Sig Cross Handloading..

[Jerzey1]

A little backdrop and then get to my question - I've had my Cross for over a year, went back to Sig for the recall and it's good to go. I have shot it with the Hornady 147 gr Match ELD ammo (6.5 creedmoor) about 5 times and it's a great shooting rifle. I haven't shot it much because I usually go to the range with my 20lb 6mm creedmoor, which is the favorite. I now plan to shoot the Cross more often, I recently put on a new scope - Athlon ETR 3-18x50 and a Banish 30 suppressor to shoot and hunt. I really plan to just enjoy the rifle, practice in the 50-400 yard range for an eventual hog hunt.

I do reload for my 6mm creedmoor. I'm going to now reload for my 6.5 mm Cross. I know Sig has a ton of offerings for ammo, (80gr to 147gr) but just not affordable options for more regular shooting. I was looking to see if you do handload for your Cross and what you reload. I'm thinking in the 108-120 gr bullet range to reload. Please let me know what you do.

I forgot to add (adding now) that my Cross only weighs like 11lbs, rifle, scope, rings and bipod! This is why I wanna shoot ammo in the 108-120 gr size.

I shoot a Tikka 6.5, Not a Cross. I ran some Hornady 140 BTHP American Gunner Match and some 140 ELD Match. I was impressed with both and tried to duplicant them. Bought some 140 ELD and went from there. My range max is 700 yards.

what does your tikka weigh? Im a huge Tikka fan by the way, my favorite is a Tikka. My Cross only weighs like 11lbs, so this is why I'm asking what people are shooting. (I forgot to mention the rifle is very light)

I found a good load with the Berger 135 Classic hunters.

I had good groups in my cross with 41.5 h4350 140 eldm and same charge with 143 eldx for hunting reloader 16 worked good but preferred
H4350

Mine does not seem to like heavy bullets. It really likes the 123gr Scenar though. Running it at 2800 fps with 39.5gr of RL-15.

I just purchased 108 and 120 gr Hornady projectiles......I have Hornady brass, large rifle primers and H4350, Shooters World and Winchester Staball to work with. I might start with the 108's and the Staball.

I recently put on ... a Banish 30 suppressor to shoot and hunt.

Hope you're enjoying the suppressor!

Hope you're enjoying the suppressor!

I am so far. I was told I can soak the internal parts overnight in CLR, and then put in my ultrasonic cleaner in soap and water the next day.......but can I put the outside "can" part of the suppressor in the CLR overnight also?

What did you end up for a C.O.A.L with the 143 eldx? Gonna start making loads for my 6.5 cross and checking freebore, it's plenty long with the edlx. I think it was something like a 0.120" bullet jump using Hornady's recommended length.

Thanks

I’m going to try the 42.9-43.2 range for load development today. I was hoping to be over 2800fps and that looks safe to me

You mean the standard 6.5 and 260 load that works in just about everyone of those guns

I have done loads of testing.

Stock Sig Cross 6.5 without suppressor

140gr ELDM

40.9-41.1gr H4350 (This was pretty good with Winchester Large Magnum and havent tried with cci 250 yet) Not Suppressed
42.1gr H4350 (CCI 250) With Hybrid 46M suppressor

2.830 Coal
Starline Brass 1.910
CCI 200 Large Magnum Primers

40.9-41.1
.4 MOA
2560FPS which I didn't love but they're accurate.

42.1
.4 MOA
2650FPS


143gr ELDX
44.4-44.7gr of Staball 6.5
(Haven't done much work on this one yet but that window is pretty accurate so far)
2780FPS (Hybrid46M)
Starline Brass 1.910
CCI 200

I plan to do some lower charge weights just to see if I missed a window.

Also want to try this with the 140gr eldm but ran out of them.


Anyone else have similar data or a decent window for Staball 6.5 and 140eldm or 143x?
Also has anyone tried
120 eldm
123 eldm
130eldm?

Id like to mess with these after shooting the Hornady 120gr cx rounds.
They were deadly accurate but shooting 800 plus with 5-10 mph winds in MT obviously wasn't the best choice of ammo.
