    Advanced Marksmanship High/Low Angle Shooting - When Do I need to worry about making an Angle Correction?

    I am now questioning the accuracy of some ballistic solvers when it comes to high angle predictions. I found a new spot where I was shooting at 1100-1400yds @ -12* & 4DOF gave a .3 mil difference from FFS. Both have been spot on at smaller angles. I chose FFS & it was correct. 4DOF was .3 mil...

    IMR 8133 for 300WM?

    Yep. I found those also before I posted here. Was hoping someone has run it with some 230gr Berger's, or A-Tips. I can't find any to try myself but the Hodgdon data looks very promising. Thanks.

    IMR 8133 for 300WM?

    Not 1 reply? Nobody has any comment on this question. No one has tried 8133 in a 300WM?

    IMR 8133 for 300WM?

    Hi everyone. I've been shooting my 300 WM almost exclusively for a long time for ELR work. Been using the 225 ELDM lately in this barrel. (its 3rd) with H-1000. Been using H-1000 since my 1st barrel. Now I'm wondering if there's something better since some new powders have come out. Has anyone...

    LH Gain twist.

    I'm liking it. Hopefully I'll be able to get the same results as my last barrel. 2900 fps & bug hole groups. Now if the 4DOF app would let me click something for a LH twist...

    LH Gain twist.

    Thanks. I went with a 9.5-8.75 twist. Not going to get the 250s going fast enough to outperform the 220-230gr bullets anyway so I went just a touch faster than the minimum twist for the 230 a tips.

    LH Gain twist.

    My current barrel really likes the 225 ELDM @ 2800 fps but is 100 fps slower than my last barrel running the 230 Bergers. That one was a 10" twist. This one is a 9.5" twist. Can I assume that if I end up pushing the 225's at 2900 in a 8 or 8.5" twist I will e Ok? Need to figure this out asap. I...

    LH Gain twist.

    Yes. That was basically what I was asking. Everything I've read says that a fast twist at ultra high velocity can cause blowups. But could I get to that point with 200+ grain bullets in a 300WM or even a prc? What is the point of diminishing returns when it comes to twist? Will a 220gr going...

    LH Gain twist.

    I was debating whether or not to make the switch to the 300prc. Hesitant because of all the new 300WM brass I have in unopened bags. Also wondering if you can really over stabilize a bullet if not also pushing it to obscene velocity.

    LH Gain twist.

    Hi all. I'm in the planning process for my next barrel for my 300wm. I've decided that I want to try a LH gain twist. The question is what twist? I'm probably going to run the 220 berger, 225 ELDM, or 230 berger or a tip. Depending on what mv I can get out of the new barrel I may also try the...

    Razor HD Gen II 4.5-27 vs ATACR 5-25 F1

    Looking to finally upgrade my old NXS 5.5-22X56 to one of these but can't actually look them over in person. Anyone have real world knowledge for comparison? Mostly interested in Actual elevation travel (have a 40 moa base) and optical clarity. The...

    198g flatline

    I was afraid of that. Oh well, was a fun idea.

    198g flatline

    Great! I'll be interested in your findings.

    198g flatline

    Its a "match" chamber. I don't know the specs. I do know that the 225 ELDM are .015" off the lands @ 2.825" to the ogive. Doing the math with the measurements Mr. Warner provided & his posted COAL in the load data the 198's would be 2.6". That would be nearly a 1/4" jump.

    198g flatline

    Ok so doing the math if I were going to seat them to the published OAL in my barrel they would be jumping .235" to the lands. Question now becomes if I seat them longer will there be enough bearing surface in the neck to hold the bullet?

    198g flatline

    . 510" from the base of the bullet. I can do the math from there. Thank you.

    198g flatline

    Looking at Warners load data I see they list a OAL for the cartridge. 300WM for me. Can anyone tell me what the base to ogive length is for the 180 & 198gr at the published OAL? Thanks.

    Backpacking food

    Looking to pack into the wilderness for the high buck this year. 1st time since just after 911. Looking at light weight food for the hunt. I like some of the Mountain House bkfst & dinners but they are only 200-300 calories per serving. I'm likely to...

    How many of us have lived through this virus already?

    Virtually positive my boss & I got it at the Seattle boat show last week of Jan. Was pretty sick for a week then just not well for at least 2 more after that.

    .300wm - .300wsm

    I have 1500 ELDM 225s down the pipe in my Benchmark 9.5 tw 28" tube. .015" jump with 74.1-74.5gr H1k depending on lot. 2800fps. They put 1hole groups @ 100 & under favorable conditions I've gone 7/10 rnds at a mile with them.
