Thread: tikka 7mm Rem Mag load development

I use norma cases, 215 fed primers and ar2225 powder. I've had good luck with these and you'll find many others who use the same although not every one uses norma cases. If using lighter than 160gn projectiles 2217 might be a good powder to try. As far as projectiles go , the 150gn nosler bt is always a good shooter then maybe the 168 berger classic hunter but they aren't cheap or the 160 tmk probably in that order. You'll find a lot of people on here use one of these projectiles. Hornady eldx/m are good if your gun will shoot them but they can be finicky. I'm using the 180 eldm and it shoots ok but I put that down to the reduced velocity compared to the 154's and 162's which I had not much luck with. Imo it's not worth using lighter than 150gn projectiles in the 7mm mag as you lose a lot of bc and there are plenty of other calibers that are more efficient firing those lighter projectiles at similar speeds. Berger has a way of trialing seating depth which could be worth ago. From memory it's 3 rounds loaded at four different seating depths so 12 rounds in all. then see what shoots the best group. That sorts your seating( you can fine tune more between two of their suggested depths later if you want) and then it's trying different powder charges at that depth to fine tune. Lastly get it chronoed so you can set up your ballistic app. Accuracy is always first and speed second. If you can't hit it there's no point missing it with a faster bullet. Both together is ideal but make sure you sacrifice the right one if you have to
