7mm-300 Win Mag

[Long Range]

Thanks Broz I may make up a dummy case or two with these measurements and check into the hart barrels. I really think that the 7-300 win mag with the 195 may just be a hammer. It certnly can do it with the 180s. I really didn't want to build a 7 any bigger this looks like just what I was looking for. I have some win brass and can get some Norma brass from a bud for cheap he owes me hopefully this will be as good as your RWS.

Actually I feel you will be fine with WW brass as it has a larger case capacity and that will reduce the pressure in this chambering. Not ure of case volume on the norma but it should be very good brass, especially if it has a similar case volume as WW.

I feel this case is the perfect match for a 7mm. And with the first rifle aproaching 1000 rounds now, it is proving to be the best 7mm chambering I have owned for sure. That rifle is still a tack driver, it has taken 3 yotes in the last week all around 500 yards and fast shooting around livestock. Still a 1/2 moa rifle at 1000 too.

That is good to hear Broz sounds like you can't go wrong with this round. I think that any bigger your just over bore and should step up to a 30 or 338 but that's just my 2 cents.

I'm still waiting on my barrel, but its a 7x300wby .150" throat, no turn. With the neck legth of the weatherby case it should go a 1000 rounds and spit them out faster than a stw, it was to be a 7wsm for a friend, he backed out, so I had this match chamber put in instead, from the data I've collected on here and other sights, people say 32-3300fps with 180 bergers pretty easily. Just a thought.

That's a great round as well but just a bit bigger than I want. I was looking at the 7-300 win mag just for the fact it looks like the barrel may last just a hair longer and the shorter case will let me feed it out of a mag while setting the bullets out.

Backwoods, I have done both the 7 STW and 7mm-300 wby since the 70's and own both now. They are the best you can get in 7mm. Any bigger and you get into to much of a barrel burner and not much gain in velocity. Either of these will outperform the 7mm-300 winchester with no difference in barrel life. So close that how you take care of it makes more difference than the chambering. That is why they have been so popular since the 70's and the 7mm-300 winchester has not been. The 7mm-300 wby and 7mm STW have both held numerous 1000 yard bench records and been top chamberings for that purpose since the 70's. I own seven 7mm-300 wby's and 7mm STW's and no 7mm-300 winchesters. There is a reason for that.

For your 7mm-300 wby you can get remington or nosler 300 wby brass and save money over the 300 wby brand brass.

Hey Long Range, maybe you should have titled this thread as " What is your personal opinion of what you feel is a better round than the 7mm-300 win and how many do you own"
