Hi all, a few months ago I converted a 7mm Rem Mag Savage Model 111 (accustock, accutrigger) to 28 Nosler. I got some time today to shoot some reloads, and here are the results if anyone is interested.
To Baseline, I chronographed 160 Grain Nosler Trophy Grade Factory ammo, which had an...
Thanks guys - I'm just getting around to checking this now. Reloder 33 was where I was leaning towards starting myself, and you guys confirmed it.
Truck Driver, yes I can only speak for the Savage but for my Savage Model 111, I rented a reamers and a set of Go/No-go gauges from 4D Reamer...
A few months back I posted about a conversion project I wanted to try, converting a Savage 111 in 7mm Rem Mag to 28 Nosler. Well, the job is done and the rifle conversion is complete. Very happy with the 28 Nosler so far, but have only been shooting factory ammo. About to begin reloading.
My...
It looks like 28 Nosler is actually an easier conversion for me. My rem mag came in and the detachable magazine doesn't give me the room to go any larger than the 28 Nosler in length.
What about the 7mm STW? Performance seems fairly identical to the Mashburn, Nosler makes factory brass for it, its a SAAMI approved case, and I've got book loads for it.... maybe a better place to start as opposed to the Mashburn?
OK, I called Alliant and I called Nosler. Here is a quick summary.
Alliant had some supplemental data that they haven't published yet for the 180 grain partition with Reloder 17. COAL of 2.710 max charge 48.2 grains, gave them 2631fps in a 24" barrel. Nosler tells me they quote their seating...
Chronograph I believe to have been working properly. My father was averaging 2515fps from Winchester 180 grain white box ammo, and a few shots of Remington 180 core lokt was getting us around 2500fps. This is fairly standard velocities for 180 grain factory ammo I believe out of a 22" barrel...
OK, decapped the primers with a RCBS universal decapping die. Primers for all three loadings (47.5, 48.0, 48.5) popped out fairly easily. No real difference noted between 47.5 and 48.5. Primer pockets were a little on the fouled-up side but a quick run through with a primer pocket brush...
I will have to remove the spent primers and try to reprime later tonight or tomorrow when I get home. I see no obvious signs on the brass. Primer indents seem the same as the load before it. Also worth noting is I am still .2 grains below the Alliant stated max for a 180 grain bullet using...
Is there any published load data so I would know I am not over doing it? Once my Savage comes in I can measure the magazine box to see if it could handle the longer Mashburn rounds. If not, then the costs for the conversion would probably start to add up.
Since the Mashburn was brought up.... is it worth it to look into doing this modification for my 7mm Rem mag? From what I'm reading online you can still use factory 7mm Rem mag in it in a pinch when your ammo gets lost in shipping. Opinions? If I could get that 175 partition up over 3000fps...
Thanks. My old man came along to the range and we chronographed his winchester white box 180 grains at 2500fps. I'll take the 180 at 2700 over the 200 at 2425 any day. Very very happy with Reloder 17. I may try some 180 grain accubonds as well at this powder charge.
Now that being said, any...
OK, more results. Got to the range today to shoot the 180 grain partitions with Reloder 17. I didn't go too far because I started to get a heavy bolt. I was probably getting the samy heavy feeling from the 200 grain bullets, but in this case I was already exceeding the FPS expected by both...
Wow, quick load is very different from the data Nosler is using on their website for the 175grain and RL22.

I didn't bother with any of those fancy BDC reticles or the turret system. When adrenaline kicks in and I need to focus on controlling my breathing, the last thing I want to be doing is counting hash marks or twisting a turrent and attempting to count clicks. Just went with the regular firedot...
Thanks for the replies. If its not too much trouble, would someone mind doing a QL for the 175 Grain partition with RL 22 and RL 26? Nosler case, Fed 215 primer, going with the by-the-book OAL? Savage barrel, 1:9.5 twist, 24" length.
6mm Rem, I will probably take the Leupold VX6 2-12x42 off...
Thanks for the replies. I managed to find RL22 nearby, so I will start with that. I will look into 26. With how fast the 175 gr partition says RL22 will send it, it looks to be ballistically equal to the 160 grain partition. If I can get it up to 2970 as the Nosler loading data claims, I'm...
I happened to come across a new 7mm Rem mag rifle at a very good price, and am looking into my options for reloading for it. Based off the information I've read online, I'm thinking my best options as far as velocity with still good accuracy are with Reloder 22 or Reloder 25. The rifle is a...
Interestingly enough, when I seated the bullet deep enough to work in the magazine, I was still having issues getting the bolt to close. A few good whacks on the back of the bolt and playing with the seating depth, I am able to close and lock the bolt (and extract the round) effortlessly at...
