We’ve had quite a discussion on this subject, and we also decided, by a unanimous decision, to add the following advice to help you to interpret the following table.Īny rifle that has a Recoil Factor of less than 100 can be shot by anyone that can handle a rifle.īetween 200 and 300 is moderately heavy. It is really nothing more than multiplying the recoil velocity by the recoil force. He thought it would make it easier to understand. The data in the last column was included at the urging of one of our geniuses here. We used weights of rifles that we have on record, and we used powder charges and bullets pulled from factory ammo for our data entry.įor some of the popular calibers we have included data on more than one bullet weight. We tried to be as accurate as we possibly can. Also, I have found that on some days I feel the recoil of the rifles that I shoot more than others.Īll the following were worked through LOAD FROM A DISK program, other programs might give you different results. These include the weight and shape of the stock and how they fit you. Please bear in mind that there are several factors affecting the "felt recoil" of any rifle that you shoot. Review.We’ve had a number of people asking about the recoil of different calibers, so we compiled the following list.

The absolute EC50/IC50 should only be used if there are at least two assay concentrations whose predicted response is less than 50% and two whose predicted response is greater than 50%.
The relative EC50/IC50 should only be used if there are at least two assay concentrations beyond the lower and upper bend points. Next, the guidelines provide rules for deciding when the EC50/IC50 estimates are reportable. Assays that can be demonstrated to produce an accurate and stable 100% control and less than 5% error in the estimate of the 50% control mean may gain efficiency as well as accuracy by using the absolute EC50/IC50. Assays having a stable 100% control but for which there may be more than 5% error in the estimate of the 50% control mean should use the relative EC50/IC50. Assays for which there is no stable 100% control must use the relative EC50/IC50.

The guidelines first describe how to decide whether to use the relative EC50/IC50 or the absolute EC50/IC50. The absolute EC50/IC50 is the response corresponding to the 50% control (the mean of the 0% and 100% assay controls). The relative EC50/IC50 is the parameter c in the 4-parameter logistic model and is the concentration corresponding to a response midway between the estimates of the lower and upper plateaus. Two definitions of EC50/IC50s are considered: relative and absolute. This article provides minimum requirements for having confidence in the accuracy of EC50/IC50 estimates.
