7mm rem mag to practical

hi shooters/hunters.
iv been away for a while. my 7mmrem mag sendero. has lost its accuracy the throat is a bit cracked and needs a new barrel.
so the obvious let's go to a practical... or should we is today's question.. .
I really like my rem mag. always shot the 162 a max. and am happy with recoil and performance. I have dies etc. and I think about 1000 a max. so that's what I will shoot.
am I missing out not going to the practical?
I have no issue will the rem mag performance. I don't think I'm missing that much not shooting a more heavy projectile. and iv got too many a max now.
so talk me out of the rem mag....
out of interest how fast is the 162 in the practical?

Re: 7mm rem mag to practical
You'll be looking at 3150 - 3250 with 162s and 3000 - 3100 with 180 ELD-M depending on barrel characteristics

"I really like my rem mag. always shot the 162 a max. and am happy with recoil and performance. I have dies etc."

Is the change needed or simply wanted?
Have you looked into the cost of setting up & running a Practical against staying with another 7RM.
You are not using the 7RM's full potential so is that something you'll likely do in the future?

Re: 7mm rem mag to practical
I'm not sure why you think I'm not using the rem mags full potential?
Because I'm only using 162?
162 was about the best given the twist and more heavy were not really around when I started loading for it.
Obviously I can choose a faster twist now. But the 162 has worked well in the past, I'm not sure a 180 will be that much better.
Mine shot 162 at about 3050- 3100.
I'm not sure the change is either needed or wanted, but originally it was the plan to re-barrel to the practical. I'm just wondering am I missing anything if I don't....
Barrel life, case life, inherit accuracy?
No doubt more recoil, but maybe not too noticable, I'm not sure.
Maybe an easy 3150 with the 162 is better than a maxed out 3100, I don't really know.
Just weighing it up.

Re: 7mm rem mag to practical
If you were happy with your 7mm Rem Mag, then why not go with replacing the worn barrel in the same caliber? I assume this to be your all-round rifle for hunting, and have been more than pleased with mine.

I see the attraction of the 7mm Practical for those who tend to make most of their shots at very long ranges, and since if I want to do that once in awhile I can - but choose to stalk closer most times. Doubt that I need more and if I do then it is likely to be a 375 h&h fof something nasty.

Re: 7mm rem mag to practical
Yep that was what l was trying to say looking at it from an extended range view. You are not running the heaviest, highest bc pills on game or target & also not reporting the need for more energy.
So do you need the extra case capacity?

My understanding of Nathans design intent for the Practical was to extend the effective range of the heavier 7mm pills to take advantage of the high BC's whilst delivering high amounts of energy on game.
If used as a combination/general use type set up, hunting, pinging gongs, rocks or targets the extra barrel life of a slightly smaller case would be my preferred option.

Re: 7mm rem mag to practical
Yes open ground hunting. Mostly 6-700 yards or less. I did use mine at a full bore range a bit too. But I feel other than some checking and practice it's not ideal.
I guess round count is subjective... When do you consider the grouping too big. Without looking at my book I think I was at about 1000 rounds.
It's exactly what I'm thinking , stay with the rem mag. In saying that I haven't really looked into the 180's I just figured I got on fine with 162. Any more advantage would come at a cost, money and recoil. And does the bc out way it.

Re: 7mm rem mag to practical
I can share my personal take on this question. I am having a Sendero 7mm RemMag blueprinted and reamed out to 7mm Practical. Why? Because I wanted to. It’s new to me and I’m interested in pushing beyond what I know, which is why LR Hunting is interesting to me, it pleases me to try.

Isn’t that why most people are on this forum? personal ambition and intellectual challenge? The technical means may be practical, but the desire to LRH is aesthetic.

If you’re looking for purely pragmatic pursuits, there is nothing more mundane than picking up a pot-roast on your way home from work.

