Its 6.5, just not grendel
#1
Hope i dont ruffle any feathers here as this isnt a grendel, but been a member for a few years now and lost everything in the last crash. I started updating my albums and thought I would share these pics so all the older guys that know me would see part of the reason I havent been around as much. I hope to reestablish my other albums tonight and have my grendel back together soon(long story).

Im planning a bolt grendel build soon so as soon as I finish it ill post up results. Comments and criticism welcome, thanks for looking.

Richard

Oops! description of pics would be nice I guess!! Pic 1 is finished rifle, 260 Ackley built on a Rem 700 LA with Rock Creek barrel, MCM A3/5 stock, PTG bottom metal with AICS mags, DNZ 1 pc mount with a vortex 6-24x50 FFP moa reticle. All smithing was done by yours truly. (New lathe has kept me from showing up here much)

Pic two is of factory lapua .260 brass on left fireformed .260AI on right.

Pic 3 is a 6 shot group on left at 500 measuring @2.75" 5 shots on right measuring close to same. (two different shooters)

Pic 4 is another group at 500, didnt measure, all these groups are with FFing loads, really anxious to see what itll do with neck sized FF brass. Oh yeah, these are all 123 Amaxes.

Last but not least is a doe kill at 501 lasered yds. 123 Amax over 42 grs IMR 4350. 2800ish fps. Shot shortly after sighting in rifle and running back to house and loading five more to hunt with! Complete pass thru and she staggered about 4 ft and collapsed.

This may not excite most but being my first rifle build on my own lathe and with no guidance is very satisfying to me!! Any questions, comments, criticisms, etc. are welcomed.

RS, nice rifle. Now I see why I haven't heard from you in a while=dang lathes! Nice shootin man!

I'll vouch for Richard ten times a day. He was my partner on the somewhat --kinda-- Bank glass shoot thingy we did, then never posted much about it. We have the data.

We had 1520- split between us- Texts on our new smart fones, while the project was alive. We did get thru the glass. Shoot the Gloss! Was the line from the original Die Hard movie!
Well, Richard had his own comedy line- he texted me just before shooting the first 160---- Pray For Me !!! I Laughed for 1.5 days before winding down to a giggle mode.

I said to RS-- we are going thru that glass! I sent 4-5 packages of bullets his way- we went thru! I have no reason to Ever Quit ! Inch, and a qtr. thick- laminated glass.

RS share the 160 that went thru- & the 129 IBond. That was close. But not the GMX stuff, please. That's for big red to study --soon enuff.. Your call buddy!

BTW, dude! Help me on the Gmx over the chrono, asap! Thanks for getting reinstated. Probably due to a dude- named blunt force trauma? He must have bonked Hanka on the head.,., ? Hee heee!

Cant find all my old pics. I did find this one of the 160 that went thru. I cant find the one of the glass with hole in it, Ill keep searching tho. It was fun. Tempting to show the impacts from GMX but Ill hold off till later. Still sifting thru pics to put back in my albums. [ATTACH=CONFIG]6164[/ATTACH][ATTACH=CONFIG]6165[/ATTACH]

Nice rifle build Rick! .260AI is a great cartridge with more case capacity and good burn efficiency. You are running low pressure if the 123gr is going 2800fps with IMR4350. With regular .260 Rem loads, you're looking at 2950-2980fps max. Your added volume drops the pressure, and adds capacity.

I have noticed that Lapua .260 Rem. brass has less capacity than Remington, so the wall are thick. Yours might take you back up to normal .260 Rem case capacity published in most handbooks.

Thanks lr52 and everyone.

LRRPF52, if you ever want to sell that Grendel reamer you bought, lemme kno. Boltie Grendel is on the short list, and I'll b needing a reamer. If ur not interested I'm gonna get a Manson, as I'm pretty sure his is saami

LR, yea we're running light loads fire forming the brass. I should be around 2900fps with 140's after fireforming. The Lapua brass is definitely thicker with less capacity. I'm thinking the smaller capacity is gonna push the pressures back to where I need for the 140 gr. I've researched and have notes but can't remember off top of my head. Should be pretty interesting tho with fire formed, neck sized brass tho. I'll prolly bump shoulders .002 on some to see if I'm getting any accuracy difference.
