I currently have a blueprinted savage action sitting in a PDC single shot stock that is wearing a 260AI barrel. I have tons of Savage short actions so it only makes sense that I put the 260 onto one of the SA's. The new 190 berger bullet has intrigued me as does pretty much every other 7mm bullet. Any suggestions on chambering? There is a strong chance I will be reaching out to a mile on Steel with this rifle. Thanks.

Re: What LA 7mm?
284 win is a pretty good candidate and so are the WSM amd RSAUM.
for a long action, the 280AI or the 7STW would be nice also.

Re: What LA 7mm?
I know the 284 Win is outclassed in terms of pure velocity, but guys have been doing some seriously impressive things with it. That new F-class record score of 450 was impressive.

Re: What LA 7mm?
I would go .284 win on a long action. You will be pleased for sure.

Re: What LA 7mm?
Is the Win brass good to go? It would be a lot nicer than buying the Lapua or Norma 6.5x284 brass and then necking up. And would save a boat load of dough.

Re: What LA 7mm?
The 7 rem mag would be better suited to those new 195's, if they come out. I am swapping my 7rm to .284 as it will do all I need with less powder and more barrel life. The .284 win brass is the crappiest brass I have ever used. I wanted to avoid the whole neck up/donut issues with the Lapua brass so I have to work with it I guess. I hope Lapua or Nosler starts making .284 brass.

That's my thought. If you are building a long action why not make full use of it?
I've kicked the idea of a 284Win all over the place and no matter which way I look at it I decide it doesn't fit.
In a short action it can't seat the long heavies far enough out, and in a long action you are wasting 30% of what you could be loading, and for pushing really heavy pills you will want the big boiler room.
In a long action, I'd go 7mmRM.
As for the often feared belt... just get a proper die and ignore it, headspace off of the shoulder after the first firing.

Re: What LA 7mm?
7 WSM, 7 SAUM, 7/300 WSM, 7/300 RCM, 284 Win throated to run in a LA would be my suggestion.
Not necessarily in that order. With a 175 SMK 7mm you give up very little to the Berger 180's and the 175 7mm SMK will transition into mile hits without trouble. It gets surprisingly little credit for the exceptional bullet that it is.

Re: What LA 7mm?
7mm Rem firing 180 Bergers at 3000+ fps is a pretty sweet combination.
For the new 195 I would look long and hard at a 7/300 Win. Brass is easy to come by and easy to form and they will drive the big BC bullets at near RUM velocities without all the freebore while using significantly less powder. This combination will easily be one mile capable.

IMO it's a way overbore barrel eater. By the time you've gotten to know your barrel you've used up half, if not more, of it's barrel life. It's a prime example of an extremely inefficient way to get velocity. Lot's of freebore and lot's of powder.

Re: What LA 7mm?
The 7mm rem is often overlooked due to the seriously underloaded factory loads, and conservative handloading data, but it's not going to get you much with the 195.
The 7/300 Win is capable of launching the 180 VLDs at 3150-3175 fps. This thing could be an absolute laser with the 195. You get STW performance with readily available quality brass without all the freebore. What's not to love?

What length barrel out of the 7/300 is getting 3150/3175fps? As I have a 7dakota 25" barrel and with the 180 bergers hybrids am getting right around 3000fps, also had a 24" rock barrel and was getting 3000fps with the 180vld's but the hybrid's seem to show more pressure quiker.
I have 3 7mm calibers 280AI, 7rem, and 7Dakota and the 280AI with a 24" featherweight barrel 168bergers did quite well at 1000 yards all bullets were in 12inch target with variable winds from 4-13mph.

Re: What LA 7mm?
27-28" tubes are the norm for the velocities I listed. There are several guys that have done extensive research and load testing with it. Do a google search for 7mm Practical. He changed the shoulder angle by 5 degrees in his version, but it's a good representation of a simple necked down 300 WM. It's some pretty good reading with a few youtube videos to watch.
A member here "Broz" has extensive range time and load development with this chambering. He is definitely worth contacting if you have questions.

I'm able to get my long throated 28" 7mm Rem up to 3060 with 180 VLDs and Retumbo with <1/2 MOA accuracy, but case life sucks. I've settled on letting them out at 3025 to save my cases. Barrel length is the kicker here, you've got to have the barrel to get the results. It's interesting you say the hybrids show pressure quicker. I figured since they had decreased bearing surface, compared to the VLD, it would be just the opposite.

Re: What LA 7mm?
I run a 24" barrel in my 7Mag and with 69 gr Retumbo push a 168 Berger VLD at 2930. Plenty of barrel life with a modest load, 25 MOA to 1000, and my brass have 6 reloadings on them and the primers are still tight, oh yeah accuracy in the .1's!

Re: What LA 7mm?
The 7RM is one of choices I could get for 158. It wouldn't be nearly as good as some of the more premium brands, but the price is pretty damn hard to beat.

7mm WSM with Alpha mags is what I use any my long range rifle.
I'm can get over 2950fps+ with 180gr Bergers with enough case capacity and without over pressure.
I'm running 2936fps as this is my accuracy node, which is about 6.6mil at 1000 yards with 1.3mil wind-drift (10mph) at my shooting location.

A properly throated 7RM and 27" barrel runs 180's at 3030-3050 range with good case life. Have built a ton of them for guys all with the same results. Testing a new wildcat right now that is looking like it will provide another 100fps pretty easily in the same barrel length.

Re: What LA 7mm?
It takes a longer barrel to push a 180 with a SAUM than a 7RM. I've seen guys run 26" barreled 7saum with 180 to near 3000, but brass life has to suck... And SAUM brass are harder to find whereas 7RM brass is everywhere. I just like having a short 24" tube that can push a 180 to 3000, but I choose to run a 168 Berger at 2930.
