Home Forums Hunting & Shooting Hunting Rifles Kimber Roulette(finally got burned........)

Any insight into mag length vs throat length? Were you able to get close to the lands? Nice rig.

Hawk, they do work on cows.

Ed, good deal. Mine showed up on Thursday.

JSH, according to my measurements I can get within' .020" with 150 Partitions(loaded at 3.340" which is max useable for the mag-box). 150 BT's and AB's are .040" away at the same COL.

FWIW, I swapped trigger guards about a week ago to a stainless(original version), the rifle now weighs another 1.7oz's.

New aluminum version is only .8oz, stainless 2.5oz.




Drinking beer on a Saturday afternoon. Bored gack posting.....



140 AB's look like they'll shoot good enough for 400 yard deer and antelope hunting. Still appear to be averaging 3030-3050 fps at 60-80F. Too frikken warm to really get a hunting load but at least a guy can figure out that the rifle is capable. Might kick it back up a grain for the colder weather.

Was shooting by about 6AM this morning and finished up before the wind arrived. Zero breeze which has been a first!


The vertical stringing was the barrel(I think....).



Still don't 100% trust the setup yet but it always seems to make a nice little group with the first 3 shots. Of course a 6x scope and the human element also play a factor. Pretty much call every shot a flyer before I check with the spotter....grin

That's work all day long SamO. Nice shootin'. Those 140 AB's are nasty......

Sam, when I got home with mine I looked around in the reloading room and found an older Montana stock back behind some other stuff Darrik had left there. My rifle also now has the old style trigger guard. That's what he gets for leaving stuff in my reloading room.

Doug,
If that's the green painted extra Montana stock from the 7-08, I'm calling dibs (back)!!

Nope, this is a black one he got a while back, a shortened youth model. Sorry Marty........

Didn't you buy that one back?

Nope. It must have gotten sold with one of the others we've "traded"...

Doug, the stainless are way more pimp for sure.



JG, 140 AB's and H4831sc is the uber combo.

Oddly enough, I have a Tikker in 270 that loves that combo. Wanna trade?

Sam, when you get done with the preliminary stuff and are ready for some serious bidness lemme know. Cast bullets will cut those groups by at least 12% at half the range.

D

Deernut, no.....grin



Dan, that sounds great!



And speaking of accuracy this was a 243 Montana the same day as the 270.





Not bad for a 6lb 3oz scoped rifle shooting 90gr/3150fps at 400 yards, 'cold' bore POI does shift depending on the temp.

I am gonna make some +1 grain winter loads and retest when it gets cold.

Good shooting, Sam.

Sam,

I went through the thread twice, maybe missed it, but where did you land with the 4831 / 140 gr AB combo? Charge and velocity?

Ted, no wind..


Ed, I think 58-59 grains is the sweet spot(CCI 200's).

3000-3080fps on several different days(all +50F).

59 grains will probably be the ticket for colder weather.

Thanks Sam. Always been a 338-06 or 35 Whelen elk hunter (Ed Keith?). Drew my Colorado tag for 2015 with a bud that I have not hunted with in years (certainly his last given his age) and want to run the 270 Montana. Thinking the 140 AB will work. Just been a fatazz bullet guy for years...

Good thread, just finally bought my new Mountain Ascent, with some trepidation, last month and shot it for the first time yesterday at one of my gun clubs.

280AI-Nosler brass, WW Mag. primers, 65-MagPro, 160 NPs.....tiny groups, but, hard to hold well in the wind we had.

I LIKE this and am very satisfied with the overall quality, expect to use it a LOT.

I'm onto my second 270 Kimber Montana. The first one was the same. One and a half thread contact. The second Montana had a longer screw. Perfect size, go figure. Serial no. 4831 :-)

Ed, all I know is they work great on buck deer.


Snap, if shooting very far I generally have a bipod attached and that really settles the rifle down. Purists be damned....grin


A lightweight rifle with a bipod attached might not balance 'perfectly' but I think it's the way to go for a walk around open country hunting rifle.




Might remove 1.5-2" of barrel.



Chiro, my (older)243 lug screw was shorter than the 270(which was fine unbedded) but I ended up replacing them both after bedding.
