Zastava, I have the same rifle, brother has two.
Family and cousins have shot the 160g Sierra btsp for a long time, this bullet really performs well on large deer and hogs from any angle. Also, the Sierra 160g BTSP is easy to tune compared to a lot of the VLD bullets on the market.
We have shot several loads with this Sierra 160g BTSP
for illustration purposes of what is safe in our rifles with our lot# of powder
We shoot Remington brass in our rifles. what we got started with.
a. 65g of R#22, cci 250 or Federal 215; 3000 fps
b. 69-71g of Retumbo, federal 215 and 3100 is the accuracy node in our rifles
c. 61g of IMR 4350, Rem 9 1/2 primer
d. 68-69g of R#25, WINCHESTER MAGNUM PRIMER VERY IMPORTANT
These are close to max loads for our rifles, so approach with caution!! Multiple loads are listed because barrels will have their particular preferences.
Mack Daddy load with 150-154g bullets is with 69-73g of R#25 with a Win Mag primer, 3200 fps at the accuracy node. Less than 10 fps extreme spread. Work up to this load in your rifle. 154g SST, 150g Sierra btsp, 154g Hornady Sp, 150g Nosler combined tec bullet. Barrels do have their preferences. Seat all of these bullets real close to the lands
154g Hornady Sp
63.0g of IMR 4350, Rem 9 1/2 primer-3100 and one heck of a deer killer
Note: the 154g Hornady Sp will shoot holes through both shoulders on large hogs on broadside shots, excellent Elk bullet also.
140g Nosler accubond, 140g Barnes ttsx
65-66g of IMR 4350
Rem 9 1/2
Seat the accubond to touch the lands, jump the ttsx .050 from the lands
I have killed a lot of deer and two bull elk with this load using regular nosler ballistic tips.
120g Nosler ballistic tip
Tougher bullet than you would ever think
72-73g of R#22
CCI 250-VERY IMPORTANT
touch the lands with the bullet
Unreal accuracy
120g ttsx, same load, seated .050 off the lands
Don't be surprised if you shoot 3/8" groups or less with both of these bullets at 3500-3600 fps
We have been playing with the 175g Nosler long range accubond in Rem brass.
Seat this bullet close to the lands, did not like the jump.
62.5g of R#22 shot a single bullet hole for three shot groups, groups kept repeating
Velocity is 2850 fps
this is one of the most impressive loads I have ever shot in my 7 Mag as I have shot single bullet hole groups more than once.
Our Sendero's are all bedded and wear a Gentry muzzle break, old walker style triggers tuned at 2 lbs, and wear high power scopes.
We are going to try R#26 with 215's with the 175 as a friend is getting 3030 fps out of his sendero like ours.
Also, will try the R#23 with the 175g long range accubond as well.
We tried the 150g Long range accubond and had no luck.
If you are not shooting over 250 yards, you should look no further than the 160g Sierra BTSP. If you want a tad stouter bullet, then the 160g Sierra BTHP is tougher than the Spitzer. The 160g sierra BTSP is a notorious deer stopper, deer drop with this load on the spot, near and far.
Best of luck with that Sendero. Sendero's shoot like a $4000 rifle when bedded and trigger lightened. Gentry muzzle break makes it kick like a 243.
As you can tell, me and my family has had a love affair with the Remington 700, Browning A bolts, BAR's, with a few scattered Winchester model 70's and Savage 110's thrown in the 7 Mag.
When people start complaining about their deer running off, we tell them the 160g Sierra btsp in the 7 Mag is THE ANSWER to their problems. Federal loads the 160g Sierra BTSP for guys that do not reload.
