I have used Nosler 175 ABLRs for about 6 years now in a 7mm Rem magnum, from from BOTW in Cody WY. I handload for it, using H1000 (most reloading manuals have load data for this bullet weight/powder type), but starting load development at 65 grains and working up should be safe. Primers were Fed 215M and Brass was Nosler; Muzzle velocities are around 2850-2875 fps, which is a fast, yet safe and not "hot" load. I have also shot 180 Bergers and 180 Hornady EldM bullets, loaded by BOTW. These are also going about 2850 fps. Before the Covid-era primer and powder shortages, BOTW typically used H1000 or Retumbo with these 180 grain bullets. An interesting fact about all three of these bullets: the ballistic data and the point of impacts are near identical so I can use the same custom turret, out to 600-700 yards or so, as long as my 200 yard zero is the same (sometimes I didn't even need to move the scope more than 1 click to rezero between these different bullets). Other powders to consider for these 175-180 bullets in the 7mm Rem mag are N565, IMR7828SC, R25, R26, R33, Magpro and the New Winchester HD powder. Powders like H4831SC, N560, N165, R22 and R23 are a bit fast for these heavy bullets, but will work if needed.
On larger sized game animals, the Nosler 175 ABLR has shown more consistent penetration and weight retention than the 180 Berger or EldMs, but I have not had any issues with any of these bullets failing or exploding I have also shot 168 Bergers and 162 Hornady EldX bullets in my 7mm, but prefer the 175 ABLR, the 180 Berger and 180 EldM as muzzle velocities are under 2900 fps (keeping speeds of target style bullets under 2900-3000 fps is less likely to cause failure on close range shots (especially on 50-150 yard shots)), than the 162 and 168 grain projections, which are around 3000-3050 fps. I did have some penetration issues on close shots (around 100 yds) with these lighter bullets. The largest animal I shot with the 175 ABLR was a WY Shiras moose (approx. 90 yards) and I shot a few Wildebeest and Zebra in Africa, from 100-300 yards. The weight retention and Penetration on these 175 ABLR bullets was better than the other 2 mentioned.
I am also a Fan of Monolithic bullets for the 7mm in the 145 to 155 grain Weight ranges: Cutting Edge Laser or Maximus, Badlands BD2 or SBD2, Hornady CX, Barnes TTSX or LRX are all good options. The Nosler 160 Accubond or Partition would be solid bullets also (they are "tougher" and have thicker jackets than the ABLRs). I have not used any Hammer bullets, but they seem to be popular too. What I like about the 175 ABLR, is it's ability to hit hard at both close and long ranges, due to it's construction and High BC. I have shot a lot of steel and rocks out to 1300 yards, and the accuracy has been excellent too. In talking to other experienced reloaders/shooters, the 180 EldM and Bergesr are generally easier to find an accurate load for, over the 175 ABLR, but I have not had issues with any of the three. My 7mm is not picky though and the guys at BOTW told me my barrel was a natural shooter with almost any type of bullet. The twist on my barrel is only 1:9 which works for 180 grain Lead core and up to 155 grain Monolithic bullets. The 160 Badlands SBD2 and the 168 Barnes LRX will not stabilize in my rifle. These long, monolithic bullets need a 1:8 twist or faster to function correctly. I hope this information is helpful.
