I have been doing battle with my 338 WM and the 225 AB for years trying to get it to shoot under the 1" mark on a regular basis. I found a load with RL-17 that would get me right around 1", and has done so several times. I got a new can of RL-17, and some more 225 ABs this week so I decided to run some tests.
I loaded 14 rounds up with 68.5 RL-17 and a 225 AB @ 3.360 and Fed 215M primers
Loaded 3 of the same thing with WRLM primers.
And three more of the same thing with CCI mag primers.
The 215 load typically clips along at 2830 fps. Nothing that is going to set any land speed records, but capable of running down any critter I point it at. I'll take it, even @ 1". But
I had to try to do better, and I had a few different primers laying around.
I also cleaned the everliving crap out fo the barrel before I went out. I'm talking a few applications of JB compound, and some CR-10, and a bunch of elbow grease!
After two foulers with the 215, I got a nice 1" 3 shot group.
I switched to the CCIs, and things got worse!
Next up was the WLRM, things got better, about .5" better! I got a nice three shot group that will be right close to .5"
I used the rest of the 215 rounds to play with the Limbsaver barrel Deressinator (sp?) I started @ 1/2" from the forend of the stock and shot a three shot gourp, moved it out to .75" and shot a three shot group, then moved it out to 1" and shot another three shot group. I won't put these pics up, but the groups gots worse the closer the "rubber" was to the stock. None of the groups in this case were better than the groups shot without it. The only group of the day that was shot without it that was worse was the CCI group.
All in all I'm freaking stroked about the group I got with the WLRM. I'll load a few more and try to repeat it to make sure. This has happened to me before, I got all excited about a load, then could never get it to happen again. This time MIGHT be different.
I'll get some pics up here soon, the bear meatloaf experiment is about done!
