Hi, all. I'm thinking of trying some 225 MRX in my 338 WM. I'm curious if anyone has compared them directly with the 225 AB. Are they longer? Were you able to get them to the same velocity? Accuracy?
Any replies would be appreciated. Thanks.
I now have two .338 AB's I can shoot. I am in the final stages of dialing in my 250gr AB, & have a 225gr. all ready.
So, which would be your "Go To" bullet.
They shoot the same groups,(1/2" MOA or better)
The 225 shoots a few inches flatter, with a hundred fps. more velocity, but the 250...
I'm wondering what other signs to look for when gauging pressures in a belted magnum. I know about sticky bolts, & cratered primers. Is there something else to look for?
Hey all. I just bought my 1st box of 250gr. AB's for my .338WM I was supprised at how long they are. I was going to just throw a few on my pet load for my 250 SGK's but they are sooo much longer I don't think that will work.
So here's what I want to use.
H-4350, or H-4831
COAL of 3.390"...
I'm wondering what potential problems,if any,there are with seating a long bullet into the case,& ending up with 1/4" of bullet protruding into the case neck.Such as whith my 300 WM & seating a 220gr. Sierra Match to SAMMI COAL.It shoots them well that way,as long as they're straight.
I'm debating whether or not to put my load back where it was. I'm loading for my custom 300 WM for precision long range shooting,& I used to seat a 220gr. Sierra Matchking to SAMMI spec,oal.But after doing some research I learned that I should seat closer to the lands.But,here's the thing. I was...
I'm looking for a good sandbag to hold in my off hand under the butstock on my F-Class rifle.I'm thinking it should be a small cylinder about the size of a baseball. I would squeeze it to adjust elevation.Any Ideas? I thought of a Hacky Sack ,but all the ones I've found so far are too small.Thanks.
Well,today I was able to get to the range,& fire 2 strings @ 500yds. in F-Class competition.Just a practice,but my first with the new smaller targets. :shock: I shot a 193,& 3X's on the first string.& a 192,& 2 X's on the second.Since there aren't many F-Class shooters around here.What's a GOOD...
I finally recieved my case,& cartridge checker from Forester.I checked a batch of 50 I had loaded a few weeks ago,& found allmost all of them to be @ .0001"-.003".But I had 4 that were@ .004",& one that was @ .005".The instructions said anything above .004" was suspect.My question is.What is a...
I have been loading my 300 WM with 220gr.Sierra MatchKings for a couple years now,& Hadn't thought too much about how much bullet was inside the case 'till now.I have changed my seating depth .210" longer.I was seating them to the SAMMI Max OAL of 3.340".Now they are @ 3.550".This is within the...
High.I was trying to get a load to work on the Quick Load demo,& don't know where to get the specs for the powder.Anybody know what the Energy Density/Bulk Density/etc. is for H4831?Thanks.
High all,I just wanted to say that I had a great time @ Machias today.I was the only F-Class shooter there,but Nobody seemed to mind.Everyone was friendly,& helpfull.It was snowing most of the time,but not enough to affect the scores.I shot 3 strings of 20.The first,& second in sucsession,&...
I'm curious about the published B.C. for the 225gr. 338 AB.It's listed as .549 B.C.Thats only.010 +/- the 250gr. SGK.While the 225gr. Partition is listed @ .454 B.C.I'm asking because I have tested it @ ranges up to 500yds.,& my results suggest that it performes closer to the Partition.Also,my...
I switched from Sierra GK's to Nosler AB's,& after running all the info I had through my Infinity program,I got a supprise.The calculated trajectory for my MV was off a lot at long range.The AB's POI was consistantly lower than the computer said.Like 5"-7" @ 500yds.I've tripple checked my...
I was useing the 338 cal.250gr. Sierra Game King for several years,before realizing that I suffered from magazine deformation.(Bad)I then switched to the 225gr.AB.Since I have a Winchester BOSS.Accuracy isn't an issue.(It will shoot anything if adjusted right.)But I can't get my AB's over...
