Home Forums Reloading Big Game Rifles 7SAUM - AGAIN

Not going to load it that hot with the 17 CLB...when time permits I will do some with less powder.....I sould be getting no tight lift at 3200...maybee... But I will work up from lower and see how the groups go...If I can get them grouping @3200 with no preasure signs I will be stoked.
The brake is to be able to spot the shots as even the light load has to much lift to spot the shots

The 2209 light load with 140 VLD's certainly opened well on goats...
Exit hole at 240yrds (not to gory I hope)



the one shot at 40 had a bigger hole but had my sons 100gr 6.5 BR hole beside it so wont bother posting that (He asked me to finish it but I would have said it was about to drop as his was a good shot)

RL17 update....59.5 gave me a reasonable group with the 140's and at 3185fps still 200fps faster than AR2209 (H4350) and no preasure signs at all...no tight lift and brass hasn't moved, 60.5 was the start of preasure with slightly tight lift but the primer looked OK, 3268 fps and crappy group...will load 59gr and 59.5 again before I decide weather I stick with the slow but deadly accurate load or settle for OK group and the extra 200fps:)

DAMN that's all I can say DAMN!

L - I get 3150 with H4350 in my 7 SAUM shooting 60.0 grains.

Have you tried a bit more powder?

I bought a pound of RL17 today to try in my .260 Rem. I'll have to give it a try in my 7 SAUM as well.

I went futher with the 2209 (4350) until I hit preasure and the groupes opened a bit.....not bad groups still....sub MOA but still not as good as the slower load, I am using 210 primers so might get a bit more with magnum primers but in the past I have had better groups with LR primers with similar cases and 2209

But when the weather settles again I have some loaded @ 58.5 - 59.4 in .3 steps with 17 to check the groups....(215 pimers with 17) be nice to have 3200fps

Don't get caught up in chasing velocity.

i got rl17 to shoot in the .3 with 160gr accubonds but fps is only 2777. but that is fast enough for me if it under .75 and slow like that i can live with it.

yeah I have more loaded at the slower speed if I need to hunt with it they will be used.....Idealy with an extra 100fps gets me to the distance I want with plenty of energy....at the moment its just short but looking how well the VLD opened it may be enough enegry as is....wont be testing it for a while as its Lambing time over here so no shooting goats on the bluffs for a while (testing as in taking goats around the 4-500 where it still has plney of energy)....600-800 yrds is as close as we can get for some of the bluffs and the 300RUM works a treat but its as heavy as to lug, hense the rebarrel on this rifle to give it legs then its the cart rifle and longer shot rifle.....

I load 140 grain ABs for a friend who has a Remington TI in 7 SAUM and we are getting around 3,150 with 60.0 grains of IMR 4350 and around 3,130 with 62.0 grains of RL-22. These are maximum loads in his rifle.

I have been loading these for my .280 AI (which has approximately the same case capacity) for several years. I can get around 3,150 with several powders, but using 61.5 grains of RL-22 gives a me smidgen over 3,100 and the best accuracy. I think that you could probably find a load that would approach 3,200 with a 24-inch barrel, but the pressures would likely be more than I would be comfortable with.

3150fps is the required speed for me to get the energy I am after and I can acheive that with most powders but accuracy has suffered (being fussy with the groups for longer shots), I am loading mag length so that will hinder my speeds a bit as there is a big jump (may try closer and if the POI is good may single load for longer shots), Reloader 17 has the required speed and at 3200 is well down on preasure compared to others at lower speeds.....maybee a longer preasure wave gets the speed....more efficent burn for the full length of the barrel?

Heres hopeing the lighter loads of 17 gets the mint group and 3150+......

Next if that doesn't work will be to up the pills size to use BC to get the range but as I had the 140's there and they do shoot pretty well in the rifle I was hoping to stick with them

Time will tell

Now this thread is getting really interesting isn't it.

Went down the same road. I'm shooting 160 Partitions at 2950-2975 using H1000. I just ran the numbers, at 2950 and a 3" zero at 100 yards, the bullet will be down 30" at 500. Don't expect to shoot that far but its nice to know that I can hold on hair and still kill the animal.

I went down the road of hold over and now dial the ranges with the zero at 100 as you can do charts for different altitudes etc and just tape the relivent chart for the area to the stock (it is not uncomon to have 4,500-5000 feet diference in alt in area's over here), then dial for the ranges...... as past 300yrds you have ample time to range the animal look at the chart taped to the stock, dial the scope and hold dead on where you want to shoot....bering in mind as you get further out the bullet is going on a down hill angle so the further out you shoot you lift the POI slightly

With the 100yrd zero it also takes doubt out when head shooting the meat fallow we take ....head shots only on a farm we take meat animals from but you can usualy get within 100 yrds so its nice to put the cross where you need it...and I can adjust up a click or two if its nearer 200

The 7mmSAUM is a very capable cal.....ging to sell my 300RUM as the extra punch is not needed over here...no beers or the likes

No beers - blaspemy!

ohh make that plenty of beers and no bears oh and plenty of Rum and whisky tooo

Anyone shooting the 120 TSX or TTSX in their 7SAUM? I have a good 140gr TSX load with H4350 but for some reason have been getting pressure signs with the same load and 140TTSXs,and also with the 120TSX and H4350 at less than max listed Barnes loads.I'll be trying some H414 tomorrow. Monashee

Very nice!

Rancho Loco,
How far off the lands are you running your 120 TTSX?
I am having problems, like 2.5"-3.25" groups with the same load using TSX's out of my M7 is why I ask..
Thanks

Primers? They may be shown on your target info but all I am getting now is a RED X...
