The 270 is certainly a fine deer cartridge and you could easily take deer out to 400yds with it.
I'd opt for a 7mm Rem mag due to the larger bullet, more powder capacity and more bullet choices available to the hand loader.
I like my 7mm Sendero quite a bit, but but it's not my go-to gun. I'm still working up loads for it. I'm always trying something new.
If you want to build a rifle off of the 98 Mauser that was burned in the fire, you neeed to have it checked by a gunsmith that can check the hardness of the reciever most of the time if a rifle has been in a fire, it is ruined because of temper taken out of the steel by the heat of the fire. You have to have it checked and you need to be truthful with the 'smith. If you build it with out it being checked, you run the risk of a seriously bad accident.
In my other post I was speaking of the 270 Win. I too agree that if I were just going after deer I would go with the 270 Win over the 7mm mag. If great big deer and elk are on your agenda then yes the 7mm mag would be better. I really got flamed once for making this statement but this has been mine and my buddies experience with the 7mm mag on average 90 to 200 pound white tail dear. The 7mm mag is too much gun. Yes it kills deer but they want to run off between 50 & 100 yards before they drop for some reason. I am talking about a lot of deer being shot with one not just 5 or 10. We control hunted a big farm where we had to take 100 deer a year, my buddy for 20 years and I helped him for 13 years. We shot deer with about every factory caliber and a few wildcats from 6mm through 45 cal in a 45-70. The 270 Win. with 130 gr Sierra or Nosler ballistic tips really killed deer in their tracks. With the assorted 140's and 150's they also want to run off a ways before they went down. It really comes down to bullet construction and velocity being right. We found that a bullet that is lightly constructed and will start expanding the moment it hits hide and even fully expands and comes apart but will reach the off side of a deer kills like lightening has struck. With bullets that hold together and expand slowly and will come out the other side often deer want to run off a ways before they go down. There are exceptions to this of corse. The Nosler partitions seem to kill very well because the front part of the bullet expands quickly and most of the time fragments but the rear half keeps on trucking. Over all we found Sierra and Nosler ballistic tips to work in the medium to light weight in most calibers to get-er-done. We both have settled on the 25-06 with Sierra 117 gr bullets at 3000 or so fps for our go to deer killing, drop them on the spot rifles. The 308 to 30-06 with 125 Nosler ballistic tips at 2850 to 3100 fps really drops deer also. Have fun and put the bullet where it is suppose to go and it will be meat on the table even if you have to track it down. I personally like to find then where I shot them.
ben thinking about it why not stay with .06 got great balistics up about 300Y ammo is in every ones basment , gas sataiton and small town store and if you want to blow throught the brush just load in a 185 gr but I use 150 thinking might go to 165 like I said going to get a rifle for me or my son
140 G accubond at 400+ dropped a doe dead, like a rock. didn't have the exact range, just stepped it out. I knew it was a 400 yard shot and my rifle was sighted in for 200 yards so I aimed 12" high and she went down. Did the same for a buck the same year at 300 but I misjudged the distance and took out both his front legs and the bullet just grazed along the bottom of his chest, I felt like a douche. I put him out of his misery asap.
I shoot a 270 win and load a 110gr v max. It works great on everything that i have hunted with it. I have Killed Hogs, Coyote, bobcat, deer, geese, fox, and many other animals with my 270 and it works great. I have taken coyote out to 550 yrds and dropped them in their tracks. I am not sure why it is not considered and good long range round. but i am new to this so thats not saying much.
If I were going to go with a lighter bullet it and longer yardage it would a 270 win or 7mm rem mag. Seeing I already got the .06 going to finish off accurizing it and run with it. Next rifle hu savage or rem? 270 win or 7mm rem mag ? Time will tell! Why not be done with it and get all 8.
