[JD338]

Looks like 3200 fps is indeed doable. Pretty impressive.

JD338

 

[SJB358]

The 6.5x64 Brenneke has about the same capacity as a 264. That's a neat one for sure.

 

[remingtonman_25_06]

Not bad for only burning 60g of powder or so.

thanks Fotis.

 

[elkeater2]

:roll: Ultimate? viewtopic.php?f=9&t=25414. Now that's coyote medicine! I know that's not what you're after Remmy, couldn't resist :wink:

[remingtonman_25_06]

Whats 264 win mag look like with 28" bbl and 140 amax??

Dont think the extra 10g powder is gonna be worth the 100fps gain at most?

 

[mcseal2]

I use a 6mm Rem with a 26" barrel and 1/2gr under Hodgon's max load of Superformance with a 70gr BT for most of my coyote shooting. It runs 3824fps and has a great MPBR. That comes in real handy for shots at unknown distance without time to range.

For the real long shooting with time to range I'm best with my favorite big game rifle. 25" barreled 264WM with 140gr Bergers at 2950fps. The load isn't hot, and the bullets don't perform ideally for coyotes, but that rifle really shoots that load. I know when I miss with that rig it is all operator error.

 

[remingtonman_25_06]

Couple great cartridges and I like your mpbr idea when there isnt a whole lot of time to range.

need to figure out what percent of my shots would be x amount of time as well.

I still think a 6.5 with a 140 is the way to go for out to 1200.

Whats the 6.5x47 lapua say with 28" bbl and 140 amax?

Worth taking a look at the .300 by Richard Simmons. He's talking 3900 - 4000 fps with 110 & 125 grain bullets. It's got to be impressive on a coyote!

http://richardscustomrifles.com/favorit ... rifles.htm

 

[remingtonman_25_06]

I remember shooting the 125g NBT from my 300 RUM at 3950fps, was kinda fun

Thank you scotty.

 

[Oldtrader3]

257 WBee with 100 gr Nosler BT .393 bc at 3600 fps :grin: - what could really be better then that :?:

Cheers RJ

Cost for a varmit load!

 

[Ridge_Runner]

and if ya take care of it and don't shoot it hot the 6.5/06 AI will last 2500 rounds or so and its the easiest wildcat there is to form brass for, just prime a 25/06 case, charge it with a top level load, top level not max, seat a boattail .264 bullet, and shoot it.

Oldtrader ! Cost is not in the EQUATION ! :shock: The 257 WBee is the King :mrgreen: Great balance of Speed and Recoil ! JMO

Cheers :grin: RJ

 

[Ridge_Runner]

my 6.5gibbs is basicly a 6.5/06AI on steroids, but due to the fact I opted for a cut rifled barrel over a button job, I can not surpass 6.5/06AI MV's, but with a 29" barrel it runs 140 bergers right at 3200 fps, just aclown of the 6.5-06AI, there are guys shooting button rifled gibbs that will clock 3340 fps with a 140. I'm here to tell ya a bullet running 3200, with a BC close to .7 is pretty damned impressive when ya look at the numbers, I wouldn't be afraid to push it on coyotes beyond 1100 yards. but there isn't enough advantage to the gibbs over the AI to justify forming the brass.

257 WBee with 100 gr Nosler BT .393 bc at 3600 fps :grin: - what could really be better then that :?:

Cheers RJ

Cost for a varmit load!

Oldtrader ! Cost is not in the EQUATION ! :shock: The 257 WBee is the King :mrgreen: Great balance of Speed and Recoil ! JMO

Cheers :grin: RJ

My .22-250 AI with a 75 Amax gives up less than 100fps to that load, drifts less, and only costs. 40 grains of powder (vs. 70ish in the Roy).

The answer here doesn't start with .25.....

A .264 Winny can run a 123 at 3450 ish for the same powder it takes to hump a 100 outta the .257 Roy.... and you gain .125 in BC (.393 vs .520).... and that's a huge boon when gun goes off. Hitting coyotes at long range ain't about "drop" or "flatness"... it's all about drift and accuracy.

Just out of curiosity.... other than j and remmy.... I'm wondering how many of you guys have actually shot more than a half-dozen coyotes in your lives?

I've killed 5, but I know a bit about drift, accuracy, and terminal performance on game. I know the fast 22's will get it done, my suggestion was made over the 22-250 AI and the 22/6mm AI only due to the longer neck and throat angles seeming to give better barrel life, and a bit better BC, which would help with drift and of course lots more retained energy.

Why are you such an insulting jerk, Songdog? Nobody else here is acting like a petulant 6 year old, except you. I am really tired of being coated with slime by your big mouth and listening to your innuendo.

I am nearly 71 years old and am dealing with several life threatening diseases every day which control my life. What I chose to entertain myself with is none of your business. Maybe you don't have a real job and do not have a family to support? One thing I do know is that your mouth needs to be washed out with soap for being an insulting son of a whelp!

I do not need to take any crap from the likes of you! If need I your crap, I will spoon it out of your brain case! Now go away little man and leave me, alone. Comprenez, bouch de merde?

Keep the peace fella's. We dont need to fight one another. Too much other BS going on in the country to fuss over small, petty things. We each have a preference to what we choose to use to hunt. We should focus more on protecting our RIGHTS to hunt and keep and bear arms.

read his post man, he's 71 has health problems, let him vent we will all be there one day, my guess is he was raised at a time and place where people showed a bit of respect to everyone whether they agreed with them or not. is showing him the same courtesy too much to ask?
