Hot Diggity Skippy !!!!

[HTDUCK]

Creedmore and I got some trigger time at the club today.
Shooting the 700 22-250 with the 1/8 Kreiger barrel at the 200 yard line.

The original load with the 77 SMK was so so.
Had the same load: 36 grs H4831SC topped with a 75 AMax
Didn't adjust the seating stem, just loaded 'em.
OAL was a tad longer.
I didn't shoot this group, my buddy Mark (RedGun) did.
I was in the loading room working on a 308 target load.
The result

Since SPS had the 80 gr CCs as over runs a week or so ago I had to try them too.
Again, same load, didn't adjust seating stem in the die.Just shot 'em.
OAL was about .045 shorter than the AMax loads
First 5 at 200 yards

Back to the loading room and duplicated the 80 gr CC load.
Had to try it again.
Shot #4 was all me.
Screwed up a perfectly fantastic group.

Think I'm set.
Also think this rifle is gonna get some better glass.
That $100.00 Vortex Crossfireworks but.....

Oh and FTR ?
It was about 76 here in Dallas today.
5 mile an hour winds from the NW.
A beautiful day to be at the range with a couple of good friends.

 

[Guy Miner]

Wow - pretty doggone good 200 yard groups.

I like those fast-twist barrels!

 

[Elkman]

A great group, your friend and rifle are great shooters. !!!!!

 

[DrMike]

Very nice groups. However, you still didn't hit that dime.

 

[usmc 89]

Any idea as to the velocity with the 4831?

 

[JD338]

Howard,

Very nice groups, way to go.
and to think playing with the col might make those groups even better!

[CatskillCrawler]

Why so many manufacturers stick to 1in12/14 twist with this cartridge is beyond me.

Those loads look good! Never heard of anyone using H4831 in the 22-250. Sitting on the edge here about your velocities.

Dang Howard, that is exactly what I have always wanted! A 1-8 twisted 22-250! Talk about a fun rifle and with the ability to sling them bigger bullets, it would be a TON of fun!

Great shooting buddy! Looks like you have a serious shooter on your hands...

[HTDUCK]

We chronied it with the 77 SMKs at 2950.
Did not shoot through the chrony yesterday as we were just trying to see if it would group well with different bullets. I have not been able to find any 77 SMKs so was looking for a substitute.
Creedmore's dad hooked me up though, gave me a 500 count box of the 77 SMKs.
I'm not seeing any pressure signs and probably can increase powder charge and play with seating depth as well if I really want to.....

And FTR? I did shoot the two groups with the Nosler CCs. Mark shot the group with the AMax's.

 

[FOTIS]

Great Job!

 

[CatskillCrawler]

Very nice. That's a totally different list of powders than what is normally envisioned for that cartridge when it is hamstrung with the slower twist rates. Those long. hi-BC bullets definitely brings the 22-250 back into the long range arena.

 

[SJB358]

That's awesome Howard. Looks like QL is running pretty close to true numbers, so yup, looks like you have plenty of room to increase charge weight..

 

[Kodiak]

Mike,

some shooters cain't hit the "dime" or even a dollar-bill, you's truely included in that group. A lot of my shots even come-down in the adjacent zip-code, but we keep on atryin' !

Looks as though HTD is gettin' 'er dialed-in pretty good.

 

[ScreaminEagle]

Very nice shooting!

 

[sask boy]

That is more that fair at 200 yards. Once you adjust the seating it will be even better :wink:

Blessings,
Dan
