I like the Federal "Premium" 300 gr. JHP in my ported '95G. Easier on my shoulder than factory 200 gr. RN is in my 336, IMO.
Extremely accurate in my rifle with five-shot groups of 3/4" or less from the bench at 50 yds using a Williams FP receiver sight and a Fire Sight front bead.
Handloads using the Sierra 300 gr. bullet at equivalent velocities with AA 2015BR or Hogden Varget do as well at somewhat less cost.
All of the so-called "Cowboy" loads with 405 gr. LFPs that I've tried have been very mild, recoil-wise, as are the factory 405 gr. JHPs from Remington et al.
YMMV. My opinions are subjective and based upon my own tolerance level and experience using my Marlin '95G carbine with its ported barrel and stock recoil pad. FWIW, with the exception of the Federal 300 gr. load and equivalents, I've fired several brands of 405 gr. LFPs and SPs from an 1880's-vintage Trapdoor Springfield infantry rifle without discomfort. they are loaded to very mild pressure levels in deference to these antiques.
As has been referred to previously, there are loads from Buffalo Bore, Cor-Bon, Garrett and some other specialists that use comparatively heavy bullets, either jacketed or hard-cast with GC, that are capable of taking virtually any animal that walks this planet within the limits of their optimum range. Some of them can't be used in Marlin levers due to either OA length or exremely high pressures suited only to Ruger #1 and #3, Siamese Mauser conversions, or purpose-built custom rifles. J.D. Jones of SSK fame has worked-up loads which can only be safely used in arms rechambered to his proprietary specs using 500 gr. bullets which have been used to take all of the Big Five from custom TCs with 14" bbls.
IMO, premium factory 300 gr. JHP loads tailored for the '95 would be suitable for about any reasonable use without undue battering to your shoulder. While I wouldn't extend that recommendation to include the Asian wild bovines, elephant or increasingly rare tiger you may run across in Cambodia, I gather that you aren't going to be looking for them either.
Should you contemplate going into their territory on a regular basis, I'd advise you to consider getting something better suited to the extremely potent loads, like a SS Ruger #1, preferably with a MB and premium pad if you still want a .45/70. Better yet-a .458 Winchester.
