Range Test Mcmillan EOL Outdoorsman

I have now accumulated quite a bit of data with the Mcmillan EOL Outdoorsman in 300 EOL Magnum and decided I have enough data to make a determination about accuracy and loading data to begin a thread on it. The barrel is a Schneider 26" 1-10" twist with a Vias brake. The scope used in the test is a Nightforce 5.5x22.

This rifle is designed for long range hunting with the 210 grain Berger bullet. The chamber is cut to allow the 210 grain Berger hunting bullet to be seated at the lands and allow proper feeding of the rifle which it does. The cartridge OAL is 3.7695" when this bullet is seated to the lands in this rifle.

What I wanted to achieve with the test is to determine the accuracy of the rifle at ranges to 1000 yards with the 210 grain Berger bullet it was designed for. Also for hunters who may be interested in the rifle however choose not to shoot the Berger bullet I wanted to know the level of accuracy that can be achieved with other top long range bullets and factory ammunition for the hunters who do not reload. I tested known accuracy loads with the 200 grain Nosler Accubond, 208 grain Hornady A-max and 180 grain C32 Cutting Edge bullets along with a box of factory Remington cartridges loaded with 180 grain Nosler Partion bullets. For the test I used Retumbo and replaced H-870 with WC-860. Those have been my two best powders for the 300 RUM and the two I have the most data for. Since H-870 is discontinued I replaced it with WC-860 which I have used to develope some extremely accurate loads with heavy bullets in other cartridges.

I will return in a couple hours and finish with an edit. This will be in stages.

Really interested in the results of the CE 180 with a 26" tube, this might be my next rebarrel. Will either do it in scheider barrel or if my rock creek works well rebarrel with another rock.

Re: Range Test Mcmillan EOL Outdoorsman

Could not edit so I will continue with several posts as I have time.

I shot a few groups at 100 yards to zero and then focused mostly on targets 300-600 yards since this rifle is advertised as a long range hunting rifle. The only bullet I am shooting beyond 600 yards is the 210 Berger the rifle was designed for. I just wanted to show how the rifle would shoot other bullets to 600 yards.

All the bullets used shot extremely well. Even the Remington factory loads held well under 1 moa shooting a 1.97" group at 300 yards. Accuracy loads with the 200 grain Accubond, 180 grain C32 cutting edge and 208 grain A-max held .25-.5 MOA to 600 yards. When I post some of the targets you will see excellent groups with all the bullets tested. Overall I could not name one bullet that shot better than the others out to 600 yards since they all performed so well. I would be perfectly comfortable shooting any of the listed bullets. Each bullet shot groups ranging from .25 to .5 MOA. Depending on the individual group each bullet at times hit .25 moa groups with .5-.6 moa on the worst groups. That was more a factor of me than the individual loads or bullets. Sometimes I held good and sometimes I didn't. But bottom line the rifle shot as good as I could with all bullets listed.

The best load I found that continuously shot extreme groups was the 210 grain Berger bullet with 99 grains of WC-860 using fed 215 match primers with a 3.7595" coal which is .01" off the lands. This rifle liked the Bergers seated off the lands. The best loads were seated .006-.01 off the lands. This load shot one of the better groups of 1.369" at 500 yards. This is the only load I have carried beyond 600 yards and only for one group. I set the target on the mountain behind the range then went back to the bench and ranged it at 911 yards. The one group measured 4.966". This is the load I will be shooting for the long range test to 1000 yards. At 3071 fps average the load is slower than the Retumbo loads however extreme spreads are single digit and I go with the accuracy and not the velocity. The Retumbo loads averaged about 80 fps faster.

The 180 grain c32 cutting edge bullet touched the lands at a coal of 3.893". It shot best in this rifle at 3.784" coal. The best load was 97 grains Retumbo, fed 215 match with a velocity of 3402-3407 fps. I could easily push this bullet to over 3450 fps with no pressure but this load was the most accurate at a slower velocity.

The 200 grain Accubond touched the lands at 3.764" coal. 3.759" proved to be very accurate with 93 grains of Retumbo and the fed 215 match primer. The velocity with this load averaged 3233 fps.

The 208 A-max touched the lands at a coal of 3.831". I loaded this bullet to a coal of 3.769" so it would eject through the G30 action since it is a hunting rifle and I felt most would want to know how it shot loaded as a repeater. At .062" off the lands this bullet shot .25-.5 moa repeatedly. Again WC-860 was the most accurate powder with loads between 98-99 grains giving very consistent velocity spreads and accuracy. Velocities averaged 3040-3080 fps with this powder. 91.5 grains of retumbo also shot excellent groups at 3160 fps.

I hope to post some group pictures tomorrow at the 200-600 yard targets with these different loads. Then I will post the long range targets as i shoot them using only the 210 Berger load since this rifle is built around using this bullet long range.

Re: Range Test Mcmillan EOL Outdoorsman

That's comming right along LTLR.
Glad your testing many different kinds of bullets, even if only out to 600yds.
The performance of all those bullets speaks volumes about a few things, Namely, a quality built firearm, but it also confirms that you were an exelent choice for an honest tester. Handloading skills, & shooting skills are a must. You obviously possess those, & I'm sure no one ever doubted that, but taking the time to work up that many loads, just for our sake, when the rifle was built for an entirely different bullet.... Thank you for all your effort put into the testing, for ALL of us.
Can't wait to see pics, & read how she does when you streach its legs!
(your having fun aren't you )
Keep us posted.

Re: Range Test Mcmillan EOL Outdoorsman

Here are a few targets I shot last week. This is a continuing thread so I will update it as I shoot more targets. I tried to show different bullets and loads. If anyone has something they would like me to try in it let me know and I will try it. On my way to the SHOT Show now and will not be back until next weekend.

Many people I talk to shoot the 200 grain nosler Accubond bullet for long range out of the 300 RUM so I wanted to show the best load in this rifle and what it would do at various distances. I thought it shot this bullet very well. Also the bottom target shows a good group with the 208 grain Hornady Amax bullet.

The top target shows me blowing two exceptional groups with the first two shots through the same hole in both groups and then jerking the next, typical. A velocity drop cost me one target which was reloading. Probably a brass issue from not enough brass prep.

The bottom target shows several loads stretching out to the 600 yard target. I think the fact that this rifle basically shoots anything well is a testament to how well built it is. this shows one of the good groups with the 210 Berger and WC-860. That combination continued to shoot exceptional throughout the test so far. I am looking forward to getting that one out to 1000 yards.
