Re: New caliber for first build?

Curious, I am looking at deciding to go with the 7wsm or sticking with the 7mmRM I have now when customizing a Sako 75 I have, which will also be my first custom build.

For me the 7mm 168 and 180 bergers shine over 600 yards. My current gun shoots the 168 at 2975, which is well over 1500fp of energy at 800 yards with very little win drift. To go to a 300 magnum in wsm wm or wby, you will see your recoil go up by 25% or more on 180 grain bullets, that will not match the long range ballistics of the 7mm berger.

If you prefer, say the TSX, which is usually accurate and penetrates much deeper, though doesn't kill better in my opinion, then stepping up to a big 30 would make sense as you have much poorer long range ballistics with that bullet and need to compensate with powder and recoil.

For me the decision is actually between the 7mm RM, 7wsm, and 7saum!

If the 7RM is already accurate, why mess with it? What twist is your 7RM and have you tried the 180gr Bergers?

Recoil for a custom LRH rifle in 300WM or bigger anything should not be a major concern as you will surely have a heavier barrel and muzzle brake.

Re: New caliber for first build?

Richard,

Accuracy has become the problem. It varies between .5 and 1.2 moa. In particular I notice it grouping in two groups. I have put about 750 rds down the barrel already so I don't want to waste a bunch of time fiddling to find the problem. I want a gun I can rely on. I love to shoot, but my only MAIN concern is consistency for a hunt. I know the lead time to cusomize is long, so I am planning to just go custom. Right now, like this pos author, I want to take what has been my 600-650 yard comfort zone out to about 800 and start practicing more out to 1000 on paper. I do love the statistics the bergers give at 3000fps or so out to 1000 yards for deer/elk. I have killed 2 mule deer buck and 2 elk with these bullets out to 400 yards so far with very favorable terminal performance(death). No more than two steps.

Anything 7mm that will drive the 180's over 3200.

The 7mm practical might, but the 7 stw, 7 allen mag, or any other lapua based 7mm would be perfect.

338 will still win in the wind, but you wont be far behind, and 800 yards isn't far at all for a 180 vld.

I know its easy to get attached to a brand, but a rem 700 is seriously the best bet for this.

7 WSM is a good round, but if youv'e got the length and your going custom, dont settle for second best

Chris

Re: New caliber for first build?

Well here goes the ******* contest, when a 26" barreled 7mm rem mag will drive a 180 berger at 3-3100fps with retumbo or H1000 why use anything from a 7mm practical up to a 7mm rum or 7.21 lazzeroni and gain 100-250fps, use a lot more powder, and be putting a new barrel on 4 times faster. 7mm rem mag 180 3050 vs 7mm STW 180 3200, now do tou think a deer will notice that difference at 800yrds, no, if your aim is on it'll still be dead either way!
