Recoil Calculator

I dont know if this is reliable, but it seems like it should be? I just used it to compare some cartridges, and I think the pain I felt in comparison to what their figures are fall right in line with each other. Its a real eye opener when you use it. My 454 Casull has more recoil energy than my 338 (with the loads I compared, not all loads), and no wonder my .458 hurts me, it dwarfs my 338's recoil energy, with light loads. I'm sure glad I have the 338 ported, or I'd feel more than what I do. Try this calculator out and tell me if you think its correct in relation to your guns, and how they feel on your shoulder.
Duh, how about the link huh? http://www.beartoothbullets.com/rescources/calculators/php/recoil.htm?

    Thats pretty cool, but what if you have a muzzel break ... or your a wuss like me and put Recoil Eleminators on? Hummm? My M1A and Rem 700 (both in 308) kick about like an AR without a break ... and my AR with a Recoil Eleminator "kicks" about as much as a 10-22 ... haven't put one on a 10-22 yet though

    What I'd really like to find is a calculator that would convert powder charges ... let me explain;

    You've been using the same powder for years, and for whatever reason, decide to change or try something different. You have a load for weapon (rifle in my case) that shoots sub-MOA groups ... you enter your calibur, bullet weight, type and weight of powder for the known load and maybe the barrel length. Then enter the new powder you want to switch to, click the calculate button then WA-LA! It tells you how much of the new powder to use to achive the same sub-MOA results! I dont think you should have to enter velocity (fps) or barrel twist yada, yada, yada ... because all you are changing is the powder, everything else is the same, the calculator should "know" the burn rate of the powder and the energy produced to come up with powder weight for the new load.

    I only mention this because I'm in the process of working up new loads for about 15 different rifles ... Its time consuming and fairly expensive work them up, plus you load rounds that don't preform ... then add that to having to find time and drive out to the range (some 35 miles from my home). Fortunately, some rifles will shoot the same load, for instance my SL8 and AR varmint gun both shoot the same load sub-MOA, even though the SL8 has a 20" barrel and the AR has a 24" ... go figure ...

    KK: Getting a program to calculate the barrel harmonics with different powder types could be a problem. It's not just the velocity that matters, but how the pressure curve affects the barrel vibration.
    As far as recoil goes, the programs calculate "Free Recoil" which is a math function (M/V=M/V), but can't do a compairison of the "Felt Recoil" which is affected by time, stock shape, etc.
    Some guys like a mag full of lead, I still prefer one round to the head.

    robsguns....This is a GREAT thing you posted!! I've been wondering about this very subject. I need to eliminate a lot of recoil in my deer rifles by fall, or buy me another shooter. Three heart operations in the last year and a sternum that won't heal has severly effected how much I shoot. I'm only shooting my 22-250 now and it still hurts. I need to make something I can shoot and concentrate on one-shot kills. A .243 with a muzzle brake or Recoil Eliminator? BTW, what is a Recoil Eliminator?? Is this like a Decelerator pad? Anyway, I already have my deer tags and I don't want them to go to waste. Suggestions??
    Thanks,
    muley

    muley - I was referring to the JP Enterprise Recoil Eleminator; its a dual chambered muzzel brake, the exit hole is just large enough for the bullet to pass through while diverting the remaining gasses to the sides. They work on the same principal as the brake 50 BMG's use, JP's have been around for at least 6-7 years, maybe more. I think they are the most effective brake on the market. You can check them out at www.jpar15.com ... they have lots of cool stuff!



    Tailgunner1954 - I should have known it couldn't be that simple!

    Kimberkid.....that thing is as ugly as my first girlfriend. However, I got used to her too. Thanks a lot for the information. I'll check it out.

    Yeah, but are Glocks are ugly too ... still, I have a couple of them They do look somewhat better in stainless and on a bull barrel ... if they wern't so effective I wouldn't have 3 rifles with them ...
