.338 rum reloads

[QuietHunter]

For the 338 RUM Model 700 LSS I am loading for, here is the best 300 SMK load to date. PLEASE know this may be high on the pressures, but I have seen no signs of pressure in THIS rifle. In other words, work up to it.

300 SMK
92.5 gr H1000
Remington Brass
Federal 215
COL 3.675

Shooting at .4" in this rifle.
Load is a bit compressed.
2750 fps over my crappy Chrono.

Rifle is factory 700 LSS with a slimline muzzlebrake on its 26" barrel. Bedded and factory trigger set to 2.2 pounds.

Please work loads up to this load carefully.

the only load i have tried so far is the sierra accuracy load with a sbt 250 retumbo 96.4 if i rember right.it shoots good but could have done better it was very windy that day.the only problem i have is the bolt hits my hand when i shoot it.it does not have a brake it's a sendero sf 338 rum.i tried a glove it helped so i went and got me a dirt bike glove.i think it will work great it's very padded,thanks,keith

I've too have a Remington 700 LSS in .338 RUM, and have been doing quite a bit of load testing, as well as working out the bugs in the rifle.

So far the good loads are:
250 gr. Gameking, 83.2 gr. IMR4831, 2859 fps, 9/16" pattern.
250 Gr. Gameking, 87.3 gr. WC852(s) 2920 fps, 0.75" pattern
225 gr. Hornady, 92.5 gr. WC852(s), 3092 fps, 5/8" pattern

I can get +3200 fps with the 225 grain pills, and almost 3100 fps with the 250 grain pills before I saw signs of pressure.

Right now I'm working up loads for the 225 grain Accubond.

i sent a sendero off to hart to rework it now shoots like a bench gun.pet load is VVN 560 92.1 smk 250 grain at col of 3.720.the velocity is 3100 out of a 28.5 inch barrel.the 3 shot groups are .208 at 117 yards.i use to shoot 5 shot groups then i talked to a guy at mcmillan rifles and he said 3 shot groups test the load and 5 shot test the shooter.when i shoot at 800 or a 1000 yards i do shoot 10 shot groups.the next box loaded to a col of 3.735 so i checked it with a davis sds tool i got from sinlair and they were about the same.it checks it off of the ojive{sp} of the bullet and not the tip.the bonus to using it is when you change bullets lots or weight or style you can set them all the same by the ojive {sp} reading and forget about the col,thanks,keith

There are a couple things to check with your set-up.First the battery needs to be replaced regulary even if not used as they go bad.Second you may be getting false readings if you have it too close to the bench.
