    Lost 100 fps after 550 rounds

    Update: I measured the distance to lands, and I only lost 7 thou. Safe to say it's not that erosion? I'm waiting for the Xero C1 to go on sale in December to buy one. That should be a good indication if one of the labradar was off. The other suspect might be the abrasive paste, I'll take the...

    Lost 100 fps after 550 rounds

    To answer a few questions: I don't care about barrel life. 500 rds vs 3000 rds is the same for me—just a few more barrels. The purpose of this thread is to find the culprit so I can take appropriate measures. Increase powder or order a new barrel. With mono bullets, it is pretty...

    Lost 100 fps after 550 rounds

    I'll do that, thanks for the idea. I never had issues with temp stable powders and different lots. I don't mind burning a barrel, I just didn't know what was wrong with it.

    I'll get back with more details once I play with powder weight.

    Lost 100 fps after 550 rounds

    Yes. I live in Canada; the rifle was shot from -13 to 95F and anything in between. I keep the ammo in my chest pocket to avoid big temperature swings. I recorded the MV in different temperatures from -10 to about 90F; the MV variance was so small that I didn't include it in my ballistic...

    Lost 100 fps after 550 rounds

    Hello, I have a carbon barrel that lost about 100 fps after less than 600 rounds. I looked at my order history, I have 400 bullets ordered, 100 that a buddy bought for me and 80 factory loads. I would appreciate some thoughts on the matter. I went to the gun range two weeks ago and noticed that...

    Pre-fit barrels

    What do you do with the scope? Switch zeros to follow the barrels?

    Pre-fit barrels

    Hello, I want to move to pre-fit barrels between my two rifles: 300 PRC, Defiance action, carbon wrap barrel chambered by a smith Tikka T3x 300WM all factory. I have a few questions that I can't seem to wrap my head around: For my Tikka rifle, if I want to buy two pre-fit barrels, one in 7...

    7 SAUM

    Good point. You made everyone curious about your barrel now haha What barrel is that? How many grooves?

    7 SAUM

    Very much. Did you try other powders? RL26 is not temp stable for my needs.

    7 SAUM

    My next build will be a 7 SAUM around the 143g Hammer Hunter bullet. If you are shooting a 7 SAUM with a 21-22in barrel please share your velocity, powder and bullet weight.

    Free All and CLR

    I see a few people on youtube using CLR and Free All to clean their barrels. I have 2 rifles with heavy carbon deposits. I tried a few things but it takes so much time. Any thoughts on Free All and CLR?

    Starting from scratch - First Lite or Kuiu?

    I am a fan of trial and error, therefore I own both Sitka and KUIU. I have nothing against first lite they are not really available to me. I prefer KUIU because they have a rep here, I can actually see the clothes feel them and try them on. I don’t think you can go wrong with any of the big...
