Rem 700 Classic 350 Rem Mag

7th edition Hornady Handbook lists 2.955" COAL for a Remington 600 350 Rem. Mag. (18.5" 1:16 barrel), and a rather impressive 2700 fps MV maximum with 200gr bullets.

For comparison, the 350 Rem. Mag. SI (Slamfire Improved ;)) boasts a COAL of 3.200". On my to-do list to see how fast I can safely fire 200gr TSX bullets. I would conjecture ~3100 fps.

Hornady knows a lot more than I do... but I wonder if they are simply loading these rounds singly and not feeding from the magazine ... the chambers for 350 Rem Mag - at least mine, does have a lot of freebore ... fwiw - 2800 fps (even 2844) with 200 gr spire points is no magic from the 700 Classic barrel ... maybe 2700 from the 18.5 is no big trick either ... particularly if loading them out that long.

Remember 'if you cant be handsome - be handy' !! :) work up carefully!
 
Listed as a Remington 600 Carbine. Maximum COL is stated as 2.800". In the data section, 200gr SP and RN COL is 2.800". For 250gr, 2.955" COL SP and 2.930" COL RN. Unknown whether freebore varied among the various models. No mention of single loading.

Speer No. 8 has the .35 Rem, .358 Win, .35 Whelen, .350 Rem Mag, and .358 Norma Magnum fwiw...

No. 11 adds the 357 Magnum Rifle and the 356 Winchester but drops the 35 Whelen for some reason.

I guess you have to keep buying them... but they are addictive - like popcorn

(edit to add .. and #12 adds the 35 Whelen back again - it doesnt look like I have #9 and #10)

Barnes Reloading Manual No.3 lists top velocity as 2511 fps with their 250gr bullet and 56.0 grs of IMR4064 in a 24" barrel...

3rd edition Hornady Handbook lists top velocity for the 350 RM as 2500 fps with their 250gr bullet in an 18.5" barrel. Rather odd that such a big difference in barrel length makes very little difference in muzzle speed. :confused:
 
Yes...seems small variation..but I suppose probably a good reminder of the old oft stated warning that rifles differ. AND all data should be 'worked' up to. The various notes on differing OAL length from spire pt to round nose is a little troubling if taken as gospel because not all chambers are cut with the same freebore and folks really should test their specific bullet for OAL in the chamber to be used....BUT....COAL is also a factor of the magazine length AND the action port size since presumably you will want to load from the magazine and eject a loaded round from the chamber once in a while and not all rifles have the capability to be unloaded from the bottom........ I am a little suspicious of COAl of 2.9+ measurements for any bullet type: round nose or spire point..... in a short action Remington

I get excellent results with much slower burn rate Reloder17. I can seat the bullet to the neck base and safely get 2700+ fps MV (24" 1:12 twist barrel).

Medium burn rate powders listed in both manuals for the 350 RM. Seems to indicate that complete medium burn rate powder combustion is achieved in the shorter barrel length and nothing is really gained with the longer barrel.

However, using a sufficient quantity of a slower burn rate powder afforded by seating the bullet out a lot further as I've done and using a 24" barrel to permit complete slow burn rate powder combustion MV is increased substantially at safe pressures.
 
I have worked up a load for my KS 350 using 225 ABs with the tip clipped off and filed flat with the end of the jacket, with a COAL of 2.80. Using a CCI 250, R-P brass and 3031 to achieve just over 2900 fps through the Oehler Mod 35P and right around 1-1 1/4" @ 100 mtrs. I tried all the appropriate powders and this gave me the best accuracy and velocity in my rifle. Maybe want to give 3031 a try DG, especially with the shorter barrels.
Pics of my modified bullets and loaded rounds over on the "What have you loaded today" thread on the reloading forum.

The contour of the barrel on the full stock 350 appears very light, the same as my KS.......bought my kid a used Mod 7 CDL 350 and the barrel on that is much, much heavier.........changes the whole feel and balance of the rifle. I like the weight and feel of my two much better.

It's easy to do so I'll just repost them here, only takes a few seconds when photobucket is co-operating

I'm going to try to work up to that one Douglas........ the Ruger I have will take them without having to file or clip the tips and those happen to be the exact bullet I picked up for it.....
 
Hornady 9th ed still lists 2.930" COAL for 250gr RN(I also have the 3 and 4th ed.s) but the 250gr SP is listed at 2.955" COAL. They still list the test rifle as the Rem 600 carbine with 18.5"bbl They must be seating to the Cannelure(which I cannot with Horn 250sp bullets in my Ruger and fit the magazine). One of those reloading manual mysteries. My rem700 SA mag is 2.810" so I'd have to do the same as Douglas and clip or file bullet tips. I did manage to get 225 AB's to work through the action but got terrible accuracy(only tried W748 with them). I sold my remaining Accubonds to an optimist in the Yukon with a 350rm, I hope they work for him.
 
I did have a big box of powder from Higginson labeled 'use 3031 data' (forget the number...possibly #49 - CORRECTION ... it was labelled #44) anyway it gave very impressive 'fireballs' out of my barrel. I discontinued use of it when I noticed that when I moved the containing heavy plastic bag (lining the box) that the powder gave off an orange cloud of dust. It was after disposing of the powder on a lawn I discovered that one should NOT believe the 'internet' experts who say old powder is good for the lawn!!! That is absolute BS...nothing grew on large patches of that lawn for several years after!
