    I'm in a little cunundrum. I want a 7lrm but the difference in velocity seems like about 150fps with the 180's between the two. The difference in price for the dies and brass is huge. Win vs hornady brass and propriety vs standard dies. Also the cost of the reamer and gunwerks to do the work is a big difference from what I normally pay from benchmark. I also pay no shipping to benchmark.what do we do here?

    7LRM??? What's that?

    Send the action to Kreiger and have them do the whole thing.

    If you are looking for a hot 7mm, check out the 7/338 Norma

    Budget is his concern including reloading components/dies etc.

    I don't see the added value with going to an even bigger case than the 7mm STW or 7mm Rum. For the cost you aren't gaining all that much and for the cost per round you're adding a lot.

    Consider the 7 Dakota. Same case capacity as the 7 STW without the belt.

    Ok here's my problem with this. Dakota brass is now being produced by hornady. The dakota is even more expensive than the 7lrm. Hornady brass isn't much better than winchester so its harder to justify the massive increase in cost when these rounds are hard on brass. Another gripe I have with the dakota is that you open the bolt face up to accept it and then that's it, you have to stick with the dakota cause now you can't use any cartrige on a. 535 bolt face. Couldn't I ream it to 7wsm then ream it out to 7lrm if I'm not satisfied? I just wish lapua would come up with a new 7mm cartrige like they did the 6.5x47 just a 7mm on a magnum bolt face.

    You can always get someone, if you don't have access to a lathe, to turn down the case head to the normal size bolt face. It's only .010-.015". I have a lathe so that is what I would do.

    Can you shed a little more light on justifying the costs for the 7lrm?

    Yes. Buy 100 rounds of the Gunwerks ammo. Buy the dies. You are set for a while. When I bought mine I bought a lotta ammo because I just had twins and dont have near the time to reload and work up loads now. So I bought 360 rounds of ammo and the dies. When I am out of the ammo I bought I should have more play time the twins a little older and then I have the dies to reload all my brass. It is a very accurate round. THe gun just feels natural and is just easy and a pleasure to shoot.

    100 rds of gunwerks ammo for the 7lrm is $400! Your 360 rounds is 18 boxes of there ammo. At $80 a box that's $1440 of ammo by my math. I just can't justify $400 for 100rds of ammo and $190 for there dies...there is good news to this. Gunwerks is having headstamped 7lrm brass made and should be out in febuary. They are also having dies too! Aaron quoted me roughly $1.25 per piece of brass and $75 for dies. He also said after that you can get a reamer from kiff once they finalize the print. This is much less than any 7mm dakota brass without dealing with the bolt face issue. I'm happy but now I have to wait.

    So basically its a 7mm Dakota or more accurately a 7mm-300 Dakota. Sounds like alot of money to spend when you could get the exact same performance or more in a standard commerical chambering such as the STW which will match it or the 7mm RUM which will exceed it.

    I am sure the guns are quality but it seems like there are alot of guys out there saying that they have developed a new wildcat that offers great new performance but in the end, they are no different then whats already out there only packaged a bit differently so someone can hang their name on it.

    I had some say the same thing to me when I came out with my 7mm AM many years ago, that was until they realized that it was in fact getting legit 3300 fps with 200 gr bullets and +3500 fps with 160 gr Accubonds.

    As far as barrel life, its more myth then anything else concerning extremely short barrel life with larger 7mm magnums. Now if you want to shoot the thing 500 times a year, ya, your going to dramatically shorten your barrel life. If you get the rifle set up and use it for big game hunting, even the most extreme 7mm will last you MANY, MANY hunting seasons.

    My lightweight 7mm AM is driving a 160 gr Accubond at 3450 fps (26" barrel) and has over 700 rounds down the barrel. I started hunting with it in 2003 and to date it has taken nearly 20 head of big game at ranges past 500 yards with half of those being over 700 yards or more. Longest being around 920 yards. This is out of a sporter weight rifle with 3.5-10x 40mm Mk4 in the saddles.

    Point being, from what many of the "experts" warned me about the 7mm AM, its barrel would never last long enough to develope a good load. Since that time I developed a great load with the old 200 gr ULD RBBT and used that for three years, then developed a load with the 175 gr SMK that was great and used that for a couple years when the ULD RBBT was not available, then switched to the 160 gr Accubond and have used that load for four seasons with nothing but great results.

    This year I checked its 100 yard sight in which is supposed to be 2.8" high at 100 yards and it cut a 0.325" cloverleaf. This from a barrel that for all intent and purpose should have been shot out many years ago.

    Point being, how you shoot and care for your rifle will make much more difference then what its chambered in concerning throat life. Keep it clean, keep it cool and it will last you A LONG TIME as a big game hunting rifle. Shot 5 shot groups, do alot of load development and ya, you will eat up a barrel faster so its more on the owner then the chambering.

    If they get formed brass made up, that would be a huge benefit, especially if its stronger then the Dakota brass that is currently available. Till then, it would offer nothing that the 7mm Dakota or 7mm STW would offer you except a higher price tag.

    Just my opinion. Not flaming anyone here, I just get bored with all these new wildcats doing nothing but the same old thing......
