I've got a 260 remington being built on a Tac30 action with a 24" bartlein medium palma contour barrel. I was wondering if there are any custom ammo manufacturers that i should be taking a look at. I plan on doing some reloading as well, but this will be my first build in 260. I've heard good things about Monolithic Munitions and was going to pick up a few boxes for testing. Are there any other makers out there i should try right off the bat? This is going to be a long range rifle, and i have room to shoot out past 1K yards, mainly groundhogs, and steel/paper.

Any personal experiences? Info is much appreciated.
 
The Federal GM260M factory ammo shoots very well. I use it to shoot control groups with all new .260s I build. This is an average target for one rifle. 3 consecutive 3-shot groups on one target will usually tell me that I have a healthy rifle getting ready to ship. The Federal load seems to be very consistent.

C'mon Terry, don't give us that 3x3 target shit.

Lets see a 5x5!

Hey, at least I'm sending real world targets out with 3 consecutive groups shot back to back on each rifle I build! I'm not picking and choosing what groups to send with the rifles.

I'm also not working up the best load for each rifle. I just want to make sure I have a healthy rifle with plenty of potential going out the door. The average for the typical target I posted was 0.324" and that's a real C2C measurement. I have an electronic file folder for each rifle and this type of target and measurement are valuable for me to document what I am putting out compared to a year ago, 10 years ago or 20 years ago.

I feel pretty confident that I can duplicate the test groups, on demand with each rifle in front of a customer if I ever need to. Actually, I just noticed that my son Luke fired the target that was posted above.

I absolutely agree that statistically, 5 shot groups are superior.

Holy crap, I think I just detoured this thread. Sorry Reaper.
Thank you...... Carry on.....Nothing to see here......Move along....... :)

Only match ammo I've found in stock worth a damn if you don't plan to reload is southwest ammo. But $50 for a box if 20? Holy hell!. I know is lapua brass, but another buck fiddy for one of the less desirable, cheaper bullets, some powder and a primer? Ouch.. I have a 260 build coming in a month or so and already have the reloading components, but was hoping to find some affordable match ammo to prove the rifle before i start with my witches brews.
