barrels, yet no common commercial guns made with barrels that long, yet "speed" "sells".

I am willing to bet that Hornady did not make changes, other than changing the sub-contractor that supplied that ammo, that was then sold with a Hornady head stamp in a package with the Hornady brand and logo on it.
