Has anyone tried these in 7mm rem mag. With modified case the bullet is just below shoulder into the case. This is touching lands. (Have not developed load yet) rifle is a rem 700 sendero. Has anyone pushed this to 3k or higher in 7rem mag. Not sure i have the throat length to do so. Any information or input is welcome. Is this normal with boat tails. My first time loading these and loading long. Just making sure im not seeing things incorrectly. I have not made dummybround on my dies yet to see fits in magazine to see how far out I am. More questions inbound as I mess with this rifle.
165g tipped .284 gamekings.

Unfortunately I cant go much higher in weight. Only have 1-9.5 twist. 165-168 about it. I do have some 175 factory i thought about trying to see if they will even stabilize. Hopefully enough to get scope on paper. So I can start with 165s.

If it's a factory barrel, Rem have 9.25 twist. I run 168g SMKs in mine a little over 3k and no problems but that's in mine. Yours may be different.
It come out at 9.5 when I tested it. Rifle is in really great shape so no need to rebarrel. What I have read it should be possible to reach 3k. Was just curious if others have. Some information says possibly 3100-3200. But out of 7mag not 100% sure.

I may retest the twist to verify.

I sold my remington 700 7mm mag. To buy a Browning Xbolt 7mm mag 1@8 26 inch barrel. I like shooting heavier bullets. I'm shooting Berger 175gr Elite Hunter out of my 280AI. But it has a 1@8 26 inch barrel. The Berger 175gr bullet takes a 1@10 or faster. That's a way to go heavier in bullet weight.
Was hoping to shoot heavy for caliber. I have read different information on yes you can shoot 175 with 9.5 other say no, 190s are to long etc.. guess ill have to shoot few to find out. I can say if I can't shoot real heavy. I not selling my sendero to do so. I sold my big magnum .338 to buy it. Prob not best idea, still kicking myself. But if I want another big .338rum/Edge ill find one. .338wm gonna have to be good for now.
Isn't it it in the marginal stability category. Can you push it 3k out of 7mag. You shooting above 3000ft elevation with temps warm enough to make it work. I know the 180, 190. 195 not gonna work unless I rebarrel to 1-8 or buy 7prc or 7rum, 28nosler etc.. gonna be funy to see if the 175s work at distance.
In our Remington 700s with factory barrels, we shoot the 175g Nosler long range accubond, kissing the lands, bullets sorted by ogive length with amazing groups with R#26 at 3030 fps and R#22 at 2870 fps. Sorting by ogive length and kissing the lands are where the keys to the Kingdom lie. These 175g LRAB put a lot of shock on a deer, amazing.
We have not extended the throats in our rifles, but I do install a Wyatt's mag box that gives me a lot of extra length.
I have barrel blanks and two 7 Rem mag reamers waiting, but the factory barrels just keep shooting amazing.
Many, many people have trouble with the 175 LRAB because they vary by .020 in ogive length, then they just seat to mag length, praying for a good outcome, but often it is pitiful results. My brother has the same experience with the 168s. Again, Both of these bullets like to kiss the lands or a tiny bit of jam, which demands consistent ogive lengths and long magazine boxes, which will result in 3/8" or often smaller three shot groups that repeat. The two issues of mag box length and kissing the lands demands a different approach on action and mag box choice for best results. The groups at 600 yards with a 6x24 scope are shocking in how good they are.

Don't hold your breath on a 7rem doing 3200 fps with a 160-165. Some of the longer barreled rifles do a bit better if pushed, but I've found a 140 in the 3K to 3200 fps range is usually great. A 175 around 2800 is easily doable. A 160ish around 3K should be accurate and easy enough on the rifle too. I typically skip the 160'ish bullets as I run then in 30 cal rifles for a light bullet weight.
