I load 58gns of IMR 4320 behind a 225gn Sierra for 2720fps. Its the best load I found after testing a variety of powder/bullet combinations.
The rifle is a 1969 build Remington 700BDL with 24"bbl

A good friend of mine uses H4895 for loads in his Ruger M77 .350RM

I've read lately that some are using TAC in Their 350's. I've never tried TAC. Feeling like I should. I think that I also read that You should use magnum primers with it. ???

I have tried TAC in two .350's, a Ruger 77 Mark II and a Remington 700 Classic, and got excellent accuracy and the best velocities I've ever seen from the .350, using both 225 and 250-grain bullets. The data I used is in the latest Barnes manual.

I am planning to try ~ 56.0 grains of TAC because I have about 5 lbs on hand. I have been using R15 and 225 grain Woodleigh bullets (bought a bunch when prices were good) with great results. I use magnum primers.

this was 250 gr Hornady round nose (#3525) over 55 gr. H4895. target was somebody else's left hanging up so i put a few on it before i went longer to the steel.

of course, i don't get groups like this all the time...

I don't have my reloading notes in front of me but I can remember some of my favorite 350 Mag loads out of my Ruger MK II. I have used both IMR4320 & H322 with the 220 Speer FP bullet. I know both loads were a grain or 2 under book max and with either load I was achieving about 2,560 fps. Accuracy was just over 1" for a 3-shot group at 100 yards. I have used this bullet for deer hunting and it has worked very well.

I also tried just a few reloads using TAC and the Barnes 200gr TSX. I've thus far achieved around a 1.5" 3-shot 100-yard group but I've not yet played with the seating depth. I was using 1 grain below the Barnes book max and the average MV was around 2,880 fps. Though Western in an e-mail told me that TAC works well with standard primers, I thus far have only tried Federal Match Magnum primers in my reloads. I'm confident that, if I ever get the time, I should be able to get better groups with the TSX by adjusting the seating depth (though 1.5" group at 100 yards is really all I need). I've yet to take any game with the 200 gr TSX.

Good luck.

Mine is a 673. It shoots everything very well. Even factory loads. Here's my favorite MOA load and it packs a whallop! Stole it from Ken Waters:

.350 Remington Magnum - Lot "A"

Primer: WLR
Powder: IMR 4895 55.0 Gr. (See Below) Listed as "Near Max."
Bullet: Speer Hot Cor 250 Gr. Spitzer
OAL: 2.900"
Case Usage: New Remington - Peters
Remarks: Ken Waters "Pet Loads" p. 411 says "near max., good load." He's right!
IMR 4895 is definitely a good powder for this round.

Start lower and work up!

Just starting to work upoads for a Rem.660 I've had for 20 years.My latest manual Hornady 7th Addition shows max load of H4895 with their 250 gr RN[3535} at 49.1 gr...? You are shooting 55 gr? Just asking.. Never mind... you are shooting IMR 4895

minnmarcus, no, i'm shooting H4895.



from Quickload:

55 gr H4895
250 gr Hornady SPRN (#3525)
2.8" coal
60826 PSI (max. is 62366)
2559 fps from 22" barrel
2453 fps from 18" barrel

the Hodgdon site and their #27 reloading manual lists 49.5 gr. H4895 starting as a load, and 54 gr. as max.

this load is well behaved in my rifles (Rem 600 and 673), but work up as always.

Hodgdon internet data (today) shows:

250 GR. HDY SP IMR 4895 .358" 2.930" 56.0C 2485 52,500 CUP

This is the max. load for IMR 4895. The 55.0 gr. load is pretty stiff for my rifle.

The most accurate loads, .7 MOA, in my Model 600 have been with 250 gn bullets at something over 2400 fps.

250 Hornady, 59gn Reloader-15, 210 primer, 2.80" OL, 2445fps
250 Nosler, 53gn Benchmark, 210 primer, 2.80" OL, 2435fps

Substituting the 250 Speer for the Nosler gave 1.5" groups, 2415fps and shot to the same point of aim.

Reloader-15 was OK with the Hornady RN but under the 250 spitzers had to be squished too much for my taste, prompting the change to Benchmark.

225 bullets, Nosler and TSX, were very accurate at about 2470fps but groups opened up at higher velocities.

I would not increase the above loads at all and advise reducing them by at least 2 gn to start with.

Have not yet tried TAC but suspect that it might be ideal. The Ramshot manual suggests 53 to 59gn for 225gn bullets and 50.5 to 56gn for 250s.

Cheers,
Walt

RL15 made it happen in my 350 RM... 250's at 2,620 in a 22" barrel.
