Thread: 7mm vs 300 in Blaser.

Hey all, getting close to procuring a new barrel and would like some feedback on the above two calibre choices. I have a good idea of projectile choices for the 7mm and have also been considering the 300 Blaser Magnum as I have always liked the 30 caliber pills on animals and amax is obviously still an option for both choices along with the Bergers, Barnes etc. plenty to choose from.
Recoil is not an issue as I have a pussy cat barrel for the son to use later on and I'll get another can or a T2 for this thing.

I'll be shooting steel and animals and have no doubt both fit well, I have been told the 7BM is more popular but I haven't heard anything of them especially on here...the 300 there is some decent feedback especially with accuracy which is the main thing for me.

I was going to go 7Brenneke but there isn't quite the jump from my current caliber to warrant such an outlay.

If there are any out there who could chime in with some thoughts please do so.

Hi I run a 7mm rem mag (similar to the the blaser 7mm) in my R8 and a 300 blaser mag. They are both excellent. The accuracy of the 7mm with Eldx 162 or hunter VLD is .25moa . Recoil is very manageable with my rifle which runs an MAE suppressor and night force. Only down side is the 9.5 twist doesn't really allow you to use the 175 or 180gr bullets well.
I've just developed a .5 moa load for the 300 using 178eldx. I'm working on bringing this down to .25 . Definitely more recoil. But handily the Trajectory is effectively the same as the 7mm out past 300m . Just uses more powder 80gr vs 69 of 2217.
Ive both but you can go wrong with either. Nothing I've shot with the 7mm has gone more than 10 seconds. Nor have I missed a shot in varying conditions over the past 2 years. I expect the 300 will be exactly the same with a fraction more recoil. Remember to get really slippery 300 rounds you are looking at 200+ grains. That's a LOT is bullet with all the other consequences. By the way all my barrels are semi weight and I think suits the magnums. Down side is rifle feels heavy after a day in the bush. But worth it when you get presented with a cross valley shot and you have the utter confidence if you can see it you can shoot it.

@Danny PM me your number, can give you a call and talk about what I've found with my .300 Blaser, damn accurate actually... The barrel and work was all done by Hugh Bradley at Stager/Bradley Barrels.

This is factory Norma with 200g Oryx at 100m, load development with a better BC projectile could be better.

Interim load development. 5 shots 100m I pulled the top one. Definitely can do better based on my experience of the rifle and blaser barrels.
