    Help me look for pressure signs (7mm-08)

    Hi, One can get extrusion and swipe marks in the brass and not be necessarily related to dangerous pressures. Even factory ammo might show this and could be more a condition of the gun and/or bolt than anything else. For example if the ejector plunger hole has not been properly chamfered or the...

    Help me look for pressure signs (7mm-08)

    It looks good. I believe could even push a bit more for hunting loads but brass will not last as long. So around that pickup what groups best and test again when it gets warmer to see if you need to backout specially with big game. ...just the normal consideration to get the spreads with...

    Why isn't the 7mm-08 more popular?

    You probably know this but during the Army trials prior to WWII the army discovered they didn't like the Pedersen rifle and loved the M1 Garand but they pretty much preferred the 7mm Rederson round. So the original Garand was going to be a 7mm (.276 Pedersen) rifle until they received a...

    160gr accubond are great bullets. 120gr TTSX can be pushed at 270 winchester speeds (3100fps) so those are brutal for white tail and hogs too and very flat shooting. It really depends on what you want to do.

    Why isn't the 7mm-08 more popular?

    The thing is the "kicking like a mule" is all relative and subjective to perception because it depends on so many factors like the weight of the rifle, weight distribution, ergonomics, etc.. So a crude and light 300 savage wiht heavy loads can in fact feel uncomfortable while a heavier win mag...

    Why isn't the 7mm-08 more popular?

    The inexpensive axis is actually a great platform to build a pretty decent budget rifle. The magazines give up to 3.2" that is the longest of all the magazines so for special projects are awesome and the actions are very strong regardless of their "budget" gun status. The nice thing is that...

    Why isn't the 7mm-08 more popular?

    I don't think it would and published data is just a reference and not 100% accurate. For now I have retired the 260 in an effort to consolidate and reduce caliber footprint that was getting crazy. Amazing round tough.

    Help me look for pressure signs (7mm-08)

    Pressure signs many times come in twos and threes. One should always look for all of them and not one in particular. IMO jumping into a magnum is not necessary in this case. The 7mm/08 is a very efficient case just like the 308 itself, but with better ballistics. Books and manuals are not...

    Help me look for pressure signs (7mm-08)

    Remember that everything is relative. Your chrono might be off up or down that is normal to have a % error with inexpensive machines. that is why companies are going to better systems including Doppler vs. the light sensor or magnetic no matter how long they are. 2900 is possible but possibly...

    Help me look for pressure signs (7mm-08)

    Looking at the primers is always a good thing but not the only thing and of limited value. Normally signs of problems come in twos. Even a flat primer alone might be a sign that certain level has been reached but not necessarily that the pressure is close to the maximum for that case or...

    RL-19 in 7mm-08. VERY slow velocities?

    I agree. The ranking is different for different makers that is quite confusing so the best thing would be to converge information and the asses corroborating with the other resources. This is a source for huge confusion and why going to the different sources is always a good idea. That is why I...

    RL-19 in 7mm-08. VERY slow velocities?

    No specific source but over the years it has been posted in several forums by ex-employees of powder companies along with other answers to various questions about powders. Also it explains why the inconsistencies between popular loads and other loads including the bullet manufacturer data for...

    RL-19 in 7mm-08. VERY slow velocities?

    At the risk of sounding redundant let me repeat this: - Books and manuals are a reference and load data is not accurate. Many are not even tested just estimated plus it looks they are written by lawyers vs. ballistics experts. They take the safe, less liability route. Accurate arms data seems a...

    RL-19 in 7mm-08. VERY slow velocities?

    The R19 is on the slow side. Will work best with the heaviest bullets and longest barrels. The thing with reloading manuals is that they are not accurate. Things like type of rifling, temperature, freebore, length of barrel and finishing of the bore, all variables play a role. Many are...

    Why isn't the 7mm-08 more popular?

    Well that is an issue for the longer bullets but one can work around. Can the magazine be gated? One would hope all brands will give around the same coal than the AI/AW mags that has stablished itself like the standard. But yeah! ... one good reason to put a nice bottom metal also if you decide...

    I am not a huge fun of you-tube because of the amount of garbage that is in there, specially firearm "reviews". But once in a while one finds good stuff and folks who are entertaining and take the time to explain things reasonably well. A lot of people explain how to do things and push fashions...

    That is very nice. I woudl find the max coal for each bullet on that new rifle based on the freebore or magazine, whichever comes first. BTW what is the max coal you can get in the tikka magazine? ..more or less... ...just curiosity.

    Why isn't the 7mm-08 more popular?

    I was texting with another member and remembered we had some load data in the reload section so do a search there for 7mm-08 loads. Reloader 17 is a great powder for the 150-165gr bullets, that is no secret. R19, hunter and other slighter slower I would leave them for the longest barrels and...
