Its here 1-20
 

Went to the range today with the mountaineer 45cal 1-20 I was just shooting just to see what's up with the gun and adjusting the scope. used BH209 W209 primers and Hornady .40 200gr XTP and harvester blue smooth side sabot for all shots. all shots were at 100yds. shots 1-4 was 105gr to adjust scope then 110gr was 5-8 and then bottom right was 120gr 1-3. there was no cool down time between shoots for heating up the dyno coating in the bore. I would say it was a fun time doing a little shooting and the first time out with this gun. and it was 85 deg out the barrel got good and hot." />
plus I ran off and left my front rest and had to try to us what I had to make one and it was not good one.

I would suggest heating that barrel up a few times before shooting in for hunting. I would suggest doing it sabot less if you can. Can't wait to see your results in the future.

If I had one I would replace the stock with a Kevlar stock. Cut 2 inches off the barrel and have it crowned. I would then have the breech plug drilled out 5/32 and tapped for a vent liner. Wow, that seems like a lot of work, but so easy to do at the factory😉

I would have loved to had the Kevlar stock but only on the ulite and they will not sale one. next outing will be using 270gr E max with wad and will see what that looks like on a good hot bore.

I dont think you would like it too light when shooting heavy sabotless loads. My Super DISC will rock you pretty good with 120gr of BH209 and a 300gr bullet.

It will be interesting to see how well the Mountaineer handles heavy sabotless loads. Im mainly curious about how well the primers extract after shooting them.

Handles 120 gr by volume with 270 emax fine but from 110 gr on mine requires a quick dry fire in order to extract the primer
I will probably stay around 120 . If i shoot hotter loads i think i will do it from my custom Omega

I have two breech plug one setup for W209 and one CCI209M will see if there's any change in primers sticking in the breech plug. in my last outing with W209 I had some stick with 105gr & 110gr but not 120gr also. in may 1-30 twist mountaineer I had none stick with it setup for CCI209M from 100gr to 120gr. just working the bugs out.

I would modify that plug for sure.

Arent the new Knight bare primer plugs already 5/32" Im sure that is the size my Lehigh plug takes to clean.

It sounds like you need to but some washer in the breech plug for your head spacing mine just sticks in the breech plug not the bolt I may have to change the thickness of my washer may be to much making the primer blog on the end of the primer when closed. 5/32 is what I us to clean mine.

On Knights website they now have a new Extreme bare primer system. They made the new one similar to the Mountaineer bare primer system. Ive been very pleased with the old style Lehigh plugs and bolt adapter. The only one that will stick regularly is in the Super DISC with Fed209As. It happens pretty much every shot.
