.2-.3 100 yard cold bore challenge

[Jon Bischof]

Tangent: I would't worry about your zero yet, just a smidge of wind blowing to the left could put you off center that much. Shoot it again on a really calm day to see where they really land at that distance. Really encouraging group at that distance! What's your rifle?

Was out today a little bit of wind 12 to 15 r to left. 6.5 creedmoor and 308. The creed is getting a chassis this week n should greatly improve. Eveything is shot at 300yds. The targets faded as they are come from the FBI sniper school and are 100yd targets first and last are 6.5 the middle 2 are 308. The 5 n 1 I adjusted .1 up and .1 right to hit the x i held just inside of the circle right side for all 6 shots. The first shot out of the creed was the only shot with a 147/rl26. I'm trying to duplicate that with either 100v or IMR 4955. So far no luck.
target 1 is 45.5 Rl26 2.845coal 215m Norma once-fired 147eldm coated with danzac. 2840 in the old gun not checked yet
target2 168smk 43.1 Rl15 Lapua br2 2.820 1x fired 2635 sd 3 es 9
target 3 LC not sized right out of the bag with military primer 168smk 43.1 rl 15 2.820 not checked but uses the same dope to 650yds
target 4 Peterson 5x fired cci 200 142smk coated 42.0100V 2.885 coal 2830fps es 18 sd 7 Flat primers no swipe brass needs to be annealed.

I'm left due to the breeze, but I'm high because my 100-yd zero is high. Typical mess on my end: barreled action was settling into stock while sighting in new scope, haha.

Rifle is an LPA razor with a benchmark barrel spun up by TS Customs, Timney 510 trigger in manners T4A.

I've only shot the factory 140 ELDM with this gun, but it hasn't held me back out to 1,400 yards. I'm gonna give Prime a try to see how they do.

First one at 100 yards last week and the last two at 200 yards this morning.

I have a "5 shot",,, "14 set" ladder run coming up with a Old School 6.5 A-Square Remington 700 BDL Hunting rifle...

I'll try my best to post the photos of 1 1/2" moa groups if any of them materialize,,, Ha...

If I'm lucky that is...

I did a 10 shot group on the weekends and ended up with a 1 5/8"s gathering... ha... I had to call 1 as a flier that fell out side on the magic zone...

Must remember to think before moving fat dumb finger... lol

opened a new lot of a varget.
This is at 900yds with the 195tmk out of my 308. Needed to tweak my velocity a touch

 

[GLTaylor]

Incredible! Makes my short range groups look pitiful. Good on you!

Sometimes you get better results tweaking the form factor. Whats your speed n load details. Inquisitive idiots want to know

 

[GLTaylor]

OK, I'll bite. What is form factor?
Inquisitive dummy wants to know!?!

 

[sturner]

There is a good video on sniper hide on form

 

[Capt RB]

Berger lists form factor for their bullers. 4DOF ballistics has that in editable format. The Hornady library of bullets will put the listed number for your firing solution. If 1.0 is given but your high change to .95 and compare actual on target with solution on solver. Some barrels are better than some not as good as. I would guess it involves more than um going to type on my phone. A barrel that shoots with a better coning angle straighter out of the barrel flight will affect a solution at distance with better than flight ie;high shots better wind characteristics than a barrel with avg or poor bullet yaw from the barrel

 

[Jon Bischof]

Can Hunter and Captain RB, you guys are so high above me I can't breathe.

 

[GLTaylor]

Gasp, I'm right with you JB. I'll keep my shots closer