I see a 7mm Practical as a rare possession. On the other hand, I can pick up 7mm RemMag at most any GShop, anytime. I recently bought a stainless Winchester Model 70 Classic in that caliber for $225 USD.

Re: 7mm rem mag to practical
Okay, John. When we do eventually meet I expect some tutelage on how you locate Winchester 70s for that price.

Pawn shops and dickering, particularly if you see they have a wall full of rifles just sitting there.

Re: 7mm rem mag to practical
Hi Jason, my apologies for the late reply, the cyclone knocked out our power and put us behind.

You could if you want to, have your current barrel reamed to 7mm Practical if it can be centered nicely. You would need to price up the cost of reaming, recrowning, new brass and new dies to see how this fits with your budget. But do keep in mind that sometimes, the steel at the chamber can become quite hard. If the reamer is struggling to cut, it can be better to start over with a fresh barrel rather than both chip the reamer and gall the chamber. It can however be worth a try.

There are some good pros and cons within this thread.

There is some inherent accuracy in the Practical design due to the neck and throat dimensions.

Re: 7mm rem mag to practical
No worries Nathan, it looked the Strom would be giving you grief.
I like inherit accuracy.
My throat looked fairly cracked last time I scooped it. In saying that maybe it's not as bad as it seems, In reality. But if I'm going there I think I would like a new barrel.
Any thoughts on the difference in recoil with say 162 in the practical vs rem mag? Not a lot?

Re: 7mm rem mag to practical
Hi Jason, there is a step up in recoil. Felt recoil is fine in a suitable platform such as yours. But the recoil can effect accuracy if one does not pay close attention to technique. Recoil is of course a very subjective issue depending on rifle dimensions (including barrel contour), our health, fitness and methods. I spoke to a lady who used her husband's M700 practical yesterday to drop a porker pig, seemed happy enough with the recoil but it was just one shot. Steph has used my rifle here and there, comes home with a load of meat without complaints but she does talk about the importance of technique when relaying her day in the hills. Her own rifle is a 7mm Rem Mag, a couple of pounds lighter than the Practical which translates into pretty much the same level of recoil.

Like anything, practice is the key. Most folk can get down to 1 MOA, but it takes dedication to get a high recoiler down into the sub half minute region. If you are not getting out much, the Rem Mag can prove easier to work with.

I am not a fan of putting add ons onto the Practical to tame recoil unless the shooter has an injury etc. The risk of a swollen muzzle is just too high (specifically with all of the half inch threaded rubbish floating about). Another forum member is just going through this reality now with his 7mm Practical.

In any case, I think it is worth considering what both Marty and Bryan have said. The Practical really comes into its own way out long (well past 700 yards etc) and with heavy pills. I do however have a feeling that we can expect more heavy offerings from either Hornady or Sierra over the coming years.

Re: 7mm rem mag to practical
With the excellent heavy 7mm projectiles now available & as you say Nathan "possibly more to be offered" it really has opened up the roles & ranges the Practical can be put in.

Will have to make a tough call when the 300wm runs its barrel out, a big, wind cheating slippery 7 would be a big plus in the hills!

Re: 7mm rem mag to practical
Well thanks everyone for opinions and replies, I feel well informed its really up to me now.

My thoughts are, I don't have a problem with recoil with the rem mag. It's performance I do like. I believe in performance yes, but bigger isn't always better because of recoil, if recoil is more manageable it leads to being more accurate more often, being lax or rusty, sloppy technique doesnt have as much of an effect with less recoil Which Nathan has basically said. I don't feel like I'm lacking power or performance so I could stick to what I know.

However there is the typical male, (for me at least) more POWER! Yeah! And I think I would be ok managing it. But it's not even so much the power, looking at the impressive 180gr bc and laser wind beating trajectory and the homework Nathan has put behind it. There's an exact recipe on here.... Tru-flite 4 Groove canted land barrel, dies, load data. All set to go, the works been done all layed out is very tempting....

Thanks everyone.
